Rated 5 out of 5 stars

The developers of this addon not only provide something that to me every single browser should have but have managed to enhance it. That usually isn't the case when you add on to something that in its simplest form tends to seem flawless already. No more copy-pasta of every open URL into a sticky note!

It's like the first time I saw an electric toothbrush--in this case maybe after I'd been scraping them with my fingernails for a year out of laziness and thinking they were passable.

I really, really don't like to speak so sarcastically and negatively about FOSS apps, let alone something that is an impressive and involving as Firefox, but even if this only added two keyboard shortcuts to save a single session of URL's to a flat text file and to open them back up, it would still get five stars from me because that's still more useful to me than the current somewhat similar options.

I assume we will be able to soon but right now one cannot save tab groups (yet can name label them, which I would only need to do if it were the descriptor in a saved sessions folder/menu).

I tried to export my browser history, but I must be missing somethin that indicates it was actually exported somewhere and in a human-parsable form (wouldn't ever do that either, especially if other people used this computer). I know other people have uses for these tools but it's frustrating to have three possible almost-there features that instead of being almosjust things I

Got nothin' but love for *all* the great Firefox devs and contributors; truly, I do. But damn. :P

This review is for a previous version of the add-on (0.7.7.1-signed).
