Firefox Community Forum

i have uninstalled, reinstalled many times. I cannot load the program once it has been uploaded to my laptop. always get error that it cannot find the URL. ICON shows up on desktop but clicking on it just brings up that error.

Firefox launch opens /home/pdl/Documents/Browsers/Firefox/chrome as a new tab, I have set the setting "Open previous windows and tabs" on and off, I prefer this setting to be enabled, my OS is LMDE 6 and Firefox is the flatpak install version 137.0.2 (64-bit), I have also tried the system install and deleted all Firefox in between installs or should I say I think I did, please this is driving me nuts, even with me logged out of Sync this happens.

Thanks

So anytime about a month ago, everytime I boot up my PC then first thing I do is double click on Firefox to open it and that worked fine until a month ago, now when I do it youll see the circle spin for 1 second and spot but Firefox doent open, no matter how many times I click on it, the only way Ive gotten it to work is that I have to restart my pc and try again until it eventually DOES open when I click on it, I usually have to restart 3-5 times before itll open.

Im wondering why that is and how to fix it? I havent done anything new to my PC since then, no new Firefox addons, also if there was a problem with Firefox itself then restarting should never make it open yet it eventually works after a few restarts. soooo i cant be Firefox right? Ive also tried refreshing firefox as well as going to add and remove programs and uninstalled it then reinstalled it the issue still remains, any way to fix this?

Ever since the latest update, whenever I right click the Firefox icon in the pinned tiles on the Windows Start Menu, the options to launch a new tab, new window and a new private window don't show up. They show up when I pin Firefox to the taskbar but not the Start Menu.

Images attached for illustration: right-clicking Firefox in Start Menu and right-clicking Firefox in taskbar

I am trying to sign in , Firefox is my browser. message come on that firefox is running but it does not open. I close it once and again as the same sign comes uo telling me it is running and close the attempts.

Do I really NEED to swithc to another browser to avoid this?

Hello, today I could not launch Firefox on my Mac. Because this is a corporate machine from Kyndryl, I downloaded from Kyndryl App Store, I have rebooted the systems, I have updated iOS to last version, but still haven't solved the issue. This is the situation: Firefox is installed, I click to launch it, I am asked to authenticate with MFA I authenticate correctly, and Firefox just sits at the dock bar jumping, then stops jumping, and nothing else happens. I repeated the process several times, made several reboots, nothing changed. Can you suggest a solution?

We use firefox for accessing several websites for our town. We are getting an error message : "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have tried closing the open window and I restarted the computer several times, with the same result on the message. I am running Windows 11.

When I first open Firefox from the icon in my taskbar the opening window says the following:

'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'

However this is only the first window, after that I can open a new tab in the same window without any problems.

I have uninstalled and reinstalled Firefox without avail. Can anyone help please?

After Firefox updated today, the executable no longer starts. I get the following error message:

firefox.exe -- Bad Image

C:\Program Files\<Mozilla Firefox\gkcodecs.dll is either not designed to run on Windows or it contains an error. Error status 0x000000d. </p>

And then another error message: Couldn't load XPCOM.

Please advise.

I am quite certain there is a connection between Firefox (latest version 137.0) and the Brother Print and Scan OEM software for model MFC-J6940DW for windows 11. After repeated attempts to re-install Firefox and restart the PC, Firefox still failed to launch. Only after deleting the Brother app will Firefox now reliablly start up every time. Curiously, the same phenomenon occurred on my 2016 Lenovo Yoga X1 running windows 10.

I hope a diagnosis can be made, because I found the Print and Scan app nice to use.

It's just my $0.02.

I’m on Windows (latest updates) and using the most recent version of Firefox. Whenever I try to play YouTube videos, they either buffer indefinitely or won’t load at all. I’ve already tried:

   Clearing cache and cookies

   Disabling all add-ons and extensions

   Toggling hardware acceleration

   Creating a new Firefox profile

   Uninstalling and reinstalling Firefox from scratch

   Checking DRM settings (Widevine)

   Updating my graphics drivers

   Temporarily disabling antivirus/firewall

   Flushing DNS and trying a different DNS

None of these steps solved the problem. YouTube works fine in other browsers on the same system. I’d appreciate any suggestions or help to fix this. Thank you!

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,
