Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

Hi, I've been using Firefox on all my devices for YEARS without any issues. However, as of recently, I had moved into a new apartment, and with that came a new internet connection, which was very slow since the beginning, but usable.

At first I had assumed that Firefox on my PC was loading websites more slowly because of my poor internet, which was partly the case - however, my laptop and Android phone were on the same network as the PC and were both much faster. So I assumed it had something to do with the differences between WiFi and Ethernet connections - the PC was plugged into the latter while the laptop and phone were using WiFi.

But then I noticed that Firefox was the only program with lacking speeds. Spotify loads video podcasts with no problem, Steam downloads are relatively fast (as much as my network allows), only Firefox took MINUTES to load a simple web site. For example, I tried opening Reddit on my PC to write this post, gave up, and am now writing it on my phone. The Reddit website is still loading on my PC as we speak.

I honestly don't know what could be causing this issue. I checked Task Manager, and Firefox isn't using any more resources than it normally would. I am also using the latest version, I just checked.

Any ideas or fixes? Even diagnosing the problem would go a long way.

On my windows 10 desktop firefox will not work, message ‘Couldn’t load XPCOM’ . How can I get it fixed as I no longer have internet access

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section.

pls help me here

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

Stuck with this hourglass logo on tabs since the latest update v121.0

Now what I have noted is that this is causing the pages to load slow. Only ublock extension is installed, tried all dns settings but the result is the same. Is anyone facing the same?

These pages say to change the value and this hourglass thing will be removed

But I cannot see any option to change the value on that location

What to do now?

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!

It seems like more often lately that in the past. I just tried to post on the Portableapps website, and had all sorts of problems there.

I had to use Chrome to post. Actually, when I went first opened the page in Chrome, I got an alert that six trackers were found, and did i want to disable them.

Perhaps that relates to Firefox and accounts for some of the bad behavior?

I'm getting tired of this. There must be a happy medium between security and unencumbered usage.

Maybe it's one of my apps, i.e. Canvasblocker. It has a ton of settings options, and I don't have a clue what to do with them. Aside from that and Ublock, I don't see any others that fit that category.

Maybe it's something in my browser settings?

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

Hello!

I use Mosaic, a window manager utility, for macOS. With a hotkey, I can move or resize a window according to a preconfigured grid.

This always has worked great with all different applications, and only in the past couple of months it stopped working with Firefox.

It appears to be related to the way Firefox is does animation of resizing or window movement. My hotkeys no longer have the effect on the Firefox window moving.

This is disruptive enough to my workflow that I have switched to Chrome, which doesn't have the same issue. I really am not okay with this solution, as Chrome is the worst for a software developer. Tab and session management in Firefox is the absolute best and I want to come back to FF.

Is there any way to completely disable whatever window animation features have recently been added to Firefox?

Firefox app on Samsung Galaxy s22 ultra keeps flickering, this occurs 2 out of 5 times when app opened, tried to reinstall app, delete cache, force stop app..but it keeps happening, this seemed to occur after last app update, once the app is force closed and reopened then it responsds normally but once closed and reopened the error is back.

I'm trying to install & use Firefox as my browser of choice on this new computer. Using the migration assistant, Firefox seemed to transfer to the new computer with no problem, except that it did not work. Neither does, apparently a new installation directly on the Mac Mini. Any suggestions? I do prefer to remain with the new operating system if possible

Thanks,

When I sign in on my Microsoft Account FF Password Manager Does nothing. I open up the passwords but the manager does nothing. How do I correct this? It is as if FF does not recognize I am being prompt for login info. This only happens with this cite. Thank You for your time Mike

When I clicked troubleshooting mode FF unexpectedly closed my Private browsing session and all the tabs. How do I reopen them?

I did not expect FF to close on me like that. I thought that as I was in a private browsing session FF would have warned me that it was about to close had it been necessary.

I'm guessing that my open tabs have been lost permanently because you didn't warn me and that all that time I spent is now wasted.

Life is really simple except that other people make it problematic.
