Excellent extension!
It enhances the Firefox Bookmark feature.
It turns it into a flexible tool with many possibilities, of which my favorite is that it allows you to suspend a work session and resume it the next day or even days later without losing anything.
You can also resume by topic of interest, for example, Sundays, friends, etc., without losing the sequence of activity. It's like a bookmark but dynamic, because it follows you like a dog on a walk.
I wanted to make subfolders like stash2025, stash2024, etc.
How could I manage subfolders to make stash perfect?

TabStash is one of those Extensions that should be included in the default browser. Right now my workflow is: current things are on TabStash, long term things are "normal" bookmarks. But that will change soon. This extension has been a life saver and after you try it you won't engage with your browser as before ever again.

Great extension! Thanks!

Is there any chance of making this available to Firefox mobile? Especially Android edition. That would be killer especially if it used sync like the desktop version.

Best extension hands down. Dev also a goat in terms of support as u can see

An irreplaceable extension. The only two things I wish Tab Stash had are 1) the ability to pin groups to the top of the Tab Stash page and 2) the ability to collapse/expand all the folders in a group with one button. Those are tiny nitpicks, though.

This is the cleanest looking tab stash addon I know. It stays out of the way. You can get all tabs open with one click. One issue though, the new update added a lot of boxes to the tab UI "to make it match Firefox's style"?, and it looks too busy now. The older UI looked better. 5*

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

If the "Save all tabs" option is selected, empty open tabs (without an active domain) are not saved, only tabs with an active domain are saved.
Slow to save 1960 open tabs, no language available support (Italian)

Great app and EXACTLY what I needed as other tab management apps couldn't deliver in terms of management, separation and stability. That being said, I would really love it if there was another way to rescan for titles and headers AFTER importing tabs from URLs. Some of them seem to have failed as I was moving them and the only option to retry the scan is just to retrieve the icons (which it already has so the button does nothing.) Unfortunately, I don't have a github account to reach out with this complaint.

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.
