Gentoo Firefox phones home

Some while ago, I submitted a bug to the Gentoo Bug-trac. I had trouble with Firefox when switching from non-proxy to a proxy-network.

I found that when starting firefox (note: not firefox-bin) the proces wants to connect to :-(

Now someone found the issue:

I have the same problem with mozilla-firefox-
Firefox tries to connect to the page mentioned in
pref("browser.startup.homepage", "");
If DNS or the page itself is unreachable firefox waits until the request

I haven't test it yet... but it might solve the issue... ;-)
