Firefox Community Forum

When using shift+tab or ctrl+shift+tab to cycle between tabs in a window, firefox will occasional skip across one or multiple tabs. This will also happen when clicking tabs directly with the mouse. The tab that should be selected shows briefly before the browser automatically switches to one of the adjacent tabs. I do not have the setting "Ctrl+Tab cycles through tabs in recently used order" enabled. This doesn't happen for any specific tabs or windows consistently, and it doesn't specifically happen to unloaded tabs.

I would like to disable the recent update at settingbrowser.nova.enabled. The purple-pink colors and rounded corners are VERY hard for me to see. I need the gray background, black writing, and square corners back. Thank you.

Hi, I've three Browser profile, when I get new updates, no matter I at that moment be in which one of them but the update just reach one of the profiles. features like Built it VPN, weather widget and etc does not come to the others two. Please fix this one or if its a problem from me, guide me to fix it.

Password Manager warns about password used in an account exposed in a breach but not what account. Why can't Pasword Manager give any detail on the data breach it warns about. Like what account is breached? Would be very helpful to know what account has been exposed!

In version 157, the favorites icon in the address bar and the download progress bar have turned gray instead of the previous blue. Is it possible to revert these elements to blue?

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with mail.pgsolusi.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

mail.pgsolusi.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

I'm getting this when trying to sign into mine and my fiance bank accounts why Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

i accidentally uninstalled Firefox and lost my session, i have Tab Session Manager but it seems that the uninstallation also deleted the saved sessions in there...

can anyone please help?

Hello,

I’m the developer of SnakeGame.Live , a browser-based multiplayer snake game with mouse steering on desktop.

I would like to understand the difference between Firefox’s F11 fullscreen mode and fullscreen activated through a website’s Fullscreen API.

For a mouse-controlled game, do these modes behave differently when the pointer reaches the top edge of the screen? Is there a recommended way to let players use fullscreen while keeping Firefox’s normal exit controls available?

I’m using Windows 10. I would appreciate guidance on the expected Firefox behavior and any relevant support documentation.

Thank you.

Firefox keeps crashing/hanging on startup. Any other browser I use is fine. Been using Firefox for years and would like to keep using it. This has been going on since August, so I have not really been using it since then. Tried all the troubleshoot steps that Mozilla recommends but still crashing e.g reinstall, fresh install.
