swift key
When using the swift key keyboard in Firefox mobile, the period key, will delete the last character and enter a period instead of just entering a period. For example if you are attempting to type "example@gmail.com", it will instead type "example@gmai.com"

Thanks for the report. Other users have reported the same problem. We don't have a solution yet, but we'll work on fixing it. For details, see bug 602852.
Until we can fix this bug, you can use the Android "Settings" app to switch to a different keyboard.
