firefox worked fine with beta4, but after update to beta5 the passwords stored in firefox behave strange:

for login at bugzilla.novell.com I did store user/password. now with beta5 the login page does not insert/show my user name anymore in your bugzilla login page.

when I click into the username input field I get a selection list of user names with the correct user name for that page, but showing multiple user names for at least one other web site!  

I tried to check the saved passwords in firefox via Edit -> Security -> Saved Passwords...   but this window shows _no_ site/username entries at all :-(((


what's going on here ?
