Rated 2 out of 5 stars

Best thing is, I can save entire windows with tons of tabs of researched information. Also, I can retrieve those for later use. Also, it autosaves most crashed sessions, and saves sessions regularly at time intervals I choose. Really useful

But, at one point, Firefox last summer completely erased all my old session manager stuff with a horrid update that removed, not disabled, but removed without my permission all of my . Now, in version 5.2, Session Manager is inaccessable, add-ons, & all the saved windows/tabs in Session Mgr. I had to re-install a new Session Mgr., and start from scratch, with all the old data lost. Now, the latest problem is Session Mgr isn't working in Firefox 5.2, it freezes the browser when I click on it & then nothing works, have to re-boot the browser. I disabled Session Mgr. now, today, and am waiting for this bug to be fixed. Hope this bug is fixed soon. Otherwise, it's the most useful add-on I use & have ever used. Great for college students, high school students, and any kind of professional or amateur researchers who need to do research in their profession, or for their hobbies & activities. I'd give it 5 stars, but this new version of Firefox has disabled plug-ins, Java, Adobe, and all my images don't load.Thanks Firefox, for your wonderful coding these days!

This review is for a previous version of the add-on (0.8.1.13).
