Safari freezes on some sites

It was launched recently, perhaps just after I upgraded to Mac OS sierra.

When I open some site like github.com, pypi.python.org, other, Safari hangs for a 5 seconds or more and shows the spinning ball. If I open another tab and return to the tab of the github, it will freeze again.

I tried to clear the caches, cookies, delete the "plist. Safari - nothing works Other browsers like Firefox work very well with the sites.

Is it possible to fix it? I use sites all the time and it is very annoying to wait more than 5 seconds, whenever I open them

  • Safari freezes on YouTube HD videos

    Hello

    I have a MBP early 2015 with no upgrade. Whenever I try to watch a 720 p or of superior quality videos on YouTube, Safari keeps after some time of freezing with the icon of the Rainbow or forwarding, change the size of the screen etc. The mouse does not freeze btw. I have not tried other Web sites, and Chrome works very well. I tried clearing cache, history and remove the extensions and finally Reset Safari. Nothing has worked.

    Everyone knows these? Is there a solution?

    Thanks in advance for your answers.

  • Some sites do not open

    Hello

    I had a very bad day, and I end up spend almost the whole day this question of fixing. There are some sites Web do not open in my macbook air, when I boot in safe mode, it works but it does not work in normal mode. It happens across browsers IE, chrome and safari. Open all the apple websites, Facebook, google pages, but there are many other websites do not load. I feel that it goes to the Web site with the service of google ads, but I'm not sure. I tried almost everything as clear cache dns, restart system, router, try another network, looking for suspected of process and to kill them but nothing works. Can someone help me please in the question of fixing. As a last resort I will reinstall the OS, before to do that I would like to confirm that it will not affect the files in my system?

    You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

    Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

    Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

    Step 1

    VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

    Step 2

    When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:

    /Library/LaunchDaemons

    In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

    A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

    There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

    Step 3

    In the LaunchDaemons folder, there may be one or more files with the name of this form:

    com Apple.something.plist

    When something is a random string, without the letters, different in each case.

    Note that the name consists of four words separated by dots. Typical examples are:

    com Apple.builins.plist

    com Apple.cereng.plist

    com Apple.nysgar.plist

    There may be one or more items with a name of the form:

    com.something.plist

    Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

    These names consist of three words separated by dots. Typical examples are:

    com.semifasciaUpd.plist

    com.ubuiling.plist

    Sometimes there are items (usually not more than one) with the name of this form:

    com.something .net - preferences.plist

    This name consists of four words (the third hyphen) separated by periods. Typical example:

    com.jangly .net - preferences.plist

    Drag all items in the basket. You may be prompted for administrator login password.

    Restart the computer and empty the trash.

    Examples of legitimate files located in the same folder:

    com.apple.FinalCutServer.fcsvr_ldsd.plist

    com Apple.Installer.osmessagetracing.plist

    com Apple.Qmaster.qmasterd.plist

    com Apple.aelwriter.plist

    com Apple.SERVERD.plist

    com Tether.plist

    The first three are clearly not VSearch files because the names do not match the above models. The last three are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these files will be present in most installations of Mac OS X.

    Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

    If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

    If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

    Step 4

    Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

    ▹ Safari preferences... ▹ General

    and click on

    Set on the current Page

    If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

    The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

    Step 5

    The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a reason, skip this step. Otherwise, you should undo the change.

    Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, and then apply.

    Step 6

    This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be some with random names that have been added by the malware. You can remove these users. If you are not sure whether a user is legitimate, do not delete it.

  • Drop-down menus on some sites no longer trigger a chosen time

    Starting from the version 24 (on a Mac Pro running OS 10.9), on some sites, such as http://download.cnet.com/new-mac-software/?tag=rb_wrap;rb_content;main, menu items will stop working. Options for, in this case, display more results will be visible, but only the default action can be selected. Similarly, trying to connect (to post comments on pages such as http://www.newrepublic.com/article/115817/stephen-fry-responds-grammar-pedants) or present the login window, accept the entry and fail to complete the connection, or, Alternatively, do not show the login window at all.

