Firefox Community Forum

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.

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.

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!

Desde que he instalado Macos Sequoia 15.4.1, Firefox no consigue abrir ninguna ventana de internet. Internet funciona porque con Google Chrome o Safari sí que puedo navegar.

Was in the midst of a Quickbooks data download and Firefox browser disappeared and Windows no longer lists it in programs save for "Firefox Private Browsing" which triggers an "cannot find" error message when I try launching.

Long time user and never had trouble.

There were a few error messages from anti-virus software during the transaction - which I assumed were due to interfacing with someone online doing the data transfer so I ignored them. So it could be related to that.

Firefox was my default browser, on two places on my desktop, now it is gone.

During the QB download process, I had to switch browsers and use Chrome to find my email etc.

I am fine with just uploading Firefox again, though I assume it means I will lose my open tabs and possibly any memorized passwords etc.

Please advise - Thanks

Guten Tag wertes Support

Seit gestern kann ich den Browser auf einem Laptop gar nicht mehr starten. Die Hilfe über den shift & Firefox-Icon geht nicht - somit kann ich auch die Proxisinfos da nicht ändern -. Auf einem anderen kann ich es schon. Doch alle gespeicherten Informationen zB. Passwörter bleiben mir auf dem anderen gesperrt.

Wie kann ich den Browser auf dem ersten starten - oder Passwörter wieder haben -? Danke

Freundliche Grüsse Chr. Lachmann

Somehow the file ended up on my desktop. I think I saw it in a wierd place so I moved it out hoping it would go where it was supposed to go but it ended up on my desktop and now Firefox won't open correctly. Help?

Have tried suggestions from other strings. Will not open in any mode on my Mac mini so cannot even uninstall. Continue to get message that It is trying to install a new helper tool but will not install or open. Restart did not work, shut down and restart did not work, “safe mode” with shift key or option key does not work.
