It just took me all freakin' day to discover where Firefox now stores its bookmarks. I thought I'd share.
All user-centric data — that is, all your preferences, cookies, bookmarks, etc — for Firefox are stored in:
~/Library/Application\ Support/Firefox/Profiles
Inside this folder is a folder that just uses a big long string as its name. Something like:
dswa56xw.default
Inside here is where are the goodies are stored. In particular, Firefox now stores your bookmarks in an SQL database called:
places.sqlite
It actually makes sense when you realize that the Firefox folks are starting to move toward the "places" language to replace the idea of bookmarks, but like I said, all freakin' day I was looking for this.
So there you have it. From my process of elimination straight to your browser.
And don't forget to bookmark this page.
