Hi, I have a problem trying to sign a document with a certificate. I had imported it when I was using Firefox 3.6 and it used to work ok to identify myself to log in to some site. However, I never tried to sign a document with that certificate. (I work with a Mac, in case that is relevant.) I recently uploaded to Firefox 4, and now I try to sign a document. Ok, so Firefox asks me for my master password. I had not set one (or I can't remember), so what I did is to "reset" the master password. Now, I try to set a new master password: I fill in the fields, click "Accept"... but it doesn't do anything, so the master password can't be set. Also, if I try to import a certificate (which was removed when I reset the master password), I can choose the file and choose a password for it, but again when I click "Accept" the password is not set: simply nothing happens. Has anyone else had these problems? Is it a Firefox4 issue or did it also happen before? How can I solve it? Thanks in advance! jordimp
