After you download the new version of firefox, I didn't like it and tried to restore my system to an earlier time and version of firefox. Now that firefox does not open, even the old version isn't there more.

I want to get firefox, keeping all bookmarks.

Download a new copy of Firefox and save the file to the desktop.

Uninstall your current version of Firefox.

  • Do not remove the data of a personal nature when you uninstall the current version or you lose your bookmarks and other data in the profile folder.

Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

  • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.

Your bookmarks and other profile data stored in the Firefox profile folder and will not be affected by a relocation, but make sure that you do not select delete data of a personal nature if you uninstall Firefox.

    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.

  • Firefox does not open after the update. Cannot open the profile technical, even when you use the directory in cmd line path

    I'm using Firefox on a Windows 7 computer. Firefox does not open after the last update. I read the help articles and it seems that I need to create a new profile because my settings were probably corrupted. I'm unable to open the profile technical, even when you use the directory in cmd line path. I tried the following commands in the command line:

    Firefox Pei
    "C:\Program Files (x 86) \Mozilla" PEI

    Nothing happens with every order.

    I am also running Norton Internet Security. I read a help of virtual navigation features Re article that can cause a problem. The article says to check the setting of virtualization in the internet security software and to clear the virtual cache. I went through all the menus of settings in Norton Internet Security version 21.6.0.32 and I don't see anything that looked like in "virtualization" settings, so I guess that does not apply to me. "

  • Firefox does not open. Hangs during 'connection '. Inadmissible even in the process of closing via the Task Manager.

    Yesterday, Firefox does not open. It hangs at the "stage of connection." For hours. It doesn't even turn off using the Manager of tasks for applications or processes, and it hangs almost all other applications. I thought that I managed to save a Word document opened yesterday - it looked like a slow, but normal save during the shot of Firefox, but the document was empty when I restarted my computer.

    Although my machine is not pentium 4 in service, I tried to start by using the configuration of Windows XP/M, I downloaded and re-installed (above) the existing version, I checked that no process of Mozilla turned before trying to start Mozilla and tried to create a new profile. Absolutely no success. Every time (dozens), I tried to start Firefox, I had to force a difficult to exit the application shutdown. I now have this marking Firefox in my taskbar, because I keep forgetting and hit by reflex.

    I am running version 11.0 (at least that's what I just downloaded - I am not positive of what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3 2.4 gHz, 4 GB of RAM, 64 bit OS.

    Next option is to restore to an earlier version. If this does not work, I uninstall and start again from scratch.

    I disabled AVG (antivirus free 2012) for 10 minutes, open Firefox and browsed a bit. Close the browser, whereas the temporarily disabled AVG activated itself again and restarted Firefox. Now, it connects perfectly - several times faster than prior to this incident (I have installed v 12.0; previous version was 11.0). I use the Microsoft Firewall, if while the firewall solution suggested above has not worked, he put me on the right track.

  • After you download the update of Firefox 25.0.1 Firefox does not open. Help! Thank you!

    I downloaded the update for 25.0.1 and he ran. Instead of restarting, I stop the laptop (Vista Home SP2, 64-bit).
    When I started the laptop again, I tried to open Firefox, but Norton Internet Security leader Insight could not check the update as a reliable file and did not allow for Firefox open.
    I tried to disable file Insight but got the same results.
    I ran Live Update to update Norton Internet Security and then tried to open Firefox again.
    This time this Norton Internet Security displays a message saying that updater.exe wasn't careful and eliminated.
    When I try to open Firefox, Norton now detects Updater 25.0.0.5046, said he trusted, but Firefox does not open.
    I want to save the history if possible.
    How can I get Firefox to work with recorded history again?
    Thank you!

    Hi iamjayakumars - I was not able to create a new profile, because the Profile Manager does not open. A message from Norton seems "Updater.exe is sure.", but nothing else would happen.
    But - the links you sent were very helpful, and I was able to solve the problem by making a UN-installing and then re - install Firefox:
    1. backup of the profile.
    2. download the installer of Firefox from Mozilla.org with another browser.
    3. un-install Firefox from the control panel (ensuring "Delete my personal Firefox and customizations data" was NOT selected.)
    4 reinstall Firefox.
    Firefox starts successfully with all my old settings and all the tabs I had open the last time it was used appeared as I had hoped.
    Thanks a lot for your help!

    In the last week or two, for reasons not clear to me, Firefox does not open the new links after the first; It is used to open a new connection in new tabs (according to my preference) without problems in the past. Now it does not blink again.

    Over time, I've added new applications and others removed, and, of course, I can't exclude from their role in the problem that I have now. I would appreciate some help to solve this problem.

  • Firefox does not open, and when I try to use the "run", it says that the file has been moved, etc. I use Windows 8 and I can't lose my favorites. Help?

    Firefox has been great to work on my computer for months and then suddenly he could not load pages. So, naturally, I restarted my computer, but when it restarted Firefox does not open. The icon lights for a bit as usual, then it fades and never actually opens. When I try to use the "run" command, I get this error:
    "C:\Program Files\Mozilla Firefox\ refers to a location that is unavailable. It could be on a hard drive on this computer or on a network. Make sure that the disc is inserted correctly, or that you are connected to the Internet or your network, and then try again. If it can't be located, the information may have been moved to another location. »
    I also tried the same thing for the file in the x 86 folder, but it gave the same error and I went and looked for the files in the given location and they were there.
    Firefox is not to fall down, so he isn't there an other error message, I can give you.
    The things that I had my favorites are really important, I can not lose those, but I am fine with anything else have to re-installed, etc..
    Help please?

    I've never tried it myself, but the forum has a series of measures for a "clean reinstall" Firefox. Even if you do not delete the record of your personal settings (AKA profile) during this process, a backup of this folder is always a good idea in case something goes wrong.

    Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
    2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    Please report back to see if this helped you!

  • Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox window is sometimes "off screen" somehow. Often, you can force it to appear on the screen by right clicking on the thumbnail image just above the taskbar and choose expand. Does it work?

    A possible cause for this is that the file that stores the positions and sizes of window is corrupt. You can delete this file and Firefox will return to standard window resizing.

    #1 method: If you can get a zoomed window:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    Pause while Firefox finishing its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    #2 method: If you can not get a Firefox window for all:

    Close Firefox by right clicking the icon in the taskbar > close all windows.

    Using the Run dialog box (windows key + R) or the start search bar menu type or paste the following and press Enter to drill down to the profiles folder:

    %APPDATA%\Mozilla\Firefox\Profiles

    Here you can see a folder - in this case, double-click that - or more than one case - in this case, double-click on in what looks like the most recently updated.

    Scroll down and rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    Then, to re - light bars, you can use one of the following methods to view the list of the toolbar, and then select the desired bars it:

    To activate the menu bar, toolbar bookmarks or other bars, click it in the list.
