No feature for auto backup I can loose all tabs any time

Hmmmm. I so wanted to like this add-on. On the surface it provided a very easy way to organize tabs while not having to specifically bookmark them. You could create separate categories for each group of tabs you had set aside. Such a nice feature.

However, the reason for the low rating is despite how useful it could be theoretically, it really was a CPU hog. I cannot count how many times I had to force quit out of Firefox because Tab Stash was so hungry, my whole computer would die to a crawl. And if that couldn't be done I would have to resort to restarting.

It took me a while to figure out what it was that was causing this. When I discovered that Tab Stash was behind it all I then shut it down and with that everything returned to normal. But I was pretty disappointed in this. As the add-on really made life easier when it worked.

I thought that when tabs were stashed aside, they not only became inactive but were automatically turned off or unloaded so as to free up memory as well as release itself from eating up CPU. But despite there being numerous ways to set Tab Stash to do just that, it really didn't seem to have any noticeable effect. I gave up after being held up one too many times and having no choice but to restart my machine. There are just days when I have no time to mess around with things that make themselves more of a problem then they solve, and it was one of those days, so I ditched it. And with that, my system went back to normal, I was able to scoot about on the net as before, and outside of losing all my stashed tabs (so I thought) I could carry on in my normal fashion.

Later, I discovered that Tab Stash is nothing more than a clever UI that deposits all those stashed tabs in its own bookmark folder it creates within the Mozilla Bookmarks Menu.

Having discovered that, I simply continued to use that bookmark folder opened in the side bar where Tab Stash once sat. A simple Ctl-D and I can stash my tabs in that same folder, and then do with them what I wish at a later time. Sure, it doesn't have all the pretty functions up front, but I needed Tab Stash to do the most basic of things, which actually was the primary purpose for such an add-on in the first place. Failing that, I found doing it the old fashioned way utilizing Firefox's side bar, sufficed AND without hogging up CPU or decimating the memory.

Sometimes simple is best.

Fantastic but would love to be able to rename tabs. I use it for a website that every tab is named the same, in Microsoft Collections I can rename everything, but really want to come back to Firefox. I love having the side bar and being able to navigate groups in a simple compact way.

Usability wise quite complicated, this add-on mixes the concepts of tabs and bookmarks, which as such is an interesting idea, as most people use tabs as a kind of bookmark.

However, my greatest problems with the add-ons are
a) usability (I just don't understand when a tab is just hidden, when it is closed and re-opened from bookmark)
b) performance (unstashing re-opens tabs one by one which can easily take 20s for lots of tabs)
c) loss of history (actually the tab is not stashed, only the open URL)

The loss of history is my biggest problem which finally caused be to uninstall the add-on. A tab is often worthless without its history.

Sorry Josh, I really wanted to make this work, but just 'don't get it'. If you could offer a better User Guide I might be able to understand, but as it is 9.30.22 I can't get the hang of it.
I have a load of tabs open, and want to sort them into different groups of interest, but couldn't find any instructions that helped me get the overview.
I'm sure it's really good, but not without a decent User Guide, TY.

I really like the app, however it is using up way to much memory, and this is on a high spec MBP that's less than a year old. As soon as I disable the extension, everything goes back to normal.

Potentially a great extension, but I have the same problem with high cpu activity that others have reported. I don't know if this is a coincidence, but I only have this problem on Windows 10; on my Linux laptop I have no such issue...

This addon does not have confirm dialog before stashing all your tabs, and doesn't restore the tab forward/backward history after unstashing, you have been warned.

The extension is great if you're just starting out and have nothing to import from one tab OR you have few tabs to import. But if you like me have 5000+ tabs from one tab the importing process not only is a pain because it has to open each tabs sequentially, but it doesn't even work.
It just stop importing while still opening and closing tabs while stashing nothing.

The extension is great, and the best part is that it syncs across devices BUT again: it's nice only if you're new and have nothing to import

I can't see how to update the group; if I have several tabs, I save them to a group, then I load tabs from this group and let's say delete a few tabs, the deleted ones are still in this group, creating a new group every time I close the window would be time consuming when I have over a thousand cards process lasted a dozen minutes, I can also manually remove a given tab from the group each time I close it, but that would also be inconvenient, is there any solution?

EDIT: today i lost my session, i tried to restore a saved copy with this addon and it failed, firefox crashes because this addon refreshes every tab it restores and the program can't do it with many tabs, even with 100 tabs its too long

Great idea but as other reviews have mentioned, there are a few annoying UI issues. I'd love to use this addon, the sidebar is way better than using OneTab. But as I was testing the addon, by importing 65 tabs from OneTab export file, it couldn't do it. The UI issues also made me loose a few tabs. I hope development continues and the addon improves. I'll keep it disabled but installed to keep an eye on future releases.

Great idea, but UI really should do some rework. I managed to accidentally lose big chunk of tabs in the first minutes of using this extension, and there is no undo. It's so easy to stash/remove from stash - even groups of hundreds of tabs - and as you click, position of buttons change, opening to accidental click to delete whole group.
I would love an extension like this, but which took tabs more seriously, and made it harder to lose data. Also, I really missed option to export and import all stashed tabs.
