I asked this on Stack Overflow and it was suggested that I ask here instead.
I have tried searching for this but nothing I find quite matches my issue. My wife and I run identical setups. We both run current XUbuntu and Firefox. We always apply the latest fixes so we are always at the same level. My setup works fine. On hers it constantly asks for a login and password on sites using HTTP authentication. It remembers her credentials just fine so all she has to do is click OK but as you can probably understand, this can get quite tedious.
I tried wiping her mozilla director and starting fresh only loading her bookmarks. I recently set her up on a new laptop. It's actually my old laptop which was working just fine for me. All I did was copy over her home directory.
As far as I can see, it is something in her specific setup from her own home directory. Can anyone shed some light?
