I like it. Rated 5 out of 5 stars
It's really good for browsing more than one page on the same site. The titles on the tab sometimes look the same and it's nice to be able to actually see what each tab contains. I don't think the previews slow anything down, contrary to what others have said. And my computer ain't exactly new. I just wish you could hide the buttons on the tab previews, or maybe customize which ones you want to appear. But overall, great addon. I get a good deal of use from it.This review is for a previous version of the add-on (0.2.2.10).
