Sometimes, I cannot click on an option on a form (on my up-to-date Firefox, on Windows 11 - help, please! Its usually only when the options are shown as little buttons or squares to tick off. Its not my mouse because it works for the usual mouse works.
I can't enter the tick/click necessary on this form to say "Email me when someone answers this thread" Cheers, Carol

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Bonjour,
depuis le début de la semaine lorsque j'ouvre firefox mes marques pages de ma barre personnelle sont disparu et ne sont pas non plus dans l'historique de récupération. il faut que je "répare firefox" pour qu'ils reviennent. mais le problème revient. parfois plusieurs fois par jour. Je n'ai jamais rencontré ce problème auparavant. J'ai un message de firefox qui m'indique que firefox est ouvert ailleurs. mais je ne sai pas où. merci de bien vouloir m'indiquer ce que je dois faire

Recently I’ve been unable to play YouTube videos on Firefox: “Video unavailable.”
I’ve tried clearing the cache and cookies, and restarting Firefox in safe mode. I’ve disabled “Use recommended performance settings” and “Use hardware acceleration.” Still no videos.
I’m using a VPN and have several Ff extensions - none of them video related.
The problem seemed to start after the most recent Firefox update. YouTube works fine in Safari.
Thoughts?

How can you have an expired session, when there was no session?
How do I get the STAR to turn back to Blue & let me save websites to my bookmarks. It was working fine?

I have 18 shortcuts that I have added to the Firefox desktop, but every time I open a new link, a shortcut is added to the desktop. How do I keep these unwanted shortcuts from being added to my Firefox desktop?
I have left Shortcuts toggled on, since I want to see the 18 shortcuts that I have manually pinned. Fine so far.
I have unchecked Sponsored Shortcuts, but I still am seeing sponsored shortcuts. What am I doing wrong?

In the last few weeks, i cannot read my iCloud emails. It says things like"message cannot be downloaded now" or "cannot move to trash now", so the only way I can consistently read my emails, is to switch to my Google browser, which has absolutely no problem with the iCloud emails Why would this be happening?

I am using Firefox on a W11 64 desktop. Until recently (the most recent upgrade, I think) all worked well. But since then although the relevant box is ticked in settings (aboutpreferences general), on opening Firefox the tabs from the preceding session are NOT restored. This is extremely inconvenient.
Have any others found this same problem? Any work arounds?
