How To Measure Memory Usage Per Extension?

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

Often I open a new tab & it's bugged. (It displays fine but the "right click" menu doesn't work.)

The fix is right clicking the tab itself (at the very top) & then clicking "reload tab".

Is there a hotkey for this instead? I hoped ^{f5} would work (control f5) but it didn't seem to.

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

Hi. I am running a 3 monitor setup and I like to keep open quite a few tabs. And two windows of Firefox. So two Firefox instances with several tabs on each. But because it eats a lot of memory, I have to close and reopen Firefox from time to time. And to my annoyance, sometimes it "forgets" about one of the windows. So opens only one instead of both. Therefore I loose some quite important tabs. Any suggestions on how to fix this? Thank you.

I am using Firefox 122.0.1, Windows 11 with all latest updates. Recently my HP Laptop has been slow to respond. I rebooted and opened task manager. I started Firefox and it was using about 1500 MB of memory. I closed some tabs to try to recover some memory. However, Firefox kept taking more, more and more. After 15 minutes, it was at 10,000 MB and climbing, and my system was using 99% of memory. I don't believe Firefox did this in the past and this is clearly not working properly. Any ideas?

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.

I've recently installed "OneTab" extension and right after this my firefox stopped rendering (meaning it shows in the doc as if it is running, but there is no application that can be found on the screen)

I've read articles about problems with extensions so I deleted the whole firefox folder in the "username/library/application support" as I couldn't find anything connected to the onetab extension.

I've also reinstalled firefox both from brew and by downloading from the official site of mozilla. Of course, I've restarted the system a couple of times.

Help will be appreciated. Thanks in advance.

My system is macOS Sonoma 14.2.1

Hi. When Windows 11 was initially released, certain substantial feature of the Windows taskbar known from before was missing. I'm talking about 'Combine taskbar buttons and hide labels' and the option to set it to 'Never' (users tend to set it this way to always see the program icon along with it's label, not just the icon). At this moment, the feature has been available in widely released build of Windows 11 for months (Microsoft returned it after rewriting the taskbar code and after many complains), but it is not working correctly in conjunction with Firefox. When I close all windows and tabs of Firefox and restart the browser, only its icon is visible on the taskbar, not the label. Only when I open one more Firefox window, it starts to work as it should. Is it a known issue? Can we expect a fix to be made soon? Thanks.

I am using Firefox in a Linux environment with multiple workstations, where I may be logged into more than one workstation at once. The workstations have an auto-mounted home file system such that my home directory (including my Firefox profile directory) are shared.

Because of this, when I try to launch Firefox on a second workstation, I get an error saying "Firefox is already running but is not responding". I have read the support articles about this issue, and other community support threads, but none of them address this use case.

I wish to use the same profile, so that I still have all my bookmarks and such, and have them continue to stay up-to-date. How can I do so in this environment?

I asked this question about 115.4.1 and was told to try in safe mode. However I cannot connect to my mail servers of which I have 2 and Gmail when in safe mode. Please look into the resource handling problem with the new Thunderbird under Win10.

1) Whenever I open Thunderbird the Gmail messages apparently get refreshed taking several minutes. I have cleaned up that inbox and limited to 366 days of mail.

2) I spent hours moving mail from past year from my other accounts into local storage. You no longer can scroll and block select more than about 20-30 messages at a time regardless of the background activity 1) above. The program requires you to repeatedly release shift key to grab more than a few messages. If you are able to grab say 1000 messages, and try to move them, the system chokes and does not respond.

3) Any background activity impedes the ability to scroll the inbox.

The new versions are crippled in some way as far as resources. The older version was more tolerant.

Please listen to complaints. Putting in safe mode I cannot troubleshoot. It is also very difficult in Win10 to follow instructions to safe mode unlike previous OS.
