Bookmark restoration?!

I have deleted a file from my bookmarks- how can I restore it? I am on Firefox and Peppermint 3.

Firefox backs up bookmarks every now and again … but I gather restoring is an “all or nothing” affair

so you can either do a restore from the most recent backup
(in Firefox go to Bookmarks>Show all bookmarks>Import and Backup>Restore>most recent date)

Or for hunt through the .json file for the URL of your bookmark and manually re-add it yourself.
(the .json files are located at ~/.mozilla/firefox//bookmarkbackups … therey can be opened in a text editor)

Thanks Mark- did the restore one- I couldn’t find how to do that for the life of me!
