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.

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.

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

Context: In the customize sidebar section, if the "Vertical tabs" checkbox is checked, the vertical tabs can be switched between showing names and favicons, or just favicons. If, additionally, "Hide tabs and sidebar" is checked, then vertical tabs instead can be switched between showing names and favicons, or being completely hidden. (These settings are in the photo I uploaded)

The recent update seemed to add a feature I had been really wanting from vertical tabs. I could switch between all three states: favicons and names, just favicons, or completely hidden. I could do this by dragging the vertical tab pane smaller or bigger. A few days later, though, it stopped working, but I didn't change any settings (as far as I remember).

Is there any way to get the three-state vertical tabs back? They were really nice!

When there is a crash, update, or restore session, my Firefox windows do not restore in the same task bar order that they were beforehand, which is very important to me for workflow. I need to change the links to all the open windows. At least it would be great if I could drag and drop the the windows to re-order them. With frequent updates by Mozilla and Microsoft, it would be really helpful to get this fixed.

When I open many new tabs, I'd like them all to be loaded immediately (as soon as they the new tab is created, a.k.a. eager loading). The reason is that, when I click to actually see those pages, if they are already fully loaded, that will make user experience much smoother.

Please see attached image for a demo of current behavior: browser had plenty of time to load those new tabs in background, but it didn't.

I understand that lazy page loading is a way to preserve RAM and CPU cycles. I know that is usually a good thing for users who are used to working with only one thing at a time and/or have limited hardware resources. However, I think there should be an opt-in feature of eager loading, which would optimize a lot the time for experienced/heavy users.

Thank you!

Hello, where does one find the option to return old tab folder look?

These bubbles look ridiculous and remind me of the 'corporate art'. As a long time user, my heart just cannot accept this. I was on the verge of crying when I saw this on my PC (I have been actively avoiding this update after seeing it on my laptop). I have looked everywhere in the settings but did not succeed on my own.

Would greatly appreciate the help before I double my OCD medication norm
