When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

Just got a new laptop with Windows 11, installed Firefox, and am running FF 98.0.1. When scrolling on some pages, the buttons look like they're constantly flashing. But if I scroll slowly, I can see that the button color is itself scrolling within the button boundary. Or at least, that's what it looks like. Attached a sequence of images to show what I mean. Can anyone help? It's so irritating that I might be forced to use a different browser, which I don't want to do! This didn't happen on my old laptop running Window 10.

This is the third time I've lost all my passwords (and logins) since the beginning of the year. I had over 200 when I lost it the first time. I've entered over 75 since then and today I just lost those. Fortunately, I had a backup of my profile. The old "key4.db" and "logins.json" files I had didn't work, although they have a significant size. In fact, looking at the "logins.json" using VS Code I see the logins are there but they don't display in the "Settings > Privacy & Security". How can I get access to them when this happens again. I was able to restore the profile from several days ago so I'm not completely in trouble.  :-)

I've always used Firefox browser instead of Microsoft Edge, and I would like to continue using Firefox. However, it will not run in its current form under Windows 11. Does Mozilla plan to keep it compatible with Windows? I would like to keep using Firefox.

I don't need any images, you know the problems ... Freezes, no internet access.

Hi......,

I have had firefox browser for a while now and it has always worked fine. Now I`m suffering from that internet pages can`t be loaded ( see attachment ). I think,am not sure since the last update. The weird thing is that youtube does work and can just play video`s also 4K. I have read the error report but can`t really do much with it. Is there anyone who can help me in the right direction?

Thanks in advance for the trouble.

Hi,

Almost daily, I have to delete cert9.db and restart Firefox, otherwise I can't access some websites, or even web interfaces of local devices on our LAN.

security.enterprise_roots.enabled is greyed out, so I can't change that but it is set to "true", which I believe means that it should be using Windows Cert store and not cert9.db. Yet still, deleting cert9.db is the solution to my issues.

Can anyone advise on what I can do for a more permanent fix?

Thanks,

M

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Firefox: 97.0 (64-bit)

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

A while ago I formatted my computer, and installed FireFox for the first time. Ever since installing FireFox, I noticed an issue which has been a constant source of frustration, when I rewind any YouTube video the playback volume changes to a lower value, until I rewind again.

I tried looking online, this is the closest match I've found, but there's no solution there

I tested this issue on different browsers (Edge, and IE), no problems there. I tried disabling extensions, no change. I tried resetting FireFox, no change. I made sure that Windows doesn't automatically adjust system volume. I tested this issue on different Video platforms, no problems there.

I use YouTube when I practice (music), so I rewind a lot.

Any help is very appreciated.
