Fresh migration from Win 11 to Mac. tabs, passwords, bookmarks, plugins migrated from win to mac. Attachments:

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've been trying to decipher browser.tabs.insertXXX with little success. What I want to achieve is to open tabs from the same site next to the current tab with the most recently opened tab next to the original tab.

Example Two tabs are open, site 1 tab 1 and site 2 tab 1. Open a new link to site 1 on site 1 tab 1. The order is site 1 tab 1, site 1 tab 2, site 2 tab1. Open another link to site 1 on site 1 tab 1. The order is now site 1 tab 1, site 1 tab 3, site 1 tab 2, site 2 tab 1.

Thanks in advance.

I can't save my tabs & windows anymore, I have the box checked but after I close down the computer I lose all the tabs when I reopen and then I need to put them all back manually. What has gone wrong it always worked before for many years? Please tell me how to fix it

Good evening. I have had to install my FF after a system repair. I have everything set back except when I click on a link and hightlight an item with my mouse and right click it opens a new tab. But before where it would just open it changes to the new tab immediately. Under settings I have the 'when open new tab switch to it immediately' unchecked and I was directed to four settings on about:config including browser.tabs.loadDivertedInBackground to set to true. I did and the behavior did not change. Any suggestions would be helpful. Thank you.

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

When I start MF, all tabs I have used before open. Good! But one of these tabs are not in use. That it why I want to close it for ever.

The option to delete it for ever is not available.

Grateful for your help!

When using vertical tabs layout with "expand sidebar on hover" setting enabled, sidebar scrolls up with each expansion, so that when hovering over a certain tab of collapsed sidebar, another open tab is under the mouse pointer when expanded. For additional details please refer to the attached video.

Steps to reproduce: 1. Enable vertical tabs layout with "expand sidebar on hover" setting 2. Open a lot of tabs 3. Hover over a certain tab

Observed result: The sidebar expands with mouse over another tab and the list of tabs scrolled up.

Expected result: The sidebar expands and mouse pointer is hovering over the same tab after expansion from collapsed state.

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

when I click a url link from mail it opens a new firefox window instead of a new tab on existing window. I like to keep all tabs in one open firefox window. Firefox crashed last night and lost all of my tabs; I was able to restore but now having issues with email url links opening in a stand-alone new window - HOW do I revert to former option?

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?

Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?
