Hi, When using Firefox on an Asus Transformer TF101 running Android 4.2 the browser will often stop scrolling up or down, and becomes mostly unresposive. You can still tap the address bar and cut/paste there, but you can't open any bookmark. Closing the browser temporarily solves the problem but it always comes back at some point. This doesn't happen with other browsers including Chrome. This started happening maybe two or three updates ago. Any ideas on how I can fix this?
