My Firefox has been crashing a lot in the last few days. Just in the past hour it crashed 3 times already.

I also notice that Firefox is using a lot of RAM, and my computer asks me to close FF the whole time.

The ID of the latest crashes are.

I hope this can be solved, so I can keep using Firefox. I don't want to switch to another browser. Thank you!

Thank you for your replies! I ran a full scan of my system and there was one dangerous piece found. After that I reinstalled Firefox. I can already see that it uses way less RAM now. I suppose it's good now! Thank you a lot!

(I have it the right way round this time ! UAS User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 = Windows 8 64bit)

Hi Valine82,
Sorry you are having problems. You are using a 64 bit Windows system please confirm ?

  • How much RAM is installed ?

Your crash reports indicate you are using 90-95% of your available memory. But Firefox on Windows is a 32 bit system and that limits you to 4GB of useable memory. The crash reports & related bugs suggest it may be video related.

May I suggest these separate individual trouble shooting steps be tried

  1. Try in safemode and with plugins including FlashPlayer disabled. Can you confirm (or comment otherwise & include Crash IDs) that you do not then get crashes ?
  2. Try running normally but just with Hardware Acceleration (HA) disabled.
  3. Try updating your graphics driver and also if it was updated recently temporarily rolling that back.
  • Additionally you may be interested in about:memory for testing and reducing memory load. I will mention that further in my next post, and once I have seen your reply.

Hi John, thanks a lot for your answer. I have a 64 bit system indeed and I have 4GB RAM installed.

I am running Firefox in safe mode now and that seems to work fine.

I already disabled hardware excelleration before, but that did not make any difference. FF kept crashing after that.

Yesterday I noticed that the crashing occured when I used Google maps and the Spotify web player. But, sometimes it happended also on other websites. Those two were good for guaranteed crashing though.

Is it normal that FF uses 95% of the (4GB) RAM?

Hello, It shouldent be using that much system resources and if it works fine in safe mode then you might want to try uninstalling firefox then reinstalling fresh.


Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!

Thank you.

The problem posted here might be caused by a bug which is identified by your crash ID.

Bug Details:

Name: BUG 764342
Details: [https://bugzilla.mozilla.org/show_bug.cgi?id=764342]
Bug error time: 27 secs before submission.

Malware details:

Numbers: 0 Source: By checking your first crash ID

SECOND CRASH ID REPORT
BUG 745676 found

THIRD CRASH ID REPORT
BUG 805406 found

Mozilla has identified these bugs and is working on it through Bugzilla. In the mean time, I would recommend to first Uninstall Firefox completely. Then, restart your system and perform a malware scan (Avast! Free Antivirus might come handy). Then download a fresh version of Mozilla Firefox from here here and Install it.

Glad it works again. Thanks for posting back.

"Is it normal that FF uses 95% of the (4GB) RAM? " 
No that is unusual. Probably seen most often in crash reports .

Curiosity, I note the third Report appears to be from a Nightly version of Firefox crashing less than 1/2hr after it was first installed, presumably you have multiple Firefox versions installed.

I am not certain the reinstall was necessary in the end, but you fixed the problem anyhow.

Bugs, and my personal comments

  1. Bug 764342 first showed in Firfox13 to 16.It is marked,as a regression, but no one has commented on it in months and it is not assigned to anyone.
    Bug 818839 - OOM crash when scrolling a website with heavy images That seems to have resolved itself and apparently not a problem by Fx23
  2. Bug 745676 - Canvas crash [@ mozilla::gfx::AlphaBoxBlur::AlphaBoxBlur] again classedasaregression,unassignedand last commentedonin Fx12 days.
  3. Bug 805406 - crash in gfxContext::PushClipsToDT with Direct2D 1.1 (d3d11.dll 6.2 or 6.3) First seen in about Fx18, unasigned, but still receiving attention. (I understand it to be mainly seen on certain graphics cards and NOT in safemode)
