Rated 2 out of 5 stars

I have created auto-save sessions dozens of times telling it to save every 30 minute, and it works for some time but then it suddenly stops auto-saving.

I had another firefox crash recently and the newest backup was made more than 3 days ago. So I had to revert to this even though I remember creating an auto-save session very recently. Really annoying. Not sure if you have to create a auto-save session every time you restart Firefox or what, if so that's kind of unpractical.

This review is for a previous version of the add-on (0.8.1.8).
