At some point you may find yourself wishing you could get your firefox boomarks from an old profile still resident on your laptop, but no longer the one that you’re logging into.
For example, I have an old profile here for user matthewbradley, but upon getting my account reactivated, I’m now finding myself logging into matthewbradley.UK – i.e. same human, different local profile on the laptop.
The frustrating thing is that all my bookmarks are in Firefox in my old profile and I want to be able to back them up and restore them into Firefox in my new profile.
This is the location in the filesystem where the Firefox bookmarks are kept. Firefox appears to retain backups of the bookmarks on its own, which is very convenient indeed. You should be able to access it via Explorer or Cmd console.
C:\Users\matthewbradley\AppData\Roaming\Mozilla\Firefox\Profiles\jrc8wnze.default\bookmarkbackups\
Note that AppData is a hidden folder so if you’re using Explorer, you’ll need to change the View options to show Hidden Items before you’ll see it.
Simply copy the most recent file to the same location in your new profile. The filename is fairly cryptic looking, e.g.
bookmarks-2018-09-13_15_AWyxn1GRB8WngmWVnMswTg==.jsonlz4
so my advice would be to not change it at all, just copy it as it is, into your new profile.
You’ll need to restart firefox before you’ll see it as a recoverable item in the Firefox Bookmarks, Show All Bookmarks, Backup and Restore dialog.
In newer versions of Firefox, the menu bar and bookmarks toolbar are missing by default (I hate all this modern minimalism as it smacks of form over function) but you can enable it again by right clicking on a blank bit of GUI and selecting Menu bar and Bookmarks bar (Highly recommended).
