I keep getting the 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 to close it using Task Manager as recommended in the help article, with no success. I have uninstalled it and even run the refresh instead of removing it, but still nothing. This is the second computer I am receiving this error message on, so any suggestions? FT

This started about a year ago. Whenever I click on an MSN article, the screen jumps about half a screen away and I need to scroll to get back to the headline and click again. This does not happen on any other website. It does not happen when I use MS Edge browser.

Hello, my Firefox was able to use the camera normally but recently I can't turn it on at all, it says it needs Windows permission but it seems on that front everything should be correct. Pics attached.

Just used sync in the past month with no issues.

Logged into sync today, immediately after logging in, the error message "Session Expired -- Sorry something went wrong. Please sign out from the browser window and try again." See attachment to see exact error message.

This exact error message appeared on both my PC's when I tried to sync between them. Any thoughts on what is taking place or is there a know issue with Sync from Mozilla today?

I have Firefox on Windows desktop and on my android phone. I have logged into both. When I click on "tabs from other devices" I only see tabs from another PC I use.

I tried logging out of Firefox Android and using the desktop browser's "connect another device" link to log back into it, but it still doesn't appear as a device. What am I missing?

EDIT: Ok now Android tabs are showing up, but not all of them. Seems to cut off after about 40. Anyway to get Firefox Desktop to show all Android tabs?

kein login in mein O2 E-Mail-Postfach (webmail.O2mail.de/#/login) mit Firefox möglich. Fehlermeldung: E-Mail-Adresse/Passwort falsch. Mit anderem Browser ist login möglich.

Firefox User here since Netscape Navigator. Problem occurred with latest Firefox release as far as I can tell. This rig works flawlessly with everything but Firefox and Thunderbird Chrome and Edge have no problems. All my apps operate normally. Almost all aspects of the browser/ display window are corrupt. Chrome and Edge and all apps function without issue. Included are two screen shots In attempts to resolve this issue I have uninstalled the video driver several times, including the use of DDU. I have done a deep uninstall of Firefox, including cleaning the registry and all hidden files. I have tried the latest video driver and several earlier versions; all exhibit the same issue. I can't use Firefox and its driving me nuts. I'd like to understand why Thank you for any advice and hints in advance

I have used Firefox for years, and especially since the ability to pin tabs was created. After this last update I experienced an issue on one website, which the tab is pinned, that was not present before. After putting things into my shopping cart, I click on the shopping cart and if the original tab is pinned then the shopping cart opens in a new tab. Before this latest update Firefox was smarter than that.

the new update is causing havoc. it keeps crashing pages which in turn is crashing my computer. i will have to resort to using chrome until it is fixed because i can't do anything.

I downloaded Firefox about 2 weeks ago. I imported my passwords, bookmarks, etc. from Chrome, but nothing had shown up. (I did the troubleshoot reset to fix the bookmark issue.) So I just figured I'd save them as I go. Every time I'm prompted to save my password, I do, but it's never actually saved. When I tried to manually enter the password, it says there's an error. I've checked the settings multiple times and everything is correct. I receive a little message at the top of the passwords' page, that says I need to log in, when I am, then that I need to log in with my primary password that was never set up. I've read all of the password help articles and nothing applies to my issues. I don't have any apps blocking it. (I do know on Edge and Chrome, I'm prompted to put in my desktop password but I don't get that on Firefox.) Is there something I can do to fix this? I want to use Firefox, but it's been too buggy from the get-go.