    In each of these instances, I turn to Safari (where these actions run perfectly), and the need to do what is clearly indicating that Firefox cannot qualify as my default browser.

    You can try the following steps in case of problems with web pages:

    Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    Clear the cache and cookies only from Web sites that are causing problems.

    "Clear the Cache":

    • Firefox > Preferences > advanced > network > content caching Web: 'clear now '.

    'Delete Cookies' sites causing problems:

    • Firefox > Preferences > privacy > Cookies: "show the Cookies".

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the startup window Mode without failure.

  • Some sites (random) Web would not load

    Hello

    I had a weird problem with my MacBook Pro: some Web sites load perfectly fast, others not at all or would take 1-2 minutes to solve. The split between those that charge and those who are not seems random. Examples:

    Load

    Facebook.com, google.com, spiegel.de bbc.com

    Do not load

    Sueddeutsche.de, faz.net, strongvpn.com

    --> My guts together feeling says that 40% of known Web sites work perfectly well, 60 percent are related to the problem. The accident is compatible, for example, or a Web site falls under the first or second category.

    TEC Spec:

    • MacBook Pro 2.6 Ghz Intel Core i &
    • 16 GB 1600 Mhz DDR3 memory
    • 10.9.5 OSX version

    Other aspects of the problem:

    • I don't travel a lot, but I only experience this issue in this House a special router in Germany.
    • It occurs identically in Safari, Firefox and Chrome. Needless to mention: I did the clear-the-cache-and-cookies-thing integer.
    • It happens only with my Mac. If I use my iPhone or iPad in the same spot WiFi, no problem.
    • The problem occurs both through WiFi and if I connect via a cable (ethernet)
    • With sites that create problems, there is the white page on the browser with information (for example in Chrome) below on the left, for example "waiting for fast.fonts.net", "waiting for imasdk.googleapis.com", "waiting for gwp.nuggad.net". Looks like typical calls on content at the beginning of the process of loading sites. Without doubt, it will not be a DNS problem. I have indeed changed the configuration of the DNS for example to Google "8.8.8.8" and "8.8.4.4" - in vain.

    Any reference to the resolution would be very appreciated.

    Some sites are slower than others. It is a fact. The display of the Web site may be delayed because of connections to the ad sites, content sites, etc..

    Modern Web sites have different format and content to the iPad, iPhone and desktop browsers. The fact that their access via iPhone or iPad does not indicate that your Mac has a problem. That fact could help Web site developers to improve the performance of their site on desktop browsers.

  • Could not load some site

    Hello

    I'm new to Mac and used the iMac for 4 months.

    Starting yesterday I noticed that some site are no load, while others are very well.

    I tried it with Safari and Chrome, and the result is the same.

    However if I restart in safe mode these Web site would work.

    If I reboot and return to normal mode, these site not load again.

    For Internet connection, I tried the cable and wifi and no difference.

    On the same network, I have another iPad and has no problem to access the same Web site.

    Tried with App Store, some graphs also have problems to load and some display a question mark.

    Welcome any comments or advice on the probable cause of the issue and how it can be solved.

    Me too same, same case! iMac, OS X El Capitan (10.11.3)

    Same problem after upgrade-> Safari, Chrome, Firefox, and App Store

    I realease 1--> only HTTPS works very well but accident of HTTP

    BTW, all internet applications work fine, I mean, if I use FTP (filezilla) work very well, if I use another app with internet connection WORKS FINE

    Only browsers in HTTP

  • Very confused! Mac OS El Capitan and Cisco WLC5508/Aironet3702i some sites won't load is not on wifi

    All,

    A strange behavior.

    Worked for the last great 9 months, but here is the story.

