Extremely good and powerful. I am using it as complimentary add-on for in-built bookmarks system and it has already considered many possible use cases like de-duplication, close stashed/saved tabs, highlight opened tabs, and it even updates order of bookmarks if the actual tabs are re-arranged before saving! I also recommend setting this extension page as homepage so all links are neatly organized and accessible. This wouldn't be possible without this add-on, anyone used to papaly will know exactly how useful this is. Also you can import links and file structure from copied list of bookmarks.

works as a Side Bar in LM22.2

The name of this extensions is not wrong, It stash's tabs. Out of all the extensions I tried (and I tried alot) this does it the best. Yes the setup is a wee bit confusing but once that was sorted I managed to get it working exactly how I wanted it too. This should be a base firefox feature, Idk why it is not already (needs to be part of firefox view).

The only one thing I would like to see (other then it being part of firefox view) is the ability to select multiple tabs in a stash and export them to a file (for sharing else where)

Edit: the dev responded and I am embarrased I missed the setting to import and export, It literally is the exact addon I was looking for. Now my firefox actualy loads fast.

I'm in love with this extension! Would love to see it on Chrome based browsers too (please port it, I desperately need it lol)

best tabs add-on I have used so far.

非常好用

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!

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.
