Best alternative I've found so far for having workspaces in Firefox. It can sync between devices too since it uses bookmarks!

Расширение крутое и имеет куча возможностой взаимодействия с вкладками и их экспортом и сохранением. Получше tabs outliner из гугл хром. Добавьте пожалуйста русский язык и расширение будет на 6 звёзд))

Probably the best extension of its kind. I really like this thing so I don't need to keep important tabs open forever.

This the add-on you didn't know you needed.
Well thought out and effective.
Very useful for grouping daily tabs and working tab sets.

Excellent! A bit confusing at first, but after a while I got the grip.

What I like a lot is:
1 - that you can rename stashed tabs and
2 - that stashed tabs stay unchanged since the extension copies an opened tab to the 'Open tabs' group. So: the stashed url does not change while navigating. This is a huge advantage over tabs in tabgroup: they change while clicking on links.

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.
