I’ve been carrying on using Safari as my main browser for a few weeks now, and it hasn’t really annoyed me this time. The availability of AdBlock made quite a difference, of course.
But there was one little thing. It’s that muscle memory thing that I alluded to in my post about the Mail update. I’m used to pressing what I think of as the Backspace key (though Apple call it Delete) to go back a page when using a browser. Chrome understands this, Internet
Exploder Explorer understands this, and Safari used to. But apparently some people got upset because when intending to delete a character, they went back a page, presumably because they hadn’t bothered to check which field they were in, so the shortcut was removed. Instead, you’re supposed to press Cmd+[, which is fine, but slightly more effort, and my poor little brain tend not to remember it. I was irritated enough to do a bit of searching, and found a helpful solution in a few forums. You just need to run this from Terminal:
defaults write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2BackspaceKeyNavigationEnabled -bool YES
Restart Safari, and normal service is resumed. And if you decide you don’t like it, run the command again with NO instead of YES.
 For me, that is.
