Firefox crashing and randomly closing itself..

Since last night, I've noticed that Firefox has randomly started closing at random points - it's not particular with any one website or anything, it just keeps either crashing or just randomly closing itself - and not allowing me to open up another browser until I end the process using Task Manager.
I was using an older version of the browser up until about an half an hour or so ago - I updated, hoping that it would fix the problem but have had no luck. I also tried running safe mode but the crashes occurred then too.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
* https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Ok, i change drivers to xf86-video-ati and also xorg to version 1.12. Everything seems to work fine, but now my graphic card is very hot.
It's a very big difference: 60 degrees for fglrx and 85 for open drivers. Very strange, temperature is much higher, but fan is much louder even if xorg is not running
I have to wait for new fglrx drivers...
Thanks

Firefox crashes and when attempting to launch after the crash it won't and throw and error msg that js.3250 can't be found- but same file is in Mozilla directory. I must then download new 3.6.8 and lose all tabs.

# Question
Firefox crashes and when attempting to launch after the crash it won't launch; throwing an error msg that " js.3250 can't be found" - but same file is in Mozilla directory.
I must then download new 3.6.8 and lose all tabs and history.

I have a similar problem. Recently my FF8 has been crashing a lot. It regularly locks up an entire core of my PC and often just shuts down. It has just done it a moment ago and when it started back up it did the whole "this is embarrassing" thing and asked me if I wanted to reload my tabs. I deselected the one that I was trying to view as I suspected that it may have been the cause (unlikely; it was node4.co.uk) but anyway, let's skip it just in case. Click on the button to restore and up pops my homepage only. So all of my other tabs, which I was using for work incidentally, are gone.
This is not the first time this has happened on FF8. It happened a lot recently on FF6 I think it was (so hard to keep track now, Mozilla) and I switched to Chrome as a result, but it turns out that it crashes even more than FF6 did. FF7 was a vast improvement but FF8 is so unstable/unpredictable for me at the moment that I think I'd rather use IE9 than this. It's driving me mental, clearly! I wish I could kill the process manually and have it retry restoring tabs. Hey, there's an idea Mozilla; give us a menu item that allows us to restore the session to how it started to try again or at the very least get a list of the pages we were looking at. They don't show up in Recently Closed Windows and the Restore Previous Session is greyed out too. Gah! Help!

Flash Builder 4.5 with Firefox - crashes and no performance data. How to fix?

I am an experienced Flex developer, but new to the Flash Builder 4.5 Profiler. I'm using Firefox 5.0 and Shockwave Flash 10.2.153.1. Windows XP.
I have several problems:
1) in the profile view during a run, the buttons are dimmed and therefore I cannot "Capture Performance Profile".
2) almost every time I run, the Flash Player in Firefox crashes (And now worse, using that same profile, Firefox crashes randomly, but quickly on ANY web pages. I smell a re-install of Firefox coming.)
3) there is the option to configure for the Standalone Flash Player and a browser. How do I say WHICH one to use for a given profile run?
If I configure the browser to be IE, Firefox runs anyway.
Any ideas? Suggestions? Thanks for the time.
Message was edited by: ozDiGennaro

I have solved the crash by reinstalling the latest Flash Player.
The configuration issue is not as important.
The solution was simple. In the "Profile" view, select the "[Running]" instance. This enables the important buttons, like "Capture".
This causes a "Performance Profile" line to appear, linked to the running instance. Double click to view the info.
Thanks for listening.

When firefox crashes and reopens it offers to restore pages hours/days old.

When firefox crashes and is reopened, it usually brings up the pages that were open during the crash, but many times when firefox crashes, it will offer to restore pages that I did look at but that are hours/days old.
e.g.
I will be on youtube, facebook, my school website, and pandora. Firefox crashes. I reopen. Firefox offers to restore google search, my email, and wordpress, which I had looked at the night before.

Every time I place a bid on Ebay my firefox crashes and must be restarted.

Every time I place a bid on Ebay my firefox crashes and must be restarted. This is the only time this happens. It seems to be ok until I actually confirm the bid and within a second or two firefox crashes.

This is most likely caused by '''The Browser Highlighter''' add-on. Uninstall or disable this add-on from Tools -> Add-ons -> Extensions. You could also try finding an update for this extension.
See [[Uninstalling Extensions]] and https://support.mozilla.com/en-US/questions/682558
If that does not solve the problem:
Go to the address '''about:crashes''' and tell us your latest crash IDs. We can then look at the data specific to your crash and have a better idea of what is causing the problem.

Firefox crashed and after restarting, tabs i had open were gone and weren't in the history either. It didn't give me the option of restoring, how do i get them back?

Sorry , you probably can not get them back.
You may have bookmarked them, or have them as part of the History previously stored and still searchable, but unfortunately otherwise you are unlikely to get them back. Firefox does to a certain extent back up bookmarks automatically but not the history.
If you get problems with crashes see [[firefox crashes]]

Whenever IE tries to open, Firefox crashes, and cannot be reopened unti I restart the entire system.

