Your bookmarks can be imported and exported from the Library (Bookmarks Manager).

• Go to the clipboard icon, click Show All Bookmarks OR press Cmd + Shift + B
• Once there, you'll see Import and Backup (see screenshot), you have a choice to choose between backing up as a JSON (Import and Backup -> Backup) or HTML (Import and Backup - > Export bookmarks to HTML)

Once this is done and the file has been backed up, you can import them using the same method (Import & Backup -> Backup for JSON/Import & Backup -> Import bookmarks from HTML (HTML)

One of our awesome contributors explained the difference between a JSON backup and a HTML backup that is very explanatory:

Restoring a JSON backup will replace all your current bookmarks (you get a warning about that), so if you already have bookmarks that you wish to keep then export them to an HTML file before restoring the JSON backup. You can import that HTML file after you have restored the JSON backup to get your current bookmarks back (you need to remove duplicates). You can't import a JSON backup to add (merge) bookmarks.

Importing bookmarks from an HTML file adds the imported bookmarks to the already existing bookmarks, so you may need to remove duplicates. An HTML backup doesn't support tags and annotations, so if you want to preserve those then you need to use a JSON backup. A JSON backup doesn't preserve the website favicons, so you need to visit a website to get back that favicon.

Thanks for the effort but this only backed up the bookmarks I've added to 29.0.1. It did NOT import bookmarks from 28.0. Any suggestions will be appeciated. (BTW, thanks for the explanation of diff between JSON and HTML.)

For the Bookmarks in 28, you have to use the instructions below to export them from 28 then import them into 29

• Go to the clipboard icon, click Show All Bookmarks OR press Cmd + Shift + B
• Once there, you'll see Import and Backup (see screenshot), you have a choice to choose between backing up as a JSON (Import and Backup -> Backup) or HTML (Import and Backup - > Export bookmarks to HTML)
  • Once you choose how to back it up (JSON or HTML), you can use the Method below to restore it based on what file format you backed up the bookmarks in 28.
  • If you backed up using JSON, you can restore this by going to Import & Backup -> Restore. If using HTML, you can go to Import & Backup -> Import bookmarks from HTML

BTW your bookmarks should have already been imported if you upgraded from Firefox 28 to 29. How did you update?

• See Recover lost or missing bookmarks for more information.

Firefox doesn't change the profile folder when you update Firefox, so all your personal data should still be there.

Make sure that you still use the previously used profile folder because it is possible that anew profile folder got created because of issues with the profiles.ini file.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

If you use the Time Machine on your Mac then you can try to restore your personal data from that backup.
