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.

There doesn't seem to be an "Other " or "Additional Options" category, so if Settings isn't in the correct category, please tell me where to post this. TIA

I want to be able to create multiple default 'pinned" tabs that will appear every time I open up a new window. Is that possible? If so, how? Again, TIA

Despite re-installing Firefox sidebar is still missing (I spent 3 full days trying to fix it before re-installing). I also can't obtain another tab - I'm restricted just to the one page I'm currently using

This is new behaviour. I havent been playing with the settings, so I imagine its come as a side effect of an update...?

Very frustrating since I have come to rely on having 6 permanent tabs which I use every day for new, prices, weather etc...

I think this started 1 or 2 days ago, after a Firefox update. When clicking on a bookmark and using "open in new tab", anew tab isn't opened. The wanted bookmark page just replaces the earlier screen, and no new tab is made.

Sorry if this problem have already solved before.

After update 158, I've noticed change of closing tabs when it involve unloaded and unopened tabs. I'll try my best to explain: Pre-update 158 - For example, I have 3 tabs. Left-hand is an unopened tab with coloured icon and no image preview. Middle one is I'm currently on. Right-hand is has been opened but I unloaded it; it has grey icon. When I close the current tab, the browser moves to tab on the right and loads it. This is usual behaviour since I started using Firefox long time ago.

After update 158 - Same example as above but when I close the current tab, the browser moves to one on the left instead.

This change means that the browser no longer moves to right-hand tabs if they're unloaded unless if I choose manually. Also, if I have 4 tabs but #1 is unopened with coloured icon, #2 is unloaded with grey icon, #3 is current tab and #4 is unloaded with grey icon. If I close the current tab, #3, it goes to #1 automatically.

So is there something in config to restore back to previous behaviour?

After recent updates there is a line in my open tabs list, currently below the first five open tabs. Why is it there? How can I make it go away? I'm using MacOS 11.7.11, Firefox 158.0.

After my macbook pro (Sequoia 15.7.7) restarted, every tab in both of my open Firefox windows were moved to a *tab group in a single window.* The tab group's name is the date—e.g., "2026-10-11 10:50 *". Right-click + `ungroup tabs` does nothing. If I open a new window, it automatically has a tab open in a tab group with a similar name. I can't move tabs into new tab groups. I hate this. I've lost all my previous tab groups, which I use to organize my work and hobbies, and now that's all gone. I've experienced this on TWO macbook pros. I also have a Windows 10 desktop, but that continues to work as expected.

Months ago, I disabled all AI features, and, and so in `about:config`, I can observe that `browser.tabs.groups.smart.*` are all set to false. I also just tried setting `browser.tabs.groups.enabled` to false, but it had no effect.

See title. On ultra-wide, I would use split view with 4 or 5 tabs regularly if it was available. Please consider adding that function. Also, please add a dark mode to your support site.
