A mandatory Add-on for me. Was better before Quantum update of firefox but with CSS edits you can get some functionality back.

I’ve come to rely on this so much that I don’t even know how people live without it.

Firefox v. 73.0.1

I'd love to give this five stars but I have one major problem and one suggestion:

*I've found TST crashes the browser pretty reliably and Firefox can't restore my session. I'm a serial tabber so losing 100-200 tabs that I accumulate over the course of a week or two kind of kills me. The only thing I've found that might be helpful to users/in troubleshooting is that TST crashes far less when only one window is open. I'd say it crashes every 15 min - 2 hr when multiple windows are open but less than once a day if only one window is used. Also, one window only is far less likely to wipe your session.

*Search function: Again, as a serial tabber, I'd love a search function to find a tab quickly. This is especially true since crashes often wipe the session. opening all the tabs again, combined with the nesting feature - I think it'd be very helpful.

THANK YOU for creating this extension. I hope I didn't come off as ungrateful with my criticism. Only trying to help. Cheers!

Absolutely essential. The lack of anything like this on that other browser makes it impossible for me to consider switching, ever. (No, that tabs in a separate window thing is not near good enough.)

best onthe market, it make me cant migrate from ff to another browser...

One of my favourites addon of all times. I keep a lot of tabs open for work and games (between 1000 and 2000), and this addon is a life saver. Helps a lot and let me save a lot of time in finding the tabs I need. Highly recommended.

nice addon!!!!!

This plugin does a thousand different and strange things like open special tabs to just create a fancy tree, and I just want a simple sidebar.
