Firefox-Hilfeforum

I've been utilizing the security protocol app DUO for work purposes for the last year with Firefox, no issues. I just recently updated to 105.0.1 and received the following error message when my DUO was prompted:

• "We're sorry, access is not allowed with Firefox due to security concerns." - with a sad face.

It then shows me a list of compatible browsers and FF being the only one not allowed to use the DUO authentication. I've attempted to clear my browsers cache, fire up FF once more only to arrive at the same messaging. I've uploaded a screenshot of what I ran into.

This has to be some sort of error as I've been utilizing FF and DUO together successfully with no issues over the last year.

Any help is greatly appreciated.

3 days ago I closed my main Firefox Windowby accident, while other windows were open. To restore, I just used the normal "recently closed windows" option and reopened my windows. Immediatly, all my tabs that were assigned to "Containers" were duplicated, and I lost the "Simple Tab Groups" order. For each tab on a container, a second was created without an assigned container. Fine, i thought, just closed 130 tabs that were unassigned, and moved them to the right Groups again. Next day, i open firefox, same thing. All tabs duplicated (but now on the proper groups). Closed 130 duplicated tabs and moved on. But I can't spend 5 minutes each day doing it! Testing more, I realized that every time I close and reopen Firefox, all the tabs assigned to a Container get a copy. If i close and reopen firefox 10 times, i will get 10 copies of all tabs, with no assigned containers to them, ending up with 1300 unnecessary tabs.

I just cant figure out how to fix it. Any advice?

Dear All:

Suddenly FF starts but shows only a new tab without any content. I can fill in a URL but no reaction. Settings doesn't open. Close tab through X Restart FF. no new tab but message: FF is already running but is not responding. The old FF process must be closed to open in a new window. Click to close. a new empty tab pops up without starting FF manually. Close through X Restart brings the same message as above - no window. Have to end FF in Task Manager.

Uninstalled and reinstalled three times - no change.

I'm using Windows 10 and Avast One, Firewall checked - is open for FF.

I appreciate your comments and help. Best wishes Henning

Hello, I need help, it is not possible to open Firefox. After opening, the window closes itself again, a new profile was created, but the problem is still there. I am very unhappy about this. I didn't load a new extension, didn't use new antivirus software. Firefox has already been uninstalled and reinstalled. The problem is not solved. I've also cleaned Firefox a few times, but the problem still persists. There are no crash reports as Firefox just closes and doesn't crash. I can start safe mode. I am sending the Troubleshooting information.

Thanks for your help, Firefox is the best browser! Greetings Silke
