Attempting to open Firefox freezes computer, requiring system shutdown via On/Off button. Opening FF in Safe Mode doesn't help anything.

I was using Firefox just fine as I have been for years, and when I tried to open it today after restarting the machine, it froze the computer almost completely (mouse works, but clicking it anywhere does nothing and ctrl + alt + del does not work). Sometimes even the mouse ceases to work. The only way to react to this is to shut down the system by cutting the energy (On/Off button) as I have waited up to 5 minutes and the system does not recover.
I have tried opening the Safe Mode dialog box (start -> run -> firefox -safe-mode) and choosing the options to disable extensions and toolbars and "reset user preferences to FF defaults" and click "apply and restart" and the computer freezes. If I hit the "continue with Safe Mode" button instead, I get to see the FF screen with a blank tab on it but the computer freezes as well.
I am completely baffled by this sudden problem. I am having to type this from Google Chrome and thus I cannot supply troubleshooting information, sadly. I am sure it is not conflict with antiviruses because I have not installed any new firewalls or antiviruses before the problem started.
I tried downloading Firefox 8.0 and installing it (was previously on 7.0) but it didn't help at all. I also tried running FF with Windows on Safe Mode, but the freeze still happens.
Please help me, my life depends on ReminderFox reminding me of stuff and now I can't access it :,-(. I need FF back ASAP!
Thanks a whole lot!
'''Addendum:''' The freeze is also happening at random even without opening Firefox, it has a chance of happening when I click something. My computer has frozen when I: 1- clicked the "reveal desktop" button to minimize all windows; 2- Attempted to close a tab in Chrome; 3- Clicked "play" in a Youtube video that had been loaded and waiting for some time). It will also almost always freeze when I leave it idle for more than about 10 minutes.
But it will '''guaranteedly''' freeze when trying to open FF, which doesn't happen with any other program.
I think my computer is breaking down. :(

  • I reset Firefox. Now when I click on the icon to open Firefox my computer asks me if I want to let Firefox make changes to my computer.

    I reset Firefox. Now when I click on the icon to open Firefox my computer asks me if I want to let Firefox make changes to my computer.
    I have read that I should do a clean reinstall. Will I loose all of my open tabs, bookmarks, history etc?
    Is there another way to fix the problem other than a reinstall. this would have to be my last resort!

    A possible cause of this error is that Firefox is set to run as Administrator.
    Check that Firefox isn't set to run as Administrator.
    Right-click the Firefox desktop shortcut and choose "Properties".
    Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
    * Privilege Level: "Run this program as Administrator" should not be selected
    * "Run this program in compatibility mode for:" should not be selected
    Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).

  • Why, when I open Firefox 9.01 do I get a message that I do not have the latest version when Help-About Firefox says I do?

    There are/were three problems:
    '''1.''' Why, when I open Firefox 9.01 do I get a message that I do not have the latest version when '''Help>About''' Firefox says I do?
    '''2.''' Also, with the 8.xx version, I was unable to open in a new window with a right click until I upgraded to 9.01. (Old problem now, but I am curious.)
    '''3.''' When I tried to uninstall the older version the uninstaller told me that I had to close the open version, but it was closed according to my taskbar. I also have this problem with Thunderbird.

    1. You are using the latest version which is Firefox 9.0.1
    From your description it sounds as if you may still have the old http://www.google.com/firefox Firefox start page hosted by Google as your homepage. This old default homepage is no longer used as '''about:home''' has been in use since Firefox 4.0
    Either ignore the message, change homepage to '''about:home''', change it to another page or leave blank.

    Hello,
    It isn't the fw in Network you want o use or look at, that's for something completely different.
    My first suspect is the Power Adapter on the LaCie has gone.
    At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware>Firewire, what is listed there?
    Reset the Firewire bus
    If your Firewire or USB isn't recognizing any device.  A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
    1. Shut the machine down.
    2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.
    3. leave it for 10 minutes.
    4. Connect back up and reboot.

