Bulk edit Firefox bookmarks

The company where I work have changed all corporate URL from subdomain.domain.com to new.domain.com

I would like to change the subdomain of all my bookmarked sites in Firefox which are a lot.

Is it possible to change all of them in a row instead of manually editing?

I don't know if there is a better solution but this hack seems to works:

First locate the bookmarks file:

• Go to Help -> Troubleshooting Information and then click the "Open Containing Folder" button near "Profile Directory".
• Do a backup copy of places.sqlite.

Then edit bookmarks:

• Close Firefox.
• Edit the file places.sqlite with a SQLLite editor of your choice (you can use online tools).
• Execute this SQL statement:
  • UPDATE moz_places SET url = REPLACE(url, 'subdomain.domain.com', 'new.domain.com');
• Save the edited places.sqlite file.
• Open Firefox.
