Been using for years, great add-on. But now affected by the new Firefox sidebar that appears alongside and can't be removed.

Great that this was noted 2 days ago (issue #3726 on the support pages) as an "enhancement" in triage. Hopefully its a top priority! It says "collapse the side bar manually" but everytime I do that TST also closes?

Very good, a lot of tabs can be located faster, the same tabs open pages are also organized together!

Great for managing tabs and tasks and research and group them and…

I can't live without this add-on. This is an essential Firefox add-on for me. Great job!

Only drawback: It makes it very easy to have too many tabs open. :-)
