Very interesting extension, but there are shortcomings, especially in terms of optimizations after 1000+ saved sessions it starts to lag, freeze, etc., developers, do something about this, optimize the list of sessions so that when you open the menu, not all sessions are loaded at once, but in parts, or make a page mode instead of scrolling, otherwise it’s a complete disaster with the list of sessions!!!, and by the way, for some reason, the extension works better and faster on Chrome than in Mozilla, but there too, if you save a lot of sessions, it starts to freeze, but in Chrome there is also session-buddy, also good, I recommend it, it’s a pity there is no Tab Session Master analogue for Mozilla.

It would be a very great extension but unfortunately it cannot work together the Tree Style Tab. Yes I know it says it can but it's not true. It can restore the tabs with Tree Style Tab in 1 time of 10 attempts, in other cases I lose the Tree Style Tab settings, what is very annoying and I don't says polite words during that time when I have restore the trees manually. What is not a funny process with more hundreds tabs.

one of th most important addons for FF!
thank you.
BEST: sync with cloud.

The extension would be useful, unfortunately it has already happened to me a few times, that when restarting Firefox the tabs opened when closed are not restored. Unfortunately I lose many tabs that I can not recover and I do not like this, so I have to uninstall the extension.

One of my most used extensions. I wish it was available for Firefox on Android.

Ele funcionava bem há alguns anos, mas não salva mais as sessões automaticamente, seja por tempo, seja ao sair do Firefox, somente salva quando salvamos manualmente - e, mesmo assim, pode manter apenas a última.

Great!

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

Originaly I would had given it five stars.
Sadly I've recently lost multiple sessions. SInce then, I lost all trust I had on its reliability so two stars it is.

Absolutely excellent. Has every feature I need and more, and I never use firefox without it.

Clean and powerful.

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

Great Addon but since I installed the SIMPLE TAB GROUPS (STG) extension, it conflicts with it, and causes errors to my Firefox. Please fix that problem.
