Firefox 1.7 will not allow input from the scanner in the search field when running on the ET1

I have a customer requirement to use firefox 1.7 with their equipment maintenence program.

 

When I use the native browser I can scan information into the title bar or the search fields  on the web page when they are in"focus".. I did enable output via intent  in datawedge to enable scanning into the search bar

 

With Firefox, I can scan into the title bar but I can NOT scan into the search bar

 

Any ideas??
