Rated 4 out of 5 stars

I tested this add-on on the normal Firefox, works great, but since I switched to Firefox Developer Edition (v37, old Aurora channel) the add-on does not work anymore. Can you please take a look? I really think it is very important for developers to save their passwords in a safe place. Keep up the good work!

Later edit: well after I enabled debug, it seems it works, but on preferences page / security it does no longer say "your passwords are managed by an extension", but instead I can click on view passwords and he shows them in plain text without any master password or keychain password. Useless in this case, this is exactly what I wanted to avoid with this addon. Sharing password between browsers is nice, but not as important as protecting your passwords in my opinion.

This review is for a previous version of the add-on (1.1.8.1-signed.1-signed). 

I've just tested with 37.0a2 (2015-01-24) and it's working fine for me. (I had to reinstall the Addon though as Developer Edition now creates a new profile and thus does not have your extensions loaded at first)

If you're sure there's a problem, please enable debugging and file a bug report with the log output. Thanks.
