Dear Community,

Using Cloud applications via browser and my mail webbased I have Firefox installed. This browser was in my opinion always the better choice, but last months I experience strange behavior, cache issues, freezing pages, crashing tabs which is very annoying and frustrating when working in the cloud. In the same session it is possible that I suddenly can't open objects anymore or click on URL's, buttons not reacting or even can't login again, even when I just was logged in successfully. After refreshing and restarting the browser or sometimes even after restarting my device, everything is working properly again for a while. The same issues I have when using the incognito browser, especially when I use this for cloud application for example. I can't explain and my questions are: - anyone experiencing, familiar with and or know of this same kind of browser behavior and - if yes, how to solve this?

Thanks in advance and kind regards,

Aad

When Firefox ver. 143.0.4 (64bit) is opened, I see many tiny groups of black dots withing the whole of the desktop display of this Firefox. From these black dots I see coloured lines traveling across the desktop within the Firefox desktop display. As I move the mouse these coloured lined move, disappear, and move around. Can you offer any suggestions. I am using Ubuntu UALinux Gamepack 22.04, The version of Firefox is an upgrade provided by Firefox updates. I have tried to uninstall this version of Firefox, same effect occuring. I have manually deleted every referance to Firefox, as this worked in UALinux Gamepack 20.04. I have used sudo apt update, sudo apt upgrade, sudo apt --fix-broken install, and sudo dpkg --configure -a. None of these can fix this problem. I restarted my Firefox today with the same problem, and found in the Help dropdown menu, and found troubleshoot mode. When I opened in troubleshoot mode, all these problems are not there any more.

Can you offer any help ??????

P.S. I tryed to take a screenshot of this problem, but the screenshot doesn't show this problem ?

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.

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?

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...

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!

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

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 :)

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.

For the past few weeks, my PC reliably crashed after a few chess games on chess.com with Firefox. GPU and Memory benchmarks are running through without issues, it did crash when starting a Steam game once before, but I wasn't able to find out why. At this point, I'm really curious to learn about what could possibly cause this, but don't really know where to look for it. Really wondering what special thing is happening after a game there that doesn't happen with other websites/browsers. Would really appreciate your help!

Running Wayland on Archlinux 6.15.7 with AM5 CPU and DDR5 memory. Sometimes wondering if it's a graphics issue since my display is connected via the iGPU, but I also have an NVIDIA graphics card installed that I use for games sometimes.

Hi: There is no Refresh Firefox tab. I go to Help More troubleshooting information. Like I've done a million times. And for Diagnose Issues there's only a Troubleshoot Mode and a Clear startup cache tab. No Refresh Firefox tab. I did not want a new profile. I did not want additional profiles. This has messed everything up. Firefox is not working. Thank you
