Huge memory leak from FF is causing my computer to shut down

Hello all,

I have been experiencing a critical issue with FF for more than a year now and even though I reported it via the FF crash reporter numerous times it never got fixed so I figured I would report it here.

The issue could be summarized as follow: browsing the website mixcloud.com triggers a memory leak from FF that eventually causes my whole computer to shut down if FF cannot be "force[d] to quit" in time.

Here is a more detailed description I sent to Mixcloud support last year:

"Often times when I open a new page/tab on the website the loading freezes and after a few seconds a yellow warning notification pops up on the upper part of the screen asking: "a web page is slowing down your browser. What would like to do?” with the two following options available: "Stop it" or "Wait". If I click "stop it" the loading will indeed stop and I just have to refresh the page again to continue browsing normally. The troubles begin if I click "wait" or do nothing: the overall memory usage of Firefox will then increase seemingly exponentially and after only a few minutes the whole system will become unresponsive and I will have to hard reboot my computer or it will reboot by itself. This is extremely annoying as you can imagine as every time that happens I lose all unsaved data in the process! Strangely enough this issue sometimes even occur without any notification displayed or freeze happening in the first place: I would be browsing a few Mixcloud pages then switching to another website and after a couple of minutes I would notice that the memory usage is increasing although no Mixcloud page is open any longer... In both cases the only solution I found is to quit/force to quit Firefox as soon as possible to prevent it (and the system) to become unresponsive. Closing the application always resolves the issue and I can see the memory usage of the overall system subsequently dropping sometimes from up to 95% to 40% in the Activity Monitor app. Again I would like to stress that I have been experiencing this issue ONLY on Mixcloud and that I have no other memory related issue on my computer nor with Firefox in general."

Mixcloud support reply at the time: "this is linked to some issues we've been experiencing but our team are busy working on a fix for". 10 months later nothing changed...

The same issue happened again this very morning: I opened a Mixcloud link from google results and even though I immediately closed it, 5 minutes later the RAM usage was at 93% and I struggled during 10 minutes to "force to quit" FF as the whole computer was becoming increasingly unresponsive. I can provide a crash report from this morning but would prefer not to display it publicly.

Please investigate this leak. It is becoming more and more frustrating to deal with as the time goes by.

Firefox Developer v80 Mac OS failes to render new css even after cache flush and reload

I've been using Firefox Developer version for some time now on Mac OS and have never had a problem like this before.

However, since version 80, Firefox Developer fails to render the new css after a change and save has been made to the style sheet even after multiple browser refreshes. Caching on the server end has been disabled so I'm really trying to find a solution to this issue as it has forced me to find alternative browsers to develop with like Safari since Firefox Developer has become unusable for me.

I've gone through and performed manual cache flushes on the browser from the settings/preferences panel. On occasion, by quitting Firefox Developer edition and relaunching it will then render the new changes but only after a quit and relaunch and sometimes using a private window as well. This is happening with multiple hosting services so it's not any particular provider.

This is most annoying. I've even reset Firefox Developer a number of times to default settings without any extensions etc. and still the problem exists.

Earlier version of Firefox Developer don't seem to be exhibiting this problem. I'm not running any proxy's or special configurations with the settings either.

Any assistance to finding a workaround would be greatly appreciated or I'm going to have to stop using Firefox Developer version altogether.

Thank you,

Over the past 6 months or so, I've noticed that I occasionally get corrupt images where the images are replaced by semitransparent, randomly colored vertical lines, as seen in the provided screenshot. I am unable to reliably reproduce the issue, and it seems to happen somewhat randomly, but recently its started to occur more frequently.

I am on the latest version of Windows 10 Pro, and all of my drivers are up to date, to the best of my knowledge. I'm not entirely sure this is a Firefox-specific issue, and I seem to remember the same problem occurring in the default windows 10 photo viewing app, but I'm not certain about that, it might have just occurred when I opened my images for viewing in Firefox.

I appreciate any help or insight anyone can provide, thanks!

Last night, I noticed that the usual Dock icon for Firefox developer Edition had changed from Blue Fox to what looked like the App Store brush/pencil triangle. I restarted but it persisted. Removed the application and re-downloaded and re-installed, but same issue. I then noticed that all the Tools -> Web Developer tools had gone from the menu. Likewise, doing Firefox -> About inserted 'about:preferences' in the search bar, but nothing else happened. Tried launching the settings from the right side hamburger menu, again nothing happened.

Read around a bit, and deleted one of two profiles from ~/Library/ApplicationSupport/..., then tried re-install and restart the Developer Edition, but that complained that a profile was missing. Restored the profile I deleted, but same problem as before.

I'm stumped. Can anyone help with this one please? I'm on Mac, latest version of Mojave.

Thanks

Not a serious bug, but firefox warns about cancelling downloads when trying to switch profiles without actually exiting the browser. Please take a look at the attached image.

If I somehow click on "Cancel 1 Download", it does nothing, just launches the profile I am launching. So the warning actually means nothing, and should be removed.

Thanks.

Hi,

If I already use a password manager service, why would I be required to have something similar with Firefox, I don't understand, why would I even need a password with Firefox, is it for added security? I am using a few Firefox extensions, is it for that? Every time I sign on to Firefox browser, I'm prompted for a password. When I headed over to settings to cancel it, a message said not to. This feels more like a pain in the b**t?

Please advise Thanks for helping

I've got multiple clients set up to sync via FF sync. Some are older, some are newer.

However, looking at the newest client (set up ~2 weeks ago), I noticed something: It only shows a browser history up to approx. one year in the past. I've checked other clients. My oldes client goes back to ~2016, which is 4 years form now. I know my oldes client is older than 2016, so there has to be more.

Does FF Sync skip older entries? IMHO I'd have to see the exact same history on my older client than on my newer client. That is not the case. Any ideas?

But it doesn't remember, so I have to select Thunderbird from the list every time. Thunderbird is set as the default in the Options>Applications menu, but it still asks every time.

pressing Ctrl+F doesn't open the "find in this page" toolbar, on any page.

  • doesn't work in safemode, either
  • DOES work when selecting from the "Edit" menu (where it shows the shortcut as being ctrl+f)
  • I read online that Ctrl+G might work? this one has mixed results for me... I think it's working like F3, repeating the previous search, if there is one, and if it has any matches, and only if neither of those are true, opens the "find in this page" toolbar
  • pressing "/" and apostrophe both do their things (but not when an input/textarea has focus, of course)
