Firefox Community Forum

i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.

Of 3 macs in the house, all on OS12, the one on ethernet to the ISP has been failing regularly: 1.) fails to collect history 2.) fails to present long-time home page 3.) if it does boot-up properly, expected behavior slows down markedly during a session on the computer (Usually rebooting the entire machine restores this. This morning even that didn't work.)

FoxFire (v146.0) crash report is available. Here is infor on machine:

When my laptop is connect to a monitor via HDMI cable, the resolution on Firefox switches between what my laptop is at when not plugged in and the current monitor's resolution. It almost looks like Firefox is hiccuping between resolutions. This last for a few seconds and happens frequently within the hour. How can I stop Firefox from being confused about the resolution it's supposed to be at?

I have had a dual boot Windows 10/Ubuntu Linux set up for many years, with Firefox installations in the two operating systems both using the same profile accessible on a shared a disk partition. Since a Ubuntu update several months ago, using Firefox under Ubuntu produces the "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." problem when I revert to Windows and try to run Firefox under Windows. I can clear the problem by running a disk check in Windows on the shared partition, but does anyone know how to avoid this?

Frequently when I hibernate my laptop firefox prevents its (as soon as it enters sleep it wakes up)

when I close firefox it hibernates fine

when I go to powercfg /REQUESTS its the audio card that is driving the wake up

In settings I have turned media.video-wakelock. to FALSE etc and firefox still wakes the computer

Hi, Please help with my issue: There are 2 Firefox browsers running on my Windows 10 desktop. How can I find one to delete it. My CPU is running very high in Task Manager. Thanks, I just can't find it and I desperately need to do so before my computer crashes! Many thanks any help you can offer is very much appreciated :)

My computer, being 7 years old (and without the space to upgrade to WIN11), has always been a bit slow with low RAM and storage. The swap from Chrome to Firefox essentially gave it a second life, as Firefox didn't need a lot of space to run. Recently, though, it locks up with almost every search, refusing to let me x out a tab and try to save myself for 3 minutes or more, and the bluescreens have come back, too. If chrome hasn't also gotten worse, I'm considering switching back. Does anyone know what happened? I haven't installed anything new.

It's really frustrating and disappointing, because I thought I had a solution when I swapped to Firefox.

Hello everyone,

I have checked a lot of other questions already but I can't seem to find a solution to my problem.

I have Firefox installed on an old Laptop with macos Catalina. Reinstalled it many times with and without extensions, without any data but it doesn't matter what I do, even on a blank slate of a new reinstall of Firefox it just takes way too long to load or doesn't load at all and then even hangs up so that I always have to force quit it and slows down the entire laptop. It also sometimes loads tabs only if I reopen them or have to go to an already open tap that has been working to be able to open it.

I have been feeling super frustrated for days because I can not figure it out.

Thank you all for taking the time!

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

26200.6899 - Windows 11 pro OS version 144.0.2 (64-bit) - Firefox version

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.

Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

Hello. My tablet, has limited memory, due to its age. I am now finding that one of the main reasons why it is so slow is because whenever I open firefox, it opens multiple firefox processes which drain the memory and in some cases crashes the system. I have followed all the advice given to reduce these multiple processes, however nothing seems to work and at least 6-8 firefox processes open each time I open it. I have unchecked the recommended performance settings as well as hardware acceleration boxes. However, I cannot find where to set the content process limit to 1. Please tell me how to do this and if there anything else I can try to stop it opening multiple processes or I may be forced to ditch Firefox altogether for an alternate such as Bing, Chrome or DuckDuckGo. Many thanks. Charlie

Firefox stürzt seit einigen Wochen immer wieder ab.

Auch ist es sehr langsam, oder lädt die Seiten nicht.

Auch kann ich nichts schreiben, zwischendurch.

Es nervt!

Und ein neues Update gibt es nicht.

Wenn es so weiter läuft, muss ich einen anderen Browser nehmen, was ich gar nicht möchte, da ich Firefox, seit Anfang an benutze...

I have nothing but problems with firefox since the last new updates. Sites hang, gmail can't be accessed, it takes 100x longer for sites to load, firefox uses huge amounts of memory and CPU, etc, etc.

I am so fedup spending valued worktime having to solve firefox issues each time they decide to make updates - which seems to be more and more frequent. How can I roll back to a previous version and permanently disable any further updates?

Each time I click on Firefox from the Windows 11 Task Bar, multiple versions of Firefox appear in the task manager (see photo). Some have an icon next to them that says "efficiency mode".

The attached screenshot is what I got from loading Firefox to ask this question. Multiple scans of my computer using Norton 360 -- including the Startup Scan -- have found nothing awry.

The operating system is Windows 11 Pro Edition Version 24H2 (OS Build 26,100.6584.) Firefox says it is fully up to date.
