I just recently updated from Iceweacel 20 to Firefox 30, and gosh! Firefox just ATE the space from top of the browser window.
This little piece however fixed that, as it squeezes those buttons and bars down to nearly nothing. Space save is 1/3 in minimum! (For a note, I keep menu visible all the time, as I *need* stuff from there, often.)
I'd love to give five stars for this (would give 4 and half currently if it was possible), but there's few things that poke me in the eye.
-Simplistic doesn't need to mean ugly. Well, LittleFox is not *ugly*, but it reminds me too much of Win98 era, which I'd love to forget.
-RSS-feed (in bookmark-bar) has same icon for both visited and non-visited pages. This is bad, and the biggest one of the reasons why I dropped a star. Such a small detail may matter a lot.
Anyone having problems with visual conceptualization (correct term?) should keep clear distance, but anyone else who hates it how Firefox's UI is bloated, I warmly recommend this addon.
