AMO bring back favorites and collections

Mozilla made this dumb move to remove the favorites and collections buttons from the add-on detail pages, because "they're not used very often". This userstyle reverts this dumb move and brings back the buttons where they belong.

Alien Tech Firefox Add-ons - boosts for FF 3.1+

This style adds extra glow effects for Firefox Addons site ( It can be used without Alien Tech Firefox Add-ons (unified version) (best when both are used), but remember it only works with Firefox "Minefield" 3.1-alpha-pre or later. Text-shadow has been supported since the first nighlies, so why not have fun with it ? Firefox 3.1 has been renumbered as Firefox "Shiretoko" 3.5 in latest betas, so this style will work for both. This style has been updated to match v1.4 of Alien Tech Firefox Add-ons (unified version) . More info and compatibility check, see: Full Alien Tech version history is available at You can disable stylesheets to see screenshots in their original size. Please don't rate without comment ! ^^
