If you block certain domains then firefox becomes just as quick, but pictures and such are no longer clickable.
For youtube, get something to disable flash for it. Html5 is so much better it's not even funny, but youtube loves to default into flash. It's obvious which is currently being used when you right click in the video's frame. Try out "Flash Control" on firefox, or really any plugin that let's you control whether flash is on or not. Might help.
For general blocking of anything/everything, get ublock-origin and umatrix on both chrome and firefox and block to your heart's content.
