Using Tiscali BB with XP home and IE7 and Firefox browsers. Normally after clicking on the BB icon the dial-up box appears in IE7(the target) Recently I loaded 2 addons to Firefox to be able to access the Asus site. Now the Dial-up box no longer appears in IE7 but does in Firefox. IE7 is the default browser . Is it necessary to use the same addons for each browser?
