At some point a few days ago I accidentally dragged the divider that separates the pinned and vertical tabs. As a result, for the last few days, I have been stuck with the divider being in a fixed position no matter how hard I try. The problem is that I use collapsed sidebar by default and can't reposition it for the collapsed tabs state, and as a result, there's a mismatch in how many pinned tabs I can see when hovered and when unhovered, among other issues

If possible, I'd love to just reset the position to how it was before, that being that it would show maximum pinned tabs and scroll the normal tabs, and do so for both collapsed and uncollapsed tabs, but I haven't found a way yet

I've tried dragging the divider to the very bottom, but that didn't work either and it'd eventually reset

I would like to make Firefox web browser to save automatically the "tab group" created.

The feature is already there by left clicking on the group and choose "save and close group". I would this to be automated as default behaviour at every attempt to close the last tab of the group, so the "tab group" never gets deleted by itself. Only deliberately left click on the tab group and choose "Delete group".

Thank you in advance for your time reading this. 🙇

Latest Stable Firefox, windows, over 4000 tabs. Overall Firefox works great for me. but when I restart it to install the latest versions etc, it only restores one active/loaded tab per window. Rest are restored, but in a closed/unloaded state. I usually have 5-20 open tabs per window, and hundreds more unloaded, it's how I work. How on earth can I get it to restore all the open/loaded tabs as they were, not in the unloaded state they default to?

Issue still occurs in a new install with no addons, default settings, under 30 tabs etc. Ditto Win 10 or 11.

Also, how on earth can I get official Mozzilla pages to use Dark Mode??

How can I make sure the Vertical Tabs sidebar stays visible in full screen mode?

It worked this way by default until the [154.0 release](https://www.firefox.com/en-US/firefox/154.0/releasenotes/#note-792047):

> Fixed the Vertical Tabs sidebar staying visible in full screen mode. It now hides along with the toolbars and reappears when the cursor moves to the edge of the screen.

Is there a config setting that re-enables the old behavior? I want the address bar to be hidden in full screen mode, but not the Vertical Tabs sidebar.

Tonight when I launched Firefox, I started getting everything opening in a new window, rather than a new tab, which is what I have indicated in settings and have always had before. Even if I drag a tab from a new window to a previous window, I cannot close the tab. All I can do is close the window.
