For assistance with importing passwords to/from other versions of Firefox see: Tip: Importing Saved Passwords

During the development of Firefox 3.1/3.5 the way Firefox handles passwords was changed. Passwords are now stored in a file called signsons.sqlite. Should you choose to do a fresh install of Firefox 3.5 instead of upgrading directly from 3.0.11 or moving away from the old Firefox 2, follow these steps below to get your passwords into Firefox 3.5:

From Firefox 2 to Firefox 3.5 (upgrade):

1. Close Firefox 2
2. In the Firefox 2  profile folder locate and copy the files: signons2.txt and key3.db
3. In the Firefox 3.5 profile folder delete the files (note: not all files may be in the folder)

   • signons2.txt
   • signons3.txt
   • keys3.db
   • signons.sqlite
     

4. Replace (paste) with the files from step 2.
5. Start Firefox 3.5  Note: Firefox 3.5 will automatically generate a new signons.sqlite file

From Firefox 3 to Firefox 3.5 (upgrade):

1. Close Firefox 3
2. In the Firefox 3  profile folder locate and copy the files: signons3.txt and key3.db
3. In the Firefox 3.5 profile folder delete the files (note: not all files may be in the folder)

   • signons2.txt
   • signons3.txt
   • keys3.db
   • signons.sqlite
     

4. Replace (paste) with the files from step 2.
5. Start Firefox 3.5  Note: Firefox 3.5 will automatically generate a new signons.sqlite file
