I'm having some problems too. YouTube just doesn't load for me, no
matter what network I'm connected to. It works under Epiphany and
Iceweasel but under Galeon (My main browser) it just doesn't load.
I've tried clearing cookies, cleaning the cache, but nothing works. I
haven't purged it yet because I customized Galeon a lot, but if anyone
thinks it would help I'd purge/reinstall.
