Do you like to autohide toolbars such as the Menu and Status Bars to conserve screen real-estate?
If you’re able to autohide the other toolbars why not the Bookmarks Toolbar as well?
After
As soon as you have installed the extension it will automatically start working.
As long as you hold your mouse anywhere over the Bookmarks Toolbar it will remain visible.
Note: Depending on your theme the trigger area may not be as tight to the Address Bar.
But the moment you move your mouse away the toolbar starts disappearing…
Totally hidden again until you need it.
More autohiding goodness is always a good thing.
This extension is worth trying even if you love to keep all of your other toolbars visible.
