Firefox v18 keeps crashing every 20-30 seconds

I just re-booted my machine today following a Windows update. Since boot-up, my Firefox browser crashes about every 20 seconds.

I notice that I now have Firefox 18, and presume that the latest version became active after my re-boot.

Sometimes the carsh happens after I have opened a few tabs, sometimes when I am just entering some google search terms, and sometimes when I am doing nothing. It seems quite random but I cannot seem to use Firefox more than about a minute before it crashes again.

Sometimes, the crash automatically closes all Firefox windows, and I have to re-start.

But usually the crash, just causes Firefox to freeze. And I have to manually shutdown the Firefox process and restart it. On these occasions I have noticed that the memory used by the Firefox process continues to increase - I saw it increasing beyond 3Gb the last time. There seems to be a memory leak on these occasions. However, the extreme memory use/memory leak does not happen every time that Firefix crashes.

I just noticed that when Firefox crashed the CPU usage of the Firefox process, as reported in Windows Task Manager, is exactly 25%. I had this same issue with a much earlier version of Firefox (I think v6 or v7) continually crashing, when the CPU usage hit 25% - I reported that error at the time, and a new version was released shortly afterwards.

Re: Firefox v18 keeps crashing every 20-30 seconds

First thing you said caught my attention & is what I would try first. You said it started happening after you installed latest windows update which has nothing to do with updating FF btw..ff update element is seperate. I'd install the latest update in control panel, view installed updates & locate most recent & see if that helps

Re: Firefox v18 keeps crashing every 20-30 seconds

Thanks for your reply, but I don't fully understand your comments :-(

I've looked at what Windows updates took place recently (and hence required the Windows reboot today). They are all 'Security updates for Windows 7' or 'Security update for .NET Framework 3.5.1'

They are all required, so I don't believe I have any choice to install or not (and assume I should anyway, to maintain Windows Security).

I fully understand that the Windows update is NOT a FF update, although updating Windows components (eg. .NET Framework) 'may' have an impact on FF - although I assumed that Mozilla would have tested against such Windows updates.

I do not carefully monitor the version of Firefox I am currently running, and these days a new version comes out quite often. The last time I looked I was running FF v17, so I'm guessing that this got updated to v18 when I rebooted too. (Gone are the days when there was only one update every year or so.)

Re: Firefox v18 keeps crashing every 20-30 seconds

One more specific point. I think the fact that the CPU usage hits 25% for the Firefox is quite crucial!

My browser has crashed about another 7 or 8 times in the past 10 minutes. Each time I have noticed the CPU usage hit 25%. As I said in my original note - I noticed this behaviour in another earlier version of Firefox, which got rectified in a following release.

However, I don't know if hitting 25% CPU usage is the cause of the crash, or the crash is the cause of hitting 25% CPU usage.

Re: Firefox v18 keeps crashing every 20-30 seconds

I have the exact same problem as doninwales.

I am running Windows XP 64 bit.

Once I upgraded to Firefox 18 last night, now every 20-30 seconds, Firefox freezes, or crashes. Sometimes i have a few tabs open, sometimes only 1.

Many times it just freezes, and I check task manager to end process, and CPU usage for Firefox is exactly 25% every single time.

Unlike doninwales, I have not done any Windows update. My windows updates are turned off.

I have ran windows mmc service with event viewer plugin, and it reports application hang errors.

If you have submitted crash reports then please post the IDs of one or more crash reports that have this format:

  • bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the IDs of the submitted crash reports on the about:crashes page.

  • You can open the about:crashes page via the location bar, like you open a website.

Re: Firefox v18 keeps crashing every 20-30 seconds

If they were installed then you have a choice of uninstalling them, this goes for both required & optional updates and applies in most cases with exception being if they are system specific to the OS updates.

Here's the process to uninstall updates for Win 7.

The Windows Update log file is located at C:\Windows\WindowsUpdate.log.

You can uninstall each two different ways.

Option 1.

  • Open Control Panel & select windows update
  • Select view update history
  • Click on the Installed Updates link at the top of the View update history window.
  • Select a listed Windows Update that you want to uninstall, and click on the Uninstall toolbar button.
  • If prompted by UAC, then click on Yes or enter the administrator's password.

Option 2.

  • Open the Control Panel (All items view), and click on the Programs and Features icon.
  • In the left pane, click on the View installed updates link.
  • Select a listed Windows Update that you want to uninstall, and click on the Uninstall toolbar button.
  • If prompted by UAC, then click on Yes or enter the administrator's password.

  1. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
  2. In that text field, enter %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID into the reply window on the forums.

Re: Firefox v18 keeps crashing every 20-30 seconds

Dbellca82 - I DO appreciate your replies. I appreciate anyone who is willing to try an help me. This is SO frustrating that Firefox crashes several times a minute :-(

Regarding uninstalling the Windows updates, I appreciate that I 'could' but I questions whether I 'should'. They are all marked as 'Security Updates' so I assume I 'should' install and keep them.

Regarding the crash reports, I 'thought' I had already submitted them in my original post. (As mentioned I had a similar issue a few years ago, so knew the process of submitting the crash IDs.) I'm sure I entered the crash IDs in the 'Troubleshooting Section' of the original post, but I don't see that section shown any more.

Or.....since FF crashed about 6 times whilst I was creating that original post, then maybe it got deleted.....
