Hi 1slcs

This looks like an issue with your graphics display driver, in this case an out-of-memory crashe where all available memory is used up.

Did you try to disable hardware acceleration in Firefox?

Yes, this crash has already appeared after disable acceleration! Problems with the video card can not be, in other applications, and in the opera's okay! As can be consumed memory if I have her 4 GB? or is the memory allocated to the needs of Mozilla? ITS should be increased?

Does Firefox crash often?

Are there also plugins active when this happens?

You can try to run Firefox in Safe Mode for a while to see if the crashes still happen.

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

I said that he knocked the previous profile completely,cleaned the registry! established a new Firefox,all settings are default,no add-ons and plug-in I have not installed! And still Crashes continue!Here for the last 2 days - 2 crash! understand what's going on! I also noticed that the crash occur when open a lot of pages!

Start your Computer in safe mode. Then start Firefox and see if there is any change.

not a very good idea , because of the fall occur about once a day! all this time is in safe mode I can't!Can there are other any suggestions?just don't want to use another Browser, as it is very accustomed to Mozilla!

Not Firefox, The Computer.

I meant the computer!In a safe mode to sit not the option, especially to wait crash! Problem obviously in the Browser if it on default settings falls! In other appendices and programs of problems isn't present, including the browser the Opera!

Please note that disabling Firefox's use of hardware acceleration is a workaround for Firefox being incompatible in some way with your graphics card driver software. The problem is that these incompatibilities are not always recognized and fixed in testing due to the wide range of cards and driver versions in use. And also, of course, many users aren't interested in suffering and reporting repeated crashes, so they just disable Firefox from using hardware acceleration. So if you want to call it a problem in Firefox's default settings, that's fine: our mission is to get Firefox working on your computer and that may require some changes to the defaults.

The new crash report says OOM or out-of-memory. This doesn't mean that Firefox used all of the memory in the computer, but the memory allocated for the task/function was exceeded. Likely this is related to the content that Firefox was trying to render at that time.

During the past week, it appears that this particular crash signature has been reported over 100,000 times with over 2000 user comments. ("More Reports") I think the more relevant thing would be the circumstances under which you encountered this problem. Other than having 40-50 tabs open, can you recall what types of content you were loading or scrolling through at the time?

Thanks for the help! But here that I will tell! The videocard rather new GTX660 - Ti, drivers the last so problems are excluded, in other programs and appendices everything works like clock-work, including in the Browser the Opera, so a problem in Mozilla! Developers do nothing what to eliminate this problem! Into the memory account at me its 4 Gb and at the last more crash, at 40 open tabs, about 1,6 Gb were involved by the Browser, all in system about 1,5 GB free! Or it was shortage of memory of Mozilla allocated under needs? how to increase it?Tabs were open different, multiple tabs Youtube! Waiting for your advice!

If Youtube is involved, consider some troubleshooting for the Flash player plugin. For example:

(1) Disable the protected mode feature

This involves creating or editing a settings file. You can disable that by creating or editing a settings file. The following pages/posts provide different ways to do that:

• Adobe support article under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

• Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209

• Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078

Flash needs to completely unload from memory (exiting and starting Firefox up again might help) before this takes effect.

(2) Disable the plugin from using hardware acceleration

See this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

Did as you said but a memory problem was not solved!But the crash also no ,I now don't open many tabs! Wanted to ask how to increase the memory for the needs of Firefox? Now installed the Nightly build,I'll try it!

Do you have any recent crash reports?

If you do not like crashes, I think you should not install Nightly. It is the least tested code available.
