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.

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

when I save one session it removes the one I saved previously. exporting sessions stopped working because of some error with website name characters or something. useless. could be suspended tabs issue. doesn't get updated ever. bugs don't get fixed ever.
seriously remove this t from the browser. it's outdated and not being updated. crashes after few uses and you can't fix it there are no easy workarounds. why keeping this useless extension in browser

As others already said: it's completely useless. Autosave is silently failing, restoring manually saved session is practically impossible (at best you can reopen individual tabs) and it may randomly wipe your entire history of saved sessions. Then under Wayland desktop session even button to manually save a session disappeared and shortcuts do not work. The only way to do anything was opening it as tab where button came back. Also, "export sessions" button does nothing.

I can't import my tabs from Session Buddy, I get "Read failed" every time I try. Tired to save and import individual sessions to see if it will work, still not importing.

Worked great for years until after a recent update, it deleted all my saved sessions. On another device, not only are my saved sessions gone, but it now keeps saving every single browsing session on its own?

It opens tabs slower than native Firefox session. And when I switched it off to try working without it, all the tabs except "New Tab"s disappeared. What is the use of "session manager" if it just loses your session?

THIS GARBO ADDON REMOVED ALL MY SIDEBERY TABS, "open in current window" YO ASS, THIS WAS NOT "REPLACE"!!

old review:
if you throw donation prompts in peoples faces, they arent gonna like you

Worked fine for years but suddenly stopped doing what it is supposed to. Opened FF and last session did not load. Go to load session manually and all saves have disappeared except for one from three months ago. Won't import files. Won't export files. Won't autosave. Manual save works, mostly, but consistently deletes all but last save. Developer obviously doesn't give a crap because this issue has been going on for a while and he/she hasn't responded to any of the many reports, yet can and will respond to random, non-extension breaking things.

Useless.

My last autosaved session is 2024.01.18. After that it stopped autosaving. In other words: unreliable, therefore useless.
It always was slow, but at least it did what it was supposed to do. But now this changed. Used it for years, now I have to look for something I can rely on.

Also compacting sessions deleted them all.

Piece of garbage!
Will never understand, why when a product is working it has to be used as a playground where the developers want to show how good programmers they are and in the end fuck it all up.

This extension originally worked great. I could save sessions, restore whole sets of windows and tabs, etc. For some time now, this extension has become useless. It does still save sessions, and I can open individual tabs again, but it will not restore windows or whole sessions again, which is the whole reason why I installed it. I now have to click each individual tab listed to open them all back up again. Such a pain!

Until this extension works properly again, I cannot use it at all. Went from 5 stars to 1 star.
