I can't type some characters into firefox for android with physical keypad

Question

I am using an android device which is a Sharp 007sh that come with a physical 9 number keypad like those old nokia phone, running stock android 2.3 and using an input method modifier named as cedIME that can be downloaded from google play.
and with this setup, to type character into the phone, it is necessary to press multiple time a ley to get a character. For instance, to type a 'z' into the phone, you'll have to press the '9' button four time, so it change from w to x to y and finally z. However, in Firefox, when doing so to url bar and text area, pressing the first time the button '9' would create a highlighted character 'w', then another press would change the character from 'w' to 'x', but then it no longer being highlighted and the input cursor move to the right of it. As such, pressing the button '9' for the third time would not result in the intended change from 'x' to 'y', instead it would simply add a new character 'w' after the previous character 'x', and pressing the fourth time would thus result in another 'x', which make the output become 'xx', instead of the intended 'z' character. This problem is so far unseen on any other apps.

Hi Lilybri,
I still have this problem with the accents in AC and I've just found that problem comes from the double-type characters (like the accents in Spanish).

BTW, I got no answer from Adobe and i'ts been more than 2 months since I registered the bug...
Best regards!
