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

I started using a tab group to organize my tabs and save it. I was able to open it from the overflow menu before but now there is no trace of it there. Surely there is a way to see the history of tab groups and recover it right...

please allow me to stop firefox for making tab groups. I already checked the setting "Use AI to suggest tabs and a name for tab groups" but you don't have a setting that eliminates tab groups altogether. these tab groups keep popping up and messing up my tab organization. thank you

The website wouldn't open for me, so I decided to restart Firefox, after which it closed all my tabs and tab groups. My settings are set to "keep tabs after closing the browser." This hasn't happened before.

I use Tab Groups quite frequently. I am not a fan of the new functionality built into it.

So now if I close a group, one tab within that group will stay open if I was just on the page. It will not close until I go to another page and click close on the tab group again. Frustrating! Why cant I just open and close as usual?

Is there a way to get rid of this feature and still keep tab groups?

Is there a way to disable tab groups without going through about:config? Because I can't find it and there really should be...I have no idea how that feature works, I don't want it, but I keep ending up with groups unintentionally. I still don't know how I'm doing it. It's incredibly annoying and apparently incredibly easy to accidentally trigger and I'm sick of losing tab space to these random colored boxes for no apparent reason!

I have vertical tabs turned on. Say i want to watch a movie, i press F11 or fullscreen to open it fullscreen. It makes the whole page fullscreen, but the vertical tabs remain still on the left. I want that fixed so that vertical tabs are hidden when its fullscreen.

I have the same issue as this person https://support.mozilla.org/kn/questions/1373153. I HAVE the "Open previous windows and tabs" option on, i also DON'T have the "Clear history and cookies when closing the window" nor "Clear history when Firefox closes" nor "Always use private browsing mode" on so the solution doesn't work for me. Firefox won't open previous tabs when i close the window. However upon restarting my PC i have noticed that when i start up Firefox, my previous tabs are opened. So it seems the action of closing the window is doing something to prevent Firefox from opening the previous tabs again.

dear sir/ mam:

like in safari, i had pinned the websites (as tabs) i visit regularly.

when i restarted the browser, all tabs were gone.

i have been using this feature in safari since a decade and no pinned tabs have been lost.

please guide.

I have an issue with grouped tabs but I know where the grouped tabs are, I click the arrow facing down and it doesn't show the grouped tabs that I had, I don't know if it's because I turned off my PC when firefox was still open but I do that most of the time, when I opened firefox it said that it couldn't restore previous session or something like that and next thing I notice is that all my grouped tabs are gone. Is there a way to get them back?

All of a sudden Firefox stopped reloading my previous tabs when I start Firefox (whether or not it is set to open automatically on start up). I have ensured the relevant boxes are ticked and I have even reinstalled Firefox altogether - and all to no avail.

I am using Firefox on a W11 64 bit desktop. I have used it for years and have never had this problem before.

I had about 15 pinned tabs - unloaded - that I was saving for a research project. I shut my PC down and when powered up for the next session - all the pinned tabs were gone. I never thought to record the tabs via screen shot or something.

Is this normal - what are the limits of pinned tabs ? Do they expire in a day ? When the PC powers down ? When Firefox updates ?

Exactly what are the limits or boundaries for pinned tabs ?
