Firefox Community Forum

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

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

I had to restart my computer for updates so I clicked on my container and closed it thinking it was like closing a program and then re-opening it. Now it's gone and several hours research with it. Is there any way to restore a closed container?

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!
