Assegnate 5 su 5 stelle

Very good addons, i was need it many times, and not found it!
Only one problem (bug?) i once click to delete button and it delete two records in one time :(

Questa recensione riguarda una versione precedente (1.5.3) del componente aggiuntivo. 

You mean the Remove button in the Saved Passwords dialog? That's part of the built-in code, which I have not touched at all. I would suggest looking at bugzilla.mozilla.org to see if it has been reported, and if not, try to reproduce the bug (preferably on a separate profile with no vital data!) and submit a report.
