When I enter usernames in Firefox mobile (I have a Samsung Galaxy SII), spaces and hidden characters seem to automatically appear in the unsername as I type.

For example, if I tried to enter hefmoz as a username in the username box of any website requiring a username, I would get something like this: h e f m o z. Because of the extra spaces, the website would reject that name. I can back-space after each letter I enter and enter each letter a second time and that generally works. But, whoa! What a pain in the butt (finger, actually).

Thanks in advance for any info anyone might have about this.
