This change breaks firefox on my system. I've noticed that some pages
doesn't load correctly anymore (e.g. facebook, spiegel.de). The pages
start loading and than stop. Looks like firefox is waiting for some
dynamic loading content. I've bisected to this commit, but can't revert
because of conflicts.
