So flashed me a new ROM

Since then freezes the stock browser and Dolphin browser. Chrome works fine.
Hassle is I really prefer the stockbrowser.
 I've been told it won't be a ROM/kernal issue. Any one have any clues as to what it could be? or how I could try and figure out what it could be?

I don't want to go to the hassle of trying a different ROM as it taks a day to sort everything out after :(
