By default firefox saves your bookmarks to
You can see there a bunch of *.json files.
bookmarks-2010-07-07.json bookmarks-2010-07-29.json bookmarks-2010-08-03.json bookmarks-2010-08-05.json bookmarks-2010-08-06.json bookmarks-2010-08-10.json
If you use more than one machine or you’ve recently changed / reinstalled your OS and you want to restore the old bookmarks, you need to import them manually:
- backup your bookmarks files to a safe location e.g.
cp -r ~/.mozilla/firefox/*.default/bookmarkbackups user@other_machine:~
- on your new / other machine, open firefox then go to Organize Bookmarks
- go to Import and Backup –> Restore and choose the most recent file from the list of *.json files that you previously copied
That’s it. You can now use your bookmarks. There are, of course, other (more elegant) solutions such as using a browser addon (e.g. Xmarks) but some people are concerned about privacy, or they just don’t want to complicate things.
