Automatically hides your Firefox bookmarks in the toolbar

Do you like the Fiefox browser? Here is a trick to automatically hide the bookmarks toolbar in Firefox, only when you move your mouse over the toolbar, just like the automatic hiding taskbar effect in Windows.

To do this, just edit your Firefox user profile userChrome.css and add this code (it's best to back it up before doing this) :

/* Pop-up bookmarks toolbar */ #PersonalToolbar {display: none; } #navigator-toolbox:hover > #PersonalToolbar {display: -moz-box; }
