I-Firefox ye-Android Isithangami Sokwesekwa

I am using a Samsung Epic with Froyo 2.2.1, and a Sony MW600 playing mp3s with "Just Playlists Plus". Everything works as it should until I open firefox. It seeps like Firefox is capturing the pause, skip, etc. commands from the headset and not passing them on to the OS.

When I fill in any field of text (including, but limited to the url bar, the search function and text things on websites), close them and then try to type something in it again or change something, it will copy the text I filled in or something. So if I type "test", close it and restart it again, it changes to "texttext" and I can't get rid of it, when I try it will just add the word again. This also happens in the url bar, if I try to get rid of the url. Is this a well-known problem for firefox mobile or am I the only one experiencing it? And, is there something I can do to change it?

Firefox for mobile successfully installs on my MID7022, running android 2.3.3 gingerbread. When I try to start the app, it shows firefox logo with black background and then crashes back to home screen. I have read the reqs on https://wiki.mozilla.org/Mobile/Platforms/Android and my device clearly meets the hardware and os reqs which can be read at http://www.cobyusa.com/?p=prod&prod_num_id=10576&pcat_id=1013
