Are you able to update to the new Firefox 14? (ie. on a supported phone, not a tablet ATM).

I am set up for automatic updates, and have the current version on my smart phone. But there has never been a problem with the phone. This is specifically about the tablet. What is the connection?

I downloaded version 14 to the tablet (no problems), but the keyboard was unchanged: still no colon. I suspect it may be something specific to the hardware (it's a Kocaso tablet).

Duuh. There are several options selected by the tab key. Problem solved.
