Firefox Community Forum

I use translation A LOT. (I'm learning a foreign language.) It would help to be able to move or resize the results window. Right now, it covers the original foreign language text. I want to compare the translation with the original text and the fixed size and position of your results window makes that a lot more difficult.

Lately every time I open Firefox on my PC (Win 10) it says that it is already running and that I need to close it first. How can that be if I just started the computer session?

For about one week (or more) results of my questions or other input have resulted in suggestions/sites in Spanish. Yes, I live in South America, but I do not speak or read Spanish. I have chosen English as my preferred language. What's up?

There is no Japanese in the language to which the website is translated. It is understandable that Chinese is available in the Asian region. However, we would like to ask why there is Indonesian, Vietnamese and Korean, but no Japanese.

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

The Firefox stable desktop taskbar shortcut issue unresolved for many months. Every time clicking on the Firefox taskbar/start shortcut is non responsive or it gives the error class not registered. Firefox nighly/developer do not have this issue. Fujitsu laptop, Widows 11 lates upgrades. Please fix.

Firefox will not update when I click the restart button. Firefox restarts but does not update. Closing Firefox manually (X) several times did not help. I had to restart my laptop and then Firefox updated. This started happening the update before 136.0.3, which is my current version. I don't want to keep restarting my laptop every time there is a Firefox update, which seems to be happening more frequently.

I can not open my firefox browser. I never had this problem before. When I click on the icon I have on my bottom of my computer it says I can not get on it says many different error messages being sent. I am not a computer whiz so what should I do? should I uninstall it and re-stall it? would I loose everything I have book marked. HELP

I have updated FF on four PCs to 136.0.3. On just one PC, FF launches to a small window which is completely non-functional. None of the visible controls do anything. I can't move the window but I can resize it but everything is greyed out except the search bar. I can type in the search bar but get no search.

I have read a number of similar posts, but these fixes do not work: I cannot toggle the full screen using F12, I cannot change the launch behavior by setting 'maximize' in the shortcut properties, Deleting xulstore.json (repeatedly) does not fix (I have no localstore.rdf), I have no access to any of the normal FF controls that would let me refresh or troubleshoot.

I could always reinstall, but thought I would ask first.

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.

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?

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?

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?

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.
