Hi!

I don't understand. Firefox is eating up memory again in the latest versions, and on top of that, it's the GPU on my PC.

4GB for the app and up to 8GB.

Are you mining Bitcoin on my machine?

What are you doing?

So ever since the desktop browser got updated i have been experiencing critical crashes and lag where my pc screen freezes and then goes to black until i restart my graphics card and quit firefox in addition to tabs crashing and very weird performance issues overall, any fixes for this issue?

AMD ReLive instant replay does not work if mozilla firefox is open in the background while playing a game. It works fine with Google Chrome running in the background, closing firefox "fixes" the issue.

I have a question (speculation) about having several Firefox based browsers installed on my Windows 64 PC.

I have a Windows 10, 64 Bit PC with 64 Gigs of RAM. I've always had a habit of installing several versions of Firefox based browsers - all to no avail. However, as of recent, I'm finding that my browsers begin to slow down substantially after 15 minutes or so of browsing - please read on.

Right now, I have the following 64 Bit Firefox based browsers installed on my PC - they are:

Firefox Waterfox Floorp Librewolf

I have quite a large amount of bookmarks saved, and I make sure all browsers have the same bookmarks.

I have a half dozen or so of add-ons, and have tried - from time to time - to uninstall various add-ons to see if they were the cause of the slow downs, but none of that made a difference.

For example, let's say I'm browsing for 15-30 minutes or so, and have a half dozen different tabs brought up. After awhile, things begin to slow down substantially such as delays in clicking on links and having it respond, or right clicking, etc. Browsing speeds slow down substantially also.

Here is what I then usually do:

1. Create a new tab and type in "about:memory" and click on the save memory command.

2. Go into settings and delete cache.

This normally does nothing to speed up things, and I find I have to just close out the browser, wait a few seconds, and bring it back up to things to get back to normal.

This has me speculating - "Could" it be that having a variety of Firefox based browsers with similar data conflict with each other in some strange sort of way" Or is it something else? I know that having a bunch of tabs up can deplete memory usage, but as I mentioned above, I have 64 Gigs of RAM and never had this issue before.

My SSD drive has 500 Gigs of storage, and only half is being used.

Any suggestions or recommendations would be truly appreciated.

I keep getting the attached message when I sign into my bank. This just started yesterday (9/4/24), but when I sign in with another browser I don't have a problem?

We have an asp.net Blazor SPA (server side Blazor) that dynamically generates components within the page. Over time, there is a very large RAM leak under document-shared that climbs until the windows are closed.

We have tried various firefox configurations to try and either disable this shared storage as well as limit but with no luck. THe memory allocation is in GB of RAM space and cannot be limited or reduced until the window itself is closed/restarted.

Research online indicates this can happen due to colocated stylesheets and how firefox wants to cache styles aggressively. Adjustments to move stylesheets does not appear to help.

What configurations can I use to help prevent/reduce this high RAM usage? This does not occur in Chrome or Edge, I cannot replicate this well under FireFox for Windows.

When using firefox, and only when using firefox, I experience quite a lot of lag when using "google docs" (https://docs.google.com) and only when using "google docs", eg. this does not apply to, say, MS Word or google presentations.

Like I said this only applies to firefox, meaning google chrome and microsoft edge both work fine.

Here are some of the troubleshooting steps I've tried, without success:

  Launching in troubleshooting mode

  Disabling 0-RTT

  Disabling hardware acceleration

These issues do not appear on my machine at home, which also uses firefox, that however is a different version of Windows, an AMD cpu and a dedicated GPU instead of integrated, so idk if that narrows it down even one bit...

The computer on which the issues appear on is a HP Spectre x360 14, which if you don't want to search it up means I have 32gb of RAM @ ~7500MT/s, and an Intel Core Ultra 7 155H as my CPU.

I'd love to keep using firefox without having to fire up chrome every time i need to write/edit a document, which, as a student, is quite often...

Thanks a lot!

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...

He said its down to some update which for some reason I dont have but in the attached image, he is able to add his own wallpaper in nightly but I am not for some reason. Would love some support

Firefox is using about 15-20% of my CPU, with only one tab open. Running Firefox 141.0.3 (64-bit). I changed performance settings as suggested in support page; made no apparent difference. Ran Malwarebytes and McAfee scans; nothing detected. I have used Firefox for nearly 20 years, but if I cannot resolve this then I will drop Firefox and switch to another browser.

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

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?

Today Firefox crashed twice and a Tab crashed once! What's going on with Firefox? It's especially disurbing to have it crash during a long video and then you have to find where you left off.

I am running Firefox in Windows 7 on a PC. When I start up Firefox, in WINDOWS Task Manager there appear between 20 and 30 instances of firefox.exe of different sizes in the Processes Window. I can End Process on most of them without shutting down Firefox or any of the other instances of firefox.exe. However if I shut down one listed with about 200,000K of Memory (Private Working Set), then Firefox shuts down and all other instances of Firefox disappear. If I open an new tab in Firefox, more instances of firefox.exe appear.

I have never seen this behavior before. I tried uninstalling and reinstalling Firefox, but the same behavior occurred. Is this normal behavior, or should I be concerned?

I have enclosed screen shots from the Task Manager. I also have a Dump File of a couple of the firefox.exe instances, including the large one, if that would be helpful.

Thank you.

Dear Mozilla.

Yes, I'm using the dreaded Windows 10, I do understand it's at end-of-use, however this prob's been happening for ages. It's just got a little worse lately! (I've also got another hard drive with Windows 7 on it I swap the Windows 10 drive for sometimes. And we don't talk about the Windows XP hard drive with my music software on it. AARRRGGGHHH!!!! But the everyday drive with this problem is definitely Windows )

I don't use masses of extensions, just a VPN (which is there but not used a lot!) and is Proxy VeePN (that's its name, blame the designers, not me!) When I'm NOT using Firefox for a few moments, I hear the fans speed up, the hard drive spins like it's about to take off (old computer here!) The moment I touch the mouse, the fans all slump back to normal and the red 'HIGH USAGE' mark against Firefox vanishes back down to 'LOW'. Which makes it annoyingly difficult to analyze what's happening cos the moment I touch the mouse to find out what's happening, it stops happening!

Despite the above and its memory addiction - left to itself it munches memory like me with a crate of chocolate bars! - I do love Firefox best of all the browsers. I kinda know what causes the memory problem, by the way. I don't know all the techie terms but here's what's going on. Imagine you've got a house with an untidy kid in it. Every time one room gets too messy to use, you move into the next room. Eventually you run out of rooms. Then you restart the house back from day one, all the rooms are tidy again and you can use them all individually and happily - until Untidy Kid turns back up!

I'm on Firefox 148.0.2. If you've got any ideas about the CPU usage, I'm [email removed]@hotmail.com. It doesn't seem to matter what websites I've got in the browser, it just does this when I've got it parked in the background, it's like it's twiddling virtual thumbs through boredom cos it's not being used.

Yours respectfully,

Chris.
