does not work with Firefox 'tab groups'

I loved this extension, it did exactly what I needed it to, but the "open" button has suddenly stopped working. I tried removing and reinstalling the extension but I have no way of opening sessions anymore. I can only click on each link one by one. If this is fixed, I'll revise my review.

Documentation / Readme is insufficient. Cannot see what the Tab Session Manager is actually supposed to do and how to use it. What makes it worse, is the author's poor command of the English language. In Settings, file paths are not shown, and apparently cannot be set. All in all the whole thing seems too complicated to me. On top, when experimenting to make sense of the extension, it repeatedly crashes and takes the browser with it. A waste of time.

Does not even appear on the toolbar or anywhere else - so no idea if it actually works or not. About to uninstall and find something else.

Did not save my fucking tabs.

Destroying my tab groups every launch. All Tab Groups need to be recreated, all tabs need to be readded to their groups. Disabled until this is supported.

Not restoring previous.jsonlz4

On two different ff versions 91.9.1 and 115.20 it randomly deleted ALL sessions, on one ff i lost a sessionwith 2000 tabs and on the other 1800 tabs, backup is disabled by default, no other backups are kept and recovery is possible only if you have all your history from the past 6 months. evrything else is pretty good.

used to work but recently after the notorious Firefox update it's now broken and author does not respond.

Where the hell are all my tabs!!!??
The settings have ALL my windows and tabs to automatically save and restore... I am missing more than half my windows and hundreds of tabs!!!

Jan-2025 This outfit used to have two extensions - a video downloader and this Tab Session Manager. The video downloader stopped working about a year ago and now the Tab Session Manager has stopped working too. For almost two years, I've allowed them to autodebit my Paypal - BUT NO MORE. When I wrote them about the video downloader not working I never got a response. Adios.

DEAD!

dont work

The extension no longer stores any sessions. Its basic functionality is broken. The last update was almost 7 months ago. Has it been abandoned?

Hasn't been updated in almost 7 months and lots of outstanding bugs on their Github page. They just don't seem to care about this anymore. Look elsewhere.

I just want the pinned tabs to remain open even without restoring the session. This does nothing more than create a more bureaucratic history, just like restoring the session.

It's been broken for a few months now - and nothing actually works.

Does not work. File has the data inside it, yet this add on does nothing with it.

Latest 7.x versions don't work - I lost all my data like many others. I have gone back to the last 6.x version but I am not happy about the loss of data.

Borderline useless. Autosave for sessions does absolutely nothing as I've had to painfully find out the hard way, which makes the whole point of this extension moot.

Still looking for a firefox equivalent of the chromium plugin "session buddy"... and this one here definitely isn't an option if the most basic features just don't work.

Literally the only plus point I've found was that it's able to save and restore private windows, which I use to log into multiple accounts for the same site (rather than constantly switching between them). Hardly worth it if everything else doesn't work properly though
