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?
