it's just a blank page. how do i access about:config?

while i'm here i'll take the opportunity to say how much i hate the new firefox. it was perfectly fine the way it was. the old firefox doesn't work now but ignoring that it was an excellent browser. now look at what they've done to it. never mind the privacy stuff. everything's all hidden away under multiple clicks, stuff you used to be able to do in a click now has to be done manually. why have they done all this? who is it benefitting? it's not even faster like they're advertising it as. i only finally installed this because the old one's finally kicked it. i want the old one back. where are all the add ons? one i used to use that was totally indispensible doesn't work on this one. and where's about:config?
