If like me, you've ever accidentally deleted important bookmarks out of Firefox you know that sinking feeling and no, they don't go to the Recycle Bin.
However help is at hand with the built-in recovery system. In Firefox go to the Bookmarks Menu and select 'Organise Bookmarks' or simply press CTRL-SHIFT-B..
In the 'Library' window, click on 'Import and Backup | Restore and select a date to restore from.
A warning advises that any new bookmarks subsequent to that date will be overwritten..
Yet another good reason to be using this fine web browser. Thanx Firefox - you're the best!
