Hello. For years I've been successfully using your browser. Now it keeps giving messages that say "Try Again" .

We can’t connect to the server at links... bla blah

Server Not Found

...PLEASE ADVISE

Issue Description: I’m experiencing a problem with fullscreen mode while using YouTube on Firefox on Windows 11 with a dual-monitor setup. When I enter fullscreen, the video does not cover the entire screen. Instead, I can still see parts of the Windows desktop or background around the edges of the display.

This issue only happens on Firefox and only when using fullscreen mode on one of my monitors. I have already checked my display settings, scaling, alignment, and hardware acceleration, but the problem persists.

System Details:

Windows 11

Dual-monitor setup

Browser: Firefox (latest version)

Issue: Fullscreen video shows borders and does not fully cover the screen

Expected Behavior: The fullscreen video should completely fill the selected monitor without showing any part of the Windows desktop.

Please advise on how to resolve this issue.

Hello I have an issue going on with the autofill info that I use. When I type my name, my 1st name comes out fine but when I type my last name it's now a misspelled last name. Seems like it all started with a new banking company that I'm with now. I 1st notice it there and I had to fill out forms to correct the info with them and it was kind of a hassle. I noticed that there was one extra letter added to my last name when I looking at my account info. Maybe when I was initially filling out my personal info with them, I might have spelled my last name incorrectly. I'm not sure. Sometimes I type words wrong. I'm not the greatest at typing. But since then I've noticed my auto fill info, my last name, has been bringing up that same incorrect last name. How can I fix that. I see solutions for editing addresses and passwords but nothing about names, personal info. Anybody know how I can fix this. It has become a nuisance. Thank you ahead of time.

trying to update old version of Firefox but seeing error code: ssl_error_no_cypher_overlap and the message "no common encryption algorithm" on a MacBook Pro with OS 10.5.8 - - not the machine I'm using in order to seek help

The installation on my win 11 laptop is doing some odd things (1 - recently lost all extra (unselected) windows on restart, even though set to restore all windows and tabs and 2- opening a new window creates an outdated duplicate of the window I already have open instead of just creating a new window with an empty tab??). So I thought I'd try refreshing it. Well, my "More troubleshooting" page does not have the "Refresh Firefox" button, only the "clear startup cache" appears along with option to run in troubleshooting mode. No Refresh option in teh same page in troubleshooting mode either. I am using the Microsoft Store MSIX installation. I am thinking about uninstalling that one and installing from a Mozilla download instead??

What would be the best way to clean up my installation state since the refresh is not available?

I use the email address [email 2 removed]@interia.pl. The account is configured in Thunderbird on a Lenovo laptop. The laptop is protected by ESET Smart Security antivirus software. As recommended by Eset, I added ESET VPN to my protection. After enabling ESET VPN, the address doesn't configure. It requests a password. I receive messages that the server is disconnecting. Other addresses work. Disabling ESET VPN causes the address to work. This problem doesn't occur on my other Outlook email client. I would appreciate your help in resolving this issue.

Good morning,

I have been using the Dashlane Password system on my desktop for several years and it works great with Firefox, however, Firefox was recently upgraded (automatically) to Firefox version 145. Now I can no longer access the Dashlane application which contains all of my passwords. What should I do to recover my Dashlane application?

cannot access primary email. idiot firefox requires primary email in order to make backup primary !!!!!!!

Unbelievably poor design.

I have a backup email address, recover codes, phone.

but firefox requires the inaccessible primary email address to make any changes !!!!!@!@!@!!!!!

To sync a mobile device, the instructions say to open Firefox browser on mobile, from Menu go to Sign In, aim phone camera at QR code. The 3 lines at the screen bottom right (i'm assuming this is a menu but printing an icon labelled "menu" is less cryptic) offers no sign in opportunity.