    Environment:

    ASA5516-X, ASA5505, ASA5510

    * A tried all three, thinking that it was a firewall issue.

    WLC5508 and AP3702i 17

    Catalyst2960 switches

    Recently, my Mac cannot access some sites like aol.com, cisco.com, apple.com and paychex.com of a wired connection (adapter Thunderbolt) my catalyst switch. Wifi, cannot access some sites like google and yahoo and not those listed above. Portable windows can access all the websites all the time over wireless connections or wired my computers?

    We have 5 macs in the building and they all have the same problem. Him are wired for now, but I'd like to be able to solve this problem.

    Also I used to be able to telnet to my switch and firewall on wifi it will connect, but no data appears to indicate that I am in the prompt of cisco device.

    Any ideas on what could happen?

    I even restored my original config back to the first date that everything was fine.

    Thank you

    Hello

    I have a problem quite identical to this step-by-step helped: (for some users it did not work)

    http://techrumours.weebly.com/tech-solutions/some-website-not-loading-up...

    When you're connected via wifi, rather than access Web sites via safari or chrome, have you tried their ping via terminal to check the dns configuration.

    If the ping of through terminal host name does not work then resolve ip on a windows and try to ping ip to ensure that Internet accessibility.

    Mac and windows are connecting even though she ssid and get the same authorization?

  • Some site to load then receive errors like this: (function() {var _UDS_CONST_LOCALE = "en";) Uninstalled and reinstalled firefox. No help.

    Some sites work very well. I have Firefox on my work PC and laptop. I can open incandescence.com on them, but on this desk, it loads a page with what follows, 1000's of lines like the following:
    (function() {}
    var _UDS_CONST_LOCALE = "en";
    var _UDS_CONST_SHORT_DATE_PATTERN = 'MDY ';
    var _UDS_MSG_SEARCHER_IMAGE = ("Image");

    var _UDS_MSG_SEARCHER_BLOG = ('Blog');
    var _UDS_MSG_SEARCHER_VIDEO = ('Video');
    var _UDS_MSG_SEARCHER_LOCAL = ('Local');

    There are pages of the below. Some sites go up and try to open Notepad. I uninstalled firefox several times and reinstalled. Same results. I noticed that my bookmarks, etc. themselves so maybe uninstall/reinstall cleaning isn't the problem. Chrome, IE, Edge and all work very well on the sites in question.

    He takes me to the following address instead of incandescence.com: http://www.google.com/uds/api/search/1.0/432dd570d1a386253361f581254f9ca1/default+en.I.js? & a = 1

    Thank you...

    Maybe a content filtering went wrong. Could test you mode without failure of Firefox? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

    Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

    If Firefox is running: You can restart Firefox in Mode safe mode using either:

    • button "3-bar" menu > "?" button > restart with disabled modules
    • Help menu > restart with disabled modules

    and OK reboot.

    Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

    Any improvement?

  • Page Firefox blocks, led busy, very low cpu on some sites. I have an example.

    Firefox 41.0, win 10 Pro x 64.
    Recently (possibly before v.41) pages Firefox hang with very low cpu on some sites.
    Firefox itself is not hung, but for this tab, the indicator of the clock continues ticking.
    I open the problem while another tab has the problem.
    Some data on the website are generally displayed (context?).
    There may be a redirect/refresh any (full proposal).
    Note: in this case, the web site is grayed out.
    Example: https://www.code42.com/store/
    Problem is when I navigated to the URL above. Also occurred when I pasted the URL.
    Works in Version Chrome 45.0.2454.101 m.
    Working on board 20.10240.16384.0

    Note: right now, I'm trying to upload an image, the download is not finished. Ticks of the clock.

    I will try to present this anyway.

    I was about to follow the instructions in the above message, but tried the web site to verify that the problem continues. There can be no. I don't know what I've done (maybe I cleared the cache I've been poking).
    Anyway. Please close this incident.
    And thanks for your help.
