I need to setup a customized install of Firefox to run on a POS system. Theses are on a fully locked-down environment with all sites blocked except for specific URL's as needed. I need to be able to black the navigation bar address bar any popups and tabs. I want to be able to open the browser directly with a specfic URL that would be supplied in the call to the program(I got this part working already) But need to keep the browser fully locked down to prevent end use from doing anything other then clicking on links and filling out forms, and closing the browser. Any help would be truly appreciated.
