Rated 4 out of 5 stars
MUST HAVE for Firefox. But It disables refresh and back on many pages including Google. You can't go back to the first page, only subsequent pages. If I add an exception in BarTab's options it fixes it (mostly) but it happens on so many pages that almost nothing would unload if I did this, not to mention the PITA. BTW if you repeat your search on Google before going to the next page it also fixes the problem.
I do LOVE this extension.
However, I'm disappointed that there is no tech support. So I had to give it four stars in order for others to easily find my post.
