I actually find the new toolbar awesome
Irritating stuff for me:
1. Image blurring.
I'm sure it's leet and all that for teenagers who bought those awesomely awesome new graph cards and want everything blurry, but damn, this sucks for a retro player...
2. Password remember and auto-fill
After a fresh install and retyping all my passwords on all those boards/torrents/etc. they're not auto-typed, damn it!
In most cases they're just filled in the box and I have to click the logon button, but in worst cases, I have to start typing for it to fill and I'm lazy and used to just getting on the site and already being logged in!
