20250607 It does the job as it should! No complaint, till today that it double saves my open tabs. For example, if i have 2 windows and 50 tabs on each, it saves and opens 4x windows and 200 tabs. I use this extension for a long time now (years), without complaint. I don't know if it's firefox's fault or the extension (probably a firefox thing). Please take a look at this Sienori, thank you!

### 20250608 EDIT: I don't know what happened yesterday, but today it seems to be working fine as always, as it should, so i came back to edit the review, because, again, you've done an Awesome work sienori! You 've saved us many hours from being lost! Thanks, and please keep it up!! :-)

I tried Tab Manager Plus but found it USELESS. It doesnt save sessions like it says it does but this one I installed and BOOM, So easy to click on it and choose save session, thank you!

Works really well. I would like functionality to name windows and have that title persisting after saving and restoring a window or session. I'm using extension Window Titler that prefixes the name of the window with [MyTitle], followed by the name of whatever tab is currently open (so window title changes dynamically). That functionality is perfect, but that title is obviously lost when window is saved.

This is an excellent and convenient extension that I've used for years. It has saved me many times when I would have otherwise lost all my tabs. I love that I can create manual and automatic saved sessions and even back up to the cloud or export to a local file.

If possible, I would really love the ability to backup up tab groups. I know that it is a really new feature and I don't know if extensions have the ability to do that, but it would be very helpful.

I think that it would also be nice to have a feature to pin some sessions to the top of the list to make them easily accessible.

After several months of using I can say: Absolutely Vital. When you don't want to close a window (just in case you possibly would miss the tabs), save the window instead. No more gazillions of windows, and no tab is lost.

das beste Addon zu Sessionverwaltung in Firefox und Opera Web Browser!! Benutze es seit mehreren Jahren in Firefox und nun auch in Opera - absolut zuverlässig und unglaublich simpel zu bedienen.
