no but you can do this to get back your bookmarks:
Bookmarks > Manage(or Organize) Bookmarks > File > Import > From File
Type "%APPDATA%" in the file field and press enter.
This opens the Application Data folder.
Go down into Mozilla, then Firefox, then Profiles.
This is the parent folder of your profile. You should see a folder called xxxxxxxx.default ... xxxxxxx is a sequence of numbers and characters. It's random and weird looking...
In this folder you will find the bookmarkbackups folder. Go in that and select the file with a date before the date your bookmarks were deleted