Whenever I click on something that brings up IE (not the default!), Firefox crashes, and when I try to reopen it, a screen comes up that is supposed to let me reopen it, but it won't. I have to reboot the system in order to bring up Firefox again. Is there some trick to restarting Firefox after this crash?

After mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

after mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

See if this works for you.
Open up Tools > Options -> General and toggle the first preference - '''Allow Firefox Developer Edition and Firefox to run at the same time''' - to get back to your previous Aurora Profile. It will tell you to restart Firefox.
If there's a check-mark in the box for that pref it shows the Aurora Profile, if you remove that check-mark it shows the Developer Edition Profile.

Firefox crashes and all website pages loose their formatting and pictures, and links are broken

I’m currently running Firefox 18.0.1 on a 13” 2011 MacBook Pro 2.7 GHz Intel Core i7 with 8GB or RAM that is running OS X 10.8.2 Mountain Lion. I have been living with this problem for over a year and this same computer has had this problem while running OS X 10.7 and I think even 10.6. The problem also existed with earlier versions of Firefox including versions 17, 16, and possibly 15, it’s been so long I can’t remember.
The problem is that Firefox crashes (or something within Firefox crashes) and the screen “goes white” and by that I mean all the graphics and layout of a page like YouTube disappears and even though the links are there, none of them work. The page is just made up of text and broken links. Reloading the page does nothing so I have to close Firefox and restart it. (No reboot) On relaunch everything is back to normal and may last a few minutes, or it may crash again right away. Generally if I launch Firefox and use it and then go use some other programs, when I come back to Firefox it will then crash. Is this a Java problem? Is this a javascript problem? I really don’t know what it is but it has persisted through several operating systems and different versions of Firefox running on different operating systems. I’m stumped and can’t find anyone who’s ever seen this problem. Any help or clues would be greatly appreciated.
I should add that this problem is present on ALL webpages, not just one or a few. Safari works fine on the same machine and visiting the same websites. I have screen caps of the crashed pages but I don't know how to post them here.

It was enough help! I found Firefox does default to the last folder. My problem was created because I was uploading from a subfolder within my d:/temp directory and then deleting that folder. Since the subfolder was deleted Firefox could not go to the last folder and was defaulting to the Mozilla directory.

Whenever I open new tabs Firefox crashes and the browser window closes automatically.what will I do?

I am facing this problem since a month.I never faced this problem before.I always feel good to use Mozilla Firefox as my browser.I used to open multiple tabs in a same browser window.For example- in a tab I logged in to Facebook,at same time I might be downloading songs or something else or open another site in the other tab.It might be 2 or 3 tabs sometimes.But now a days,I am facing the problem whenever I open multiple tabs.Its unusual and so much annoying.The Firefox crashes and the browser window closes showing a messege to send an error report.Please Help me.
N.B. - I am using the Windows service pack 2.
RAM - 2 GB
Hard disk MEmory - 250 GB.

I had this same problem. Seems to be caused by the web developer tool bar FF extension (this started happening after a recent update to that extension). After disabling it, my FF is back to normal :)

Firefox crashes at random times

Hey, over the past couple of months Firefox for Windows (8.1) has been crashing more and more. There's no obvious reason for it that I can detect.
I'll just be browsing the Internet, reading an article or something and then it will suddenly just freeze. I'm not even able to ctrl-alt-del to shut it down manually, Firefox just freezes on me, and it's clear that it's struggling to process something as it occasionally will flicker a little as though it's trying hard, but it just stops. There's an outside chance it's my computer in general to blame, but it only ever seems to happen when I have Firefox open (and I don't always have Firefox open).
I have the most up-to-date version (37.0.2). Here's a few of the most recent crash logs:
bp-b5e763f2-f2a6-4b35-8856-f3e112150424
bp-f5b4bea4-9ec5-48ac-b70d-ece952150423
49a5259d-42b9-48cd-bf94-bc46695d3571
0042f953-ec91-4fed-90da-2a2e9e3b6aab
Most of these logs mean nothing to me, so happy for one of you smart guys to parse this for me. Thanks.

The only other situations I can find with this exact crash reason were problems with the computer itself or video drivers and not Firefox. This could be a corrupt RAM issue or a corrupt file system. It could also be a video card bug, since the crash is actually happening in the UI part of the program.
I would try 1. Testing your RAM, 2. Doing a file system check, and 3. Updating graphics drivers.
If any issues are found during any of those steps, I would fix the issue and then fully uninstall and re-install Firefox after fixing the issue.

I installed Firefox v. 3.6.15 on 3/21/2011. Since then Firefox crashes and closes completely when I click on certain e-mails in my inbox. How can I fix this?

I run v. 10.6.7 Mac OS X on my iMac. Java is v. 10.6, Update 4. My Adobe reader is v. 9.4.3. Clicking on random e-mails in my inbox causes Firefox to completely close. I get a window that says "Firefox quit unexpectedly". When I click on "Reopen" I get a window that says "Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page. There are no 'Crash ID(s), because my desktop goes back to the homepage because Firefox completely closes. Does anyone have instructions on how to correct this?
