Great add-on Rated 5 out of 5 stars
I've used this Firefox add-on for years, and it has been super. I used it often to back up my passwords, not relying entirely on Firefox's synch function. I've used it to back up my passwords and to transfer them to new computers.
The only unreliable part is the encrypted version, which has failed upon importing. So, I save the unencrypted ones in an encrypted RAR file to keep them safe. If I remember correctly, it doesn't transfer the master password. You must go to the options->security and click for that in Firefox options and enter yours.
In any case, I've really used this a lot for years. Thanks for this add-on!
