Rated 4 out of 5 stars
When I upgraded to FF3, I missed these tabs on the "Page Info" window. I'm glad this add-on brought them back. Unlike another reviewer, the lack of proper icons for these tabs doesn't matter to me. My primary computer is a Mac and I use a minimal theme for FF, so I don't see icons anyway. What I would like to see are tabs for the scripts and stylesheets on a web page. I don't remember if FF2 did that natively or if I used an add-on for that, but I used to have that feature and I miss it now.This review is for a previous version of the add-on (0.7).
Grouping scripts and stylesheets
You can group scripts and stylesheets using sort by type-column on Links tab.
