[aur-general] Is dev.archlinux.org browser dependent?

[Stefan Husmann]

Hello TUs,

I finally managed to enter dev.archlinux.org to adopt some packages in [community].

I had to install opera to do so. I tried firefox, conkeror and midori, but all of them 
did not give me a login form but a message about an untrusted site. So my question is:
Are there any settings I have to apply (using about:config or the like)?

I would like to get rid of opera if I can. Hints?

Regards Stefan
