I’ve made Safari 4 Beta my primary browser. The new features are awesome and I love them all! If I had to choose my favorite, I’d pick the Nitro JS engine. It’s so much faster than anything else I’ve used. All of the new features are listed here.
The bad thing is, most of my old Safari add-ons no longer work. The good thing is, I don’t need ‘em. The search bar has auto-suggest which replaces Inquisitor. The only other feature I really missed was being able to open all links in a tab in the current window. Turns out that’s an easy fix. From the Terminal, copy and paste this code:
defaults write com.apple.Safari TargetedClicksCreateTabs -bool true
To go back the other way, just change true at the end to false.
More secrets specific to Safari 4 can be found here. Here is a link to the original as far as I’ve read (I’m a stickler for giving credit where it’s due).
Happy Surfing!
