best tabs add-on I have used so far.

非常好用

Be ye forewarned... do not jump right into this or any other open tab manager if you have a lot of currently opened tabs that you expect the extension to help you sort out.
My fault really, but intending to just look around, I hovered & then clicked to stash on a filtered selection. Not seeing a way to pause, cancel or undo; I could only let it run. How bad could it be?
It not only "stashed" the ~500 tabs from the filtered selection, but threw the other 3200 tabs in with. Then to my horror found that it put every single one of the 3700 tabs into "hidden tabs".
I only learned of this after a frantic race to shut down every other process & service on the machine to free up as much of the 32GB as possible, praying that Fx wouldn't crash.
It finally ended, and after wasting a bunch of time trying to find a solution, have now resolved to spending more time cleaning up the resulting mess than it would have taken without the help of the extension.
Badly needs an Undo. Badly needs Select/Unselect All on filtered lists. There's not even the ability to Tap-Space to keep selecting in a list, it's a slog of one-click-at-a-time. Badly needs a setting to only affect what is selected and don't mess with anything else.

I'm sick of this add-on, it lives its own life and constantly refuses to restore the last tabs of the session

I've been a Firefox user since ver. 2 and this is my very first extension review. It's an essential complement to get your bazillion tabs back after an unexpected error or closing the wrong window. Simple and easy to use, thanks Josh!

I hope I could have found this sooner! I got rid of other browsers for this. Now I can have my tabs backed up without worrying to lose them. So I can watch my content whenever I can. Totally worth it!

Good one. I hope for a similar add-on for Chrome...

The best tab organizer on the firefox.

Amazing add-on ! I've found just what I was looking for a long time ! It's a perfect substitute for "Pocket" or "Read it later" add-ons ! And all the tabs are synchronized between devices through bookmarks sync of Firefox !

Absolutely a crazy good addon that is surely the killer feature of Firefox. I am so amazed how quickly and smoothly this addon can manage 1200+ groups and 36000+ tabs across 20 devices. It's simply unbelievable. Thank you so much for this great addon. Great softwares truly can change people's life in such a positive way.

Please add flag to create with old folder name when search is active instead of the search terms
>edit
Instead of whatever is typed in search , i would like the option for folder names to be created as in Version 3.1.1
Search terms as folder names are too contitional , restrictive to work without affecting stash organization even more when having to manage numerous diverse tabs
The search terms can be regex , random , short , ever changing etc ; they ignore the how often a new folder is created that can be set in the addon options when the search term is changed ; selecting and chosing to create a new folder will just do the same and can lead to duplicate folders if the search terms remains the same , at least in this case the folder names with 3.1.1 format would not be identical ; now if technically speaking the search term would check not only the topmost folder in the stash root but check all top folders (not sub folders) then it would just stash in a old folder where in this case the outcome wouldn't be desired so theres no avoiding this issue
3.1.1 naming format didn't had those downsides and was simple to work with
