Installed this a long time ago and forgot it was there. Today, Firefox lost my open windows history and I was panicking until someone reminded me about this extension. I used it for the first time and it rescued everything!! Thank you sienori!

I love this extension. Thanks for your efforts!

I've used this add-on running pretty much in the background for years and the auto-save feature saved my butt from accidentally closed windows a few times. It was like a nice browser session insurance policy. But the user saved sessions feature combined with the new*** tracker feature is just brilliant. Now this add-on is saving me from a personal multi-opened windows with multiple tabs hell and has become a legit sessions manager for me. And the sync feature to Google Drive continues to be rock solid and one of the few add-ons that does it correctly (it just works). I just donated to the dev so I'm putting some money where my mouth is. ;-)

***Well I've since discovered this feature was released in May of 2022 so I guess it isn't as new as I thought (which was Sept. 2023). And it has some quirks around sessions opening at startup where you have to close the session and re-open it to get tracking going. I'm more concerned there haven't been any significant updates since Sept. of 2022 and I hope the dev isn't slowly abandoning this project. :-(

I use this as a solid capable reliable method to save my Tabs and store different Sessions. Brilliant, useful, practical, Solid.

A very useful and easy to use extension, which does exactly what it says it does.

Absolutely necessary. Adds functionality that FF should have out of the box. And does it quite well. Also the only tab manager across multiple browsers I've had no issues with. Can't recommend this enough. Though it doesn't always save correctly on closing. Just manually save before closing. Shame, but at this point I'm not even knocking off half a star for it.

Saved me today, fuck
