It saved my life a few times already. A few months ago firefox started crashing and losing all tabs on linux, and after I installed this addon I had a few crashes that I survived and had a way to restore all my tabs. A real life saver.

I've only used this for a few weeks but I feel like this add-on has changed the way I browse already. It's wonderful to save sessions for different purposes, like one session of looking at Emulation websites, one session for seeing sites about a certain game/show or another session for my work/email. No longer do I have to keep one of each around to switch to a different kind of browsing and have the associated memory usage. I can open my browser to a single new tab and use session manager to find the session I want to use. I give it 4 instead of 5 due to a IndexDB issue which thankfully solved itself upon browser reboot, it hasn't popped up again but it does pose a reliability issue for the add-on.

Highly recommended, should be a feature for stock browsers in the future IMO.

As one of the early adopters, I have been using this add-on from the time Quantum disabled "Sessions Manager". Over a year, this add-on has come close to the functionality of the "sessions manager" add-on by Michael Kraft. I must commend the dev, sienori on his relentless efforts through regular updates in helping the Firefox community. Kudos to the work! The only grouse I have though is that sometimes, I get the IndexDB erroe which surprisingly, automatically resolves itself in a few days. Can't blame for it. Have a good one dev! Cheers.

Frequent updates & nice, clean interface. Haven't had any problems.

Makes functions more accessible!
