I tried Sidebery for a couple of months off the back of multiple recommendations and while it has some decent features, I found it surprisingly lacking in terms of basic features like "close multiple tabs". I also found it regularly would semi-regularly prevent me from clicking on tabs which was frustrating until I restarted the extension or Firefox.

In the end I found good old Tree Style Tabs was better. I just wish it had an easier UX for creating named tab groups.

I use Sidebery a lot and I'd like to know what exactly you mean by "close multiple tabs"? I currently drag with right click in Sidebery and then click close tabs in the popup menu, however I don't really like doing this way. How is it done in Tree Style Tabs?

I have TST set up thus: closing a tab will close all its child tabs, if that branch is collapsed. Pretty sure Sidebery can be configured the same way.

Oh! As another Sideberry user thanks for sharing this. I usually Ctrl+click or Shift+click tabs before middle mouse clicking to delete all selected.

In Tree Style Tab, you can shift-click to select a contiguous range of tabs and then use the right-click menu to close them all.

Try Simple Tab Groups. Been using it in conjunction with Tree Style Tab for a long time.

Tab Mix Plus is the OG GOAT of tab management. Its claim to fame is that it’s still the only add-in that gives you multiple tab rows.
