Why does firefox randomly close (no crash report appaears after)?

Firefox randomly just closes on me. It's not a crash, at least not a normal crash, because the Crash Report does not come up. It's just one moment it is open and the next it is now.
On top of that when it does do this, and at random other times as well, I am not able to re-open it for several minutes or I have to close the actual process through task manager in order for it to open again.

I'm sorry but I think you didn't get the problem right. Firefox just unexpectedly closes. It does not crash. There are no crash reports.

Why does Firefox continually close itself without warning, but reopen prior tabs, without an error message or crash report?

For the past couple weeks Firefox has been randomly closing itself, without warning. I will be on another program on my laptop and Firefox will shut down. But, when I reopen it, all my tabs will restore as if nothing happened, and there is rarely a recovery error alert. I also do not receive crash reports for this phenomenon. Everything about the browser seems to be working fine as usual otherwise.

Why does Firefox 21 close first session every single day?

My girlfriend has a new Vaio laptop running Windows 8 and Firefox 21.
Every time she starts Firefox for the first time (after powering up the laptop), the browser closes immediately upon her selecting a bookmark from the bookmark toolbar (usually Gmail) or whatever the first task is that she asks Firefox to do for her. (i.e., search or open a URL.)
I've already reset Firefox and confirmed that hardware acceleration is NOT enabled. (We've replicated the problem after completing these steps.)
The last four crash reports are below.

Needless to say, this ongoing problem is very frustrating. Any suggestions on how we can make her browser work more reliably would be greatly appreciated.
Thank you!

hello, i think the crash might be triggered by Whitesky's ID Vault which is installed on the notebook...

Why does Firefox randomly disconnect my tabbed windows into their own window?

I use tabbed browsing in my Firefox, since up grading to Firefox 18 it will occasionally, at random, disconnect a tab from the group. There doesn't seem to be a pattern and I am not telling it to separate the tab from the group.

Hi DHarbour60, 
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
 
To Reset Firefox do the following:
 
* Go to Firefox > Help > Troubleshooting Information.
* Click the "Reset Firefox" button.
* Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
* Bulleted list itemFirefox will open with all factory defaults applied.
 
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Why does the checkmark for "Submit crash reports" in System Defaults always reappear after I remove it?

I keep trying to remove this check, but it always come back on its own.

Thank you for the reply, but none of those suggestions apply/or work. This is only a single preference that's not being saved. There is not a user.js file, but a prefs.js file and there is not an entry for crash reports on/off in it. These seems like a bug in Firefox, as the checkbox for the "Submit crash report" toggles back on the instant the dialog is closed, then reopened. In other words, just this one option is not saved. Any other options are saved when changed.

Why does Firefox 28.0 keep crashing and opening up random tabs?

I'm running Firefox 28.0 on a Windows 8.1 laptop. Recently, it began opening up random tabs to spam websites and it's SUPER annoying. Then, the other day it began to do this thing where it'll stop responding. Rather than just freezing up for a second like it used to, it won't unfreeze and I have to restart Firefox. I reset Firefox today, and that didn't solve any of my problems.
System specs;
OS: Windows 8.1
Processor: Intel(R) Core(TM) i3-3227U CPU @ 1.90GHz 1.90 GHz
Installed memory (RAM): 6.00 GB (5.88 GB usable)
System type: 64-bit Operating System, x64-based processor
Pen and Touch: Pen Support
Windows is activated

I've already done this, and it says nothing is wrong with my system.

Why does Firefox 35.0.1 crash regularly on many sites that use javascript image rotation?

Since the latest update to version 35, many sites that use javascript to manipulate images tend to crash firefox and make either the guilty tab or all of firefox close suddenly. (Firefox on Debian 7 Wheezy Linux, all updates current). I use firefox daily for web development and this regression bug is VERY annoying for my workflow. I understand you cannot take every situation into account. I do not have the time to investigate what has made Firefox less stable. I really hope you can fix this performance problem. If I can do anything concrete to help besides jumping into the code, let me know.

Why does Firefox 8 close unexpectedly after I print a webpage?

I use Windows XP and Firefox 8. When I print a webpage, Firfox closes and has to be re-opened. No messages are received.

Thanks. I have just restarted Firefox in safe mode and printed a webpage without Firefox closing. Will this affect any other use of Firefox?

Why does Firefox 4 for mac crash when attempting to manage add-ons?

Downloaded firefox 4 for mac yesterday. Working fine until I started adding add-ons/extensions. Since then, any attempt to manage add-ons or extensions crashes Firefox and requires a force quit.
Help?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
Delete the files extensions.* (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar to do a compatibility check.

Why does firefox 7 crashes the system if Quadro NVS 135M graphics driver is installed?

Why does firefox 7 crashes the system with a Quadro NVS 135M graphics cards installed?
It happens immediately after opening Firefox on a two screen system. You get a message saying the Graphics Driver stopped responding, but that it managed to recover, but after a while the system freezes completely. You can't even CTRL+ALT+DEL.

I get this too on with my nVidia GTX460 card. In my case the screen goes black. It happens once every few days, and for a while I could not figure out why. I was forcing a shutdown to get the screen back.
But I put the computer to sleep and woke it up, since that restarts the video, and this let me see what was wrong. The only error message is it reports that Firefox hung. There is nothing else in the Event logs.
I'm running Windows 7 with all the updates from Windows Update, and my video driver is 285.62, but his also happened with the 260.26 driver.
I imagine this is happening a lot, but people aren't able to isolate the cause.
I'm looking for a fix, not a bypass.

My firefox always opens a crash report when I close it. Even if I have no tabs open and close firefox.

Why does Firefox Crash Constantly?

Like others who have reported this issue, Firefox has been crashing constantly on numerous different websites. I have Windows 7 32bit which was recently re-installed, fully updated. All drivers are up to date, all add-ons are updated, all plug-ins are up to date and in fact, I've disabled most of them and yet, the crashing continues. Looking at the crash reports, it seems to be related to Java "'''''Firefox 7.0.1 Crash Report [@ js::mjit::EnterMethodJIT(JSContext*, js::StackFrame*, void*, js::Value*) ]'''''"
This has been an ongoing problem since FF4 and I have since resorted back to a portable version of FF3.6. I've been through all the troubleshooting steps included on this website. My computer is clean of any viruses, malware, spyware, etc. Starting in safe mode seems to be to only solution to this problem but completely defeats the purpose as to why I'm using it in the first place. Looking at the crash reports, it seems this is a known issue with FF:
https://bugzilla.mozilla.org/show_bug.cgi?id=595351
I've been a long time user of FF but if this continues to happen, I feel the the only solution will be to switch to a more stable browser until this is fixed. If there's anyone out there, please help find a solution to this problem. It's been ongoing for far too long!

OK I knewwww I shouldve waited a little longer. A few seconds after posting my last reply, the flash player crashed on Firefox. This is an additional problem that happens constantly on FF. I know there was something about some conflicts between the flash player with FF & some other flash player....but i'm not totally sure what it is & how it all works.
Plus it seems like that is something I've already gone in & tinkered with.
(I originally wrote tinkled with but then caught myself)
