Firefox Support Forum

After upgrading to 3.6.4 the browser will not open. The process starts, but a window never appears.

Firefox will not open in Safe Mode. Profile Manager will not open.

Have performed a complete uninstall/reinstall, removing both the program files\mozilla folder and the mozilla folder in %appdata% before reinstalling.

Uninstalled all security software (MS Essentials, Outpost) and attempted reinstalling with no security software installed at all.

Have installed other builds, including Minefield and Namoroka. No 32 bit builds 3.6.4 or later will open on my system. The problem does not exist with 64 bit builds.

I have reverted to 3.6.3 but do not want to be stuck on this version forever.

This is the 3rd message on this problem. I can't do my finances if firefox crashes every time i try to access my bank account. I loved your product----until now. I rum OS X 10.6.4

Every now and then, when I'm on Firefox it will not respond then the window will fill white and at the top it will say "Mozilla Firefox (Not Responding)".

It responds after about 10-15 seconds but this keeps happening every 2-3 Minutes and is making Firefox unusable to watch videos on Youtube and read other things as when it starts responding it take me back to the top of the page.

I cannot pinpoint which websites this is on but it normally (But not always) happens when I have more than one tab open (Usually on Youtube + SammyServers.com)

I have recently updated my Firefox to the 3.6.4 version but every time that I try to open it, it loads but freezes and all I can do is close it. I've uninstalled and reinstalled but this has failed to help.

Operating system

VISTA 2 service pack

FF keeps crashing - script errors on pretty much every site. Reset FF and it does no good. Add ons disabled, all extensions updated. This just started happening within the past few days. No viruses. HELP!!!!!!!!!

Hello There. To my utter dismay I am forced to use Chrome to access this forum. The reason is the moment I use Firefox (3) my computer crashes and I get the dreaded windows blue screen. I have been using ff for a long time now without problems. Yesterday I updated adobe flash player, but have now uninstalled flash player in the hope that the problem is resolved. No luck. I can use my computer in normal manner without problems, but the moment I use ff it crashes

I updated to Firefox 4 on my vista laptop. I am running no redirect and a script blocker, both compatable with firefox 4. Firefox 4 keeps crashing, will keep loading the "well this is embarrassing" page, even when it starts normally, I will load a page, and within a few minutes, firefox will redirect to that page, then crash

Gave in to the "nag" screen earlier this evening and "upgraded" to Firefox 14.0.1 from 13.0.1

And since then I've had multiple "not responding" problems. Just hangs, repeatedly. Whether I'm doing anything or not. On a variety of websites - planet-f1.com, bbc.co.uk, youtube (seems worst on youtube), facebook... pretty much anything I do. It's even hung on this page once. All I get is the "circle of doom", the "not responding" top of screen, and eventually the "whitewash of death" look.

I've disabled all my add-ons (not that I had many, mainly just adblock and flash) but no avail. Cleared cache and cookies.

Seriously tempted to go back to 13! Any other ideas?

I tried everything. Deleting cookies. Un installing and re installing adobe flash. I tried the suggestions listed on the firefox site Adobe flash works fine when I open google chrome. Why does firefox suck? Its ridiculous... Its so bad...

I am facing this prob for the last few days...It says firefox encountered a prob and needs to close down....After a lot of findings I came to know that it was due to Adobe Flash Player ...when this plug-in is enabled and i visit video sites firefox crashes, but if I disable this plug-in firefox doesnt crash.....Please Help... I dont want to switch to other Browsers..:(

firefox hangs after last updates regularly, after closing down with task manger the msg "plugin container for firefox stopped working" appears. other problem after last update occurs when i open firefox - nearly always it shows the msg "Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page." No matter if I open firefox completely new or if I do it after closing down via task manager. (virus scan is running on a daily and detailed on a weekly basis)

Since I updated to Firefox 5, my computer freezes all the time. Can I get Firefox 4 again? Everywhere I see a download for 4 it is actually 5. Also if I can't have my Google tool bar, I don't want Firefox at all.

It seems that since the automatic update from Firefox 14.0.1 to Firefox 15.0, the browser works normally when viewing pages containing Adobe Flash elements, but crashes when I close the Firefox window. Apparently the browser exits normally but one or two seconds later, Windows reports that Firefox has stopped working and the crash details indicate there was a problem with xul.dll.

This happens randomly, not systematically. But in all cases, it was after some Flash content was loaded. It never happened with Firefox 14 nor any previous versions, and Flash 11.4 was installed before the automatic Firefox update.

Using Firefox 15.0, Flash 11.4.402.265 on Windows 7 SP1 64 bits.

Why can't firefox.exe be killed in Windows? I'm getting daily crashes in FF5, and jusding by thousands of posts so are others. I could live with these IF Windows allowed me to End Process, but it does not. I've even tried to end firefox.exe at the command line against the PID, but despite saying it had been teminated it has not. Having to close all my work and reboot Windows every time FF decides to longer work is VERY frustrating!!

Script quits working - this is when multiple tabs are open and I go to close one. First, I have to click to close the tab multiple times before it closes, then a 'new tab' opens on it's own. The script error reads Script: chrome://browser/content/tabbrowser.xml:1644 I have to then close the window, reopen it, and then all previous tabs open, and yet another 'new tab' opens. None of my tabs are closing with one click, all need two or more before they close. I love Firefox and have used for years, this really must be fixed.

In what seems like a relentless update/upgrade competition with the "other" browsers, Firefox 11 is NOW not playing nice with Shockwave Flash, or is it vice-versa. This didn't start happening until I "upgraded" to Firefox 11.0

YES, I've updated ALL the plugins (Who invented this plug-in hassle, anyway?), as is ABSOLUTELY required whenever Firefox goes through one of its myriad of updates/upgrades. I've uninstalled/reinstalled Flash, and my WinXP Pro is up-to-date. I haven't experienced this torrential headache with IE 8.0, OR before F-11.

Is there a Firefox 11.0.0.1.2.3.4 patch in-the-works, or do I have to consider one of the "others"? HELP ME!