  • Occasionally (but not always), opening Firefox freezes/crashes my entire system. Why is this? Win7 64bit

    Every few uses of Firefox, I click the icon to open the program, and my system freezes. Ctrl+Alt+Delete does nothing, Ctrl+Shift+Esc does nothing. The mouse won't move, keyboard non-functioning. I have to do a hard reset of my system (hold power button until it shuts off, restart). No crash report is generated/shown/submitted, probably because my computer freezes before Firefox can even open.
    This does not happen with any other program, only Firefox. Running Windows 7 64-bit.
    I have to fill out this form on Internet Explorer, because now after restarting my computer firefox won't open at all, regardless of which icon i click.

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • Whenever a new window (or even Firefox program windows like Add-ons, Bookmarks, Settings, etc) is opened, Firefox freezes for 30+ seconds before opening it.

    I have reset Firefox, then reinstalled, removed all of the extensions and plugins, uninstalled and reinstalled Flashplayer, updated Java, etc. I have also created new profiles, which have the same problem.
    The problem does not appear in Safe Mode, which is odd because I have disabled all of the built-in extensions and have run the program in regular mode, and the problem still occurs. Right now I am using no extensions, no plugins, and no themes, and Firefox still freezes for a short period of time whenever I try to open a new window.
    This problem does not happen in IE or Chrome. I have not installed any programs recently; the problem started happening randomly.

    Hi,
    [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode] also disables the themes ('''Appearance''') in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''. and hardware acceleration - the manual setting is '''Tools''' > '''Options''' > [https://support.mozilla.org/en-US/kb/Options%20window%20-%20Advanced%20panel?as=u Advanced] > '''General''' > '''Use hardware acceleration when available'''. All these settings/options/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if a theme, or hardware acceleration is causing issues. Disabling/enabling hardware acceleration, and some types of add-ons in normal mode may require a Firefox restart - a quick way to restart Firefox is to press [https://developer.mozilla.org/en-US/docs/Tools/GCLI '''Shift''' + '''F2'''], type '''restart''' and '''Enter'''.

  • When I go to open Firefox, my computer goes to a blue screen, and says my computer is shutting down because of a potential risk, do you have any way I can solve this?

    So just like I said, when i go to open firefox, the screen goes blue, and says that my computer is at risk. This is the only problem it happens to, I have tried uninstalling and re stalling the program and nothing seems to work. I really like firefox, and the features it has. If you could please help me with this problem

    That seems very suspicious. Two suggestions.
    First, try Firefox's Safe Mode. This will let you work around problems with add-ons and perhaps help you identify things to remove so that Firefox goes back to normal.
    I recommend making a backup of your Firefox settings before starting in Safe Mode. To back up Firefox, see [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].
    Next, try starting Firefox in Firefox
    [http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up.
    Does that work? If so, you may need to disable your add-ons and just bring the most essential ones back to life until you discover the problem one.
    Second thought: malware. You could supplement your usual security scans with these:
    Malwarebytes Anti-malware : http://www.malwarebytes.org/mbam.php
    SUPERAntiSpyware : http://www.superantispyware.com/
    HouseCall : http://housecall.trendmicro.com/
    Hope this helps.

  • Firefox freezes up for 2 full minutes, every time I open it.

    After I open Firefox, I have about two or three minutes to browse around before it freezes up. I get the "not responding" message. This lasts for a full two minutes, at least. There's always time to pop open IE or Chrome and get the information I need, but usually wait it out.
    It is this, and the fact that I am asked to load new Java updates and restart Firefox EVERY TIME I open the browser that is leading me toward switching to Chrome. Firefox used to be the better alternative, now I get more reliability out of every other browser I use.

  • Firefox freezes temporarily when I click on a tab, then opens that tab in a new window instead.

    I thought it was related to a specific website but then noticed it happening on others. The browser freezes and then opens whatever tab I'm on in a new window instead. It's quite annoying.

    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).<br />
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]<br />
    <br />
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.<br />
    You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.<br />
    You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")<br />
    Your plugins list shows outdated plugin(s) with known security and stability risks.
