Firefox Memory leak.

Skrevet

Hello,

Both Firefox dev and standard are having a problem where if i leave my browser open for some time the CPU usage goes up and it will use all 32GB of my memory until it crashes my PC, this is a content thing.

I have tried clean uninstalling both and it has fixed nothing it has gotten so bad that i need to restart firefox every 30 minutes or so I might need to swap over to an other browser at this point.

thanks for any help i can get,

Hello,

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • Click the menu button New Fx Menu , click Help Help-29 and select Restart with Add-ons Disabled.

When the Firefox Safe Mode window appears, select "Start in Safe Mode".

SafeMode-Fx35

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

You can check the Firefox Task Manager page (about:performance) and about:memory page to see what is going on.

Is there a way for me to create a log of some sort once the memory hit's around 10GB+ ? is there no way for me to debug this ?

You can try on the about:memory page. But it can be difficult, I'm not very familiar with those measurements.

Ok i found something strange, I waited for it to happen again when i noticed it starting it went from 2GB to 5GB in 20 seconds and was going up fast, it hit around 5GB memory i went to about:memory and clicked minimize memory, now this is where the strange thing happens firefox split a processes off that was still 5GB+ going on 6GB and climbing but the main firefox process went back to normal memory usage, so i ended that split off processes and firefox didn't close everything was as is with out needing to restart firefox.

EDIT: Something interesting im not sure if this is related but youtube tab i had opened had crashed after i ended that process. could be related ? going to use youtube in a separate browser and see if it happens.

Try to disable webrender and set this pref to true on the about:config page.

  • gfx.webrender.force-disabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

So far so good, disabling webrender has decreased my memory usage by more then 50% and when i quit out of tabs now i see an instant drop in memory, ill post again after more testing to see if the memory leek happens again.

overall with webrender disabled i feel like the memory management has become a whole lot better.

Is this a problem with webrender ?

It looks like, but I can't see it here. And I'm not experiencing it on my computers (I'm on 69).
