Mobile Air Mouse & Firefox: Any Way to Get an @ Symbol?

Anyone know a workaround to get an @ symbol and other symbols in Mobile Air Mouse? You can’t log into Web applications on Firefox in ATV using the Air Mouse app because of this deficiency.

There was a Mobile Air Mouse update released today that should address this issue.

Ensure Mobile Air Mouse is disabled through the Maintenance > Settings menu, then download the update through Maintenance > Install Extras.

I disabled the Mobile Air Mouse and tried to do the update but I am told that my Mobile Air Mouse is up to date. However, I still could nout get the @ symbol to work on Firefox. Please help!

The Mobile Air Mouse update didn’t resolve the problem. I’ve got MAM 2.0 on my iPhone, and the ATV update says I’m up to date. Any ideas?
