I have no problems in browser, email or gmail.
I wiped cache, dalvik, did superwipe & fix permissions. Guess if you are having problems with any of these then it's something left over from previous rom somewhere....(didnt change any other settings such as gpl etc)
The rom itself is liquid smooth, noticeably slicker than any of the sense ics roms. Easily top of my list as a daily driver now.
Also syncs all my contacts properly which the sense ones weren't doing...
Just did the exact same steps, super wiping, wiping cache and dalvik and then installing and afterwards fixing permissions. Still same problem with Gmail
