Safari web content to 99% of the CPU

Sometimes, my Macbook Air start at full speed of heat fan just because I have Safari open. If I close the fan falls down.

You have any idea why this is happening?

It would depend on which Web site you are browsing. If it is a site that is not necessarily very dependent on intensive graphics or videos, this kind of CPU usage would be unusual.

aAlso remember that modern computing devices use multiple processors, same numbers greater than 100% are not atypical.

  • Make Firefox preserves web content already loaded when the Tablet is paused

    I recently had an Android Tablet and loaded Firefox on it as my browser. First of all, I intend to use it for reading web content, sometimes when offline - i.e., I would like to be able to load some websites at home, leave Firefox open and put to sleep (NOT turn off), go somewhere where I don't have wifi, then wake the Tablet and read my sites loaded - just like I do with my laptop but much more portable.

    The problem is that it seems that when I do this and go in Firefox after the awakening of my tablet, the browser seems to always reload the Web page from scratch. It is a pain because it means that I have a wifi access to read Web pages and I often partially through a post very long blog/forum or something similar, and I spend a lot of time scrolling to where I was.

    Anyone know why this is happening and what I need to do to get Firefox to just keep the content I have already loaded?

    OK, tried this today and it worked fine. I don't know what happened yesterday. Close this question!

  • Safari Web Content & Flash Player does not

    Safari is badly hung on my iMac 2011 and I'm using version 9.1.2 (11601.7.7)

    I have 20 GB of physical ram.

    Looking at activity monitor, I regularly see that both Web safari & or flash player (internet safari plugin) (not answer) in red.

    Physical memory is sometimes heavily exhausted and then calms down when I shut safari. I tend to keep a number of tabs open in safari, because that's the way I run my business.

    I checked that adobe flash player is up to date and works well.

    All the boxes are checked in Safari preferences under Security and "Allow" is in place for Adobe Flash Player etc.

    I cleared my history and cookies.

    Can anyone advise what I can do?

    Thank you

  • When scrolling through web content, screen jumps to the first page after a few seconds, how do I solve this problem?

    This problem just happened while looking through the Mozillza support site.

    while scrolling (two finger or with scroll bar) , after a few,(3-5) seconds, the display jumps to the top of the page.
    

    I only have usually a website open at a time and this was the case during this most recent event.
    Please, couch answers in simplest terms as I am old and unfamiliar with techspeak. Thank you!

    Have you noticed any other unusual behavior?

  • MBP overheating on surfing the web (content web safari 100)

    Hello..

    You can have a Safari extension or the third party plugin installed which is causing a conflict. It is easy to solve the problems.

    In the Safari menu, click Safari > Preferences , and select the tab ' Extensions '. If there are installed extensions, one at a time uninstall and exit then restart Safari to test.

    If it is not a question of extensions, try troubleshooting third-party plug-ins.

    Back to Safari > Preferences. This time select the tab Security Deselect: plug-ins Allow. Quit and restart Safari to test.

  • Adobe for Web content viewer can display of only 1 article in a folio?

  • Canvas page view tab on Web content in Forms 6i

    Forms [32 bit] Version 6.0.8.8.0 (Production)

    I have an existing form that has several paintings and there are two or three fields on Web content and then on the same content on a canvas of the tab is scheduled. I can see the two paintings in the same page layout editor and select move the canvas of the tab.

    But when I create a new form and want to provision a canvas on top of content tab, it appears in an editor window of separate provision on the design time.

    I want to it as below:
    -----------content--------------------
    |                                       |
    |                                       |
    |                                       |
    -----------------------------------------
    |TabPag1     TabPage2                   |
    -------------      ----------------------
    |                                       |
    |                                       |
    |                                       |
    |                                       |
    |                                       |
    |                                       |
    -------------content------------------
    How can I create it so that it appears in the same window of the page at design time editor and appears in the same window as a canvas over time.

    The canvas of tabs to display on the table of contents in the layout editor, it actually takes to pull the canvas with the table of Contents tab; for example: open your table of contents in the layout editor, click on the button of toolbar tabbed canvas and then draw it on your table of contents. If you create the canvas through the Navigator object tabs object and then set the properties so it would display on the table of content - it is not visible on the table of content with the layout editor.

    This is a bit of an oddity in the form designer, and they have not corrected in newer versions of the forms again. :-(

    Hope this helps,

  • CPU usage and Mail Web Content

    I had a problem with macOS Sierra and Safari 10 where the CPU load for any tab was about 140% and the spinning fans, this was resolved by disabling Trusteer report. However, I still have a running process 'Mail content Web' running at 199% and fans of loading up every so often. Is this normal (seems a bit high) or is there something else I should disable/enable?

    Thank you

    Thank you.

    Hello DZanvettor,

    Thank you for using communities of Apple Support.

    If I understand your message that nothing happens when you try to remove the Safari Web site data. I know how it is important for you to be able to remove the Safari Web site data. I recommend that you restart your Mac into safe mode and see if you can remove the data from the Web site in secure mode.

    Here are the steps to restart your Mac in safe mode:

    Safe mode (sometimes called secure boot) is a way to start up your Mac so that it performs certain checks and prevents certain software from loading automatically or opening.

    From your Mac in safe mode does the following:

    * Check your startup disk and attempts to fix problems if necessary directory
    * Loads only required kernel extensions
    * Prevents the elements start and the login items open automatically
    * Disables installed user fonts
    * Delete font caches, hiding the kernel and other files of the system cache
    * Together, these changes can help resolve or isolate issues related to your startup disk.

    Follow these steps to start in safe mode.

    1. start or restart your Mac.
    2. as soon as you hear the startup tone, hold down the SHIFT key.
    3. release the SHIFT key when you see the Apple logo appears on the screen.

    After you delete data from the Web site in safe mode restart your Mac and allow it to start up as usual. Then test the issue again.

    Best regards.

  • Firefox not to honor the "Offline Web content and data user" settings

    Firefox still accept web content offline and the user data, I have never any notification regardless of the 'tell me when a website asks to store data for use in offline mode' parameter (in preferences > advanced > network).

    I also completely erased all: permissions tab regardless of the "all sites > offline storage" storage offline implementation is always allowed.

    Here is one - step by step to reproduce my problem.
    1. make sure all: permissions is clear
    2 make sure that the list to: Preferences > network > "the following Web sites are..." "is that clear
    3. close the preferences window
    4 go to go to http://appcachefacts.info/demo/ ... No notification about the offline cache will appear.
    5. open the preferences, the list of preferences > network > "the following Web sites are..." »
    Will fill up now with http://appcachefacts.info (1.1 MB)

    This article list persists even after closing the browser window and re - open.
    This happens with a total disregard for the settings described in the first paragraph.

    I found a related question, but it's old and archived:
    https://support.Mozilla.org/he/questions/981189

    Firefox will store small amounts (less than 50 MB) of data without asking permission.

    • offline - apps.allow_by_default; true
    • offline - apps.quota.warn; 51200

    You can switch the pref in offline mode - apps.allow_by_default to false to make Firefox ask.
