1. My Kensington Slim Blade Mouse scroll ball works fine with Internet Explorer 8, but not at all, or partially, with Firefox V5.0. I don't want to update Firefox because your later versions don't work with my ZoneAlarm Forcefield browser security. 2. Your cor-el's response to my question posted at the link below was not an answer. I found a download for V5.0 at another site, but then as now I can't download anything with Firefox but have to use Internet Explorer to do that as well!! I was unable to make your "Submit Feedback" button work here (http://input.mozilla.com/en-US/feedback#sad) or in your suggestion box link below on that web page. When pasting the URL for this page, 'Firefox Made Me Sad,' into Internet Explorer, I got the message "Oh! So, you want to offer us feedback on Firefox. Thank you, but you'll need to be on the latest version. To do that, simply go to our download page and install/update to the latest version of Firefox!" Why didn't I get that message here in Firefox V5.0 if you weren't going to allow me to submit a problem report? I think that your attitude towards users with a problem with your product - STINKS!! Can You help me here, or do I need to DITCH FIREFOX ALLTOGETHER?? https://support.mozilla.com/en-US/questions/862968#answer-232481
