Firefox Community Forum

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?

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?

Starting yesterday, browsing to the ebay.com url resulted in Korean language text being displayed per the attached screenshot. The same continues today. I tried the ebay options of changing language by choosing a national flag. Choosing the US Stars and Stripes made no difference; I still got Korean text. I tried disabling my VPN; it made no difference. I tried choosing the Canadian Maple Leaf flag and got English text but Canadian prices.

I tried to report the problem (in Firefox) using ebay's contact links; but those links require logging in. I could not because I could not pass the Capcha challenge while remaining in Firefox.

Thinking that the problem might lie with Firefox, I loaded and used the Brave browser. Not only did I get US English and prices straightaway, I was able to login with ebay and report the problem. My VPN is active and has been since I loaded Brave.

Because I have these problems only while using Firefox, I came here to report the problem and ask for assistance resolving it.

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.

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.

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?

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

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.
