Rated 5 out of 5 stars
Amazing theme for Firefox. When I look for a theme for my browser, small and compact is what I look for and this gives you exactly that.
Easy to use.
Small light menus, you can fit all your bookmarks on neatly.
Saves a lot of screen space.
None that I can think of.
If you're looking for a nice small theme for your Firefox, I couldn't recommend a better one.
