I can no longer add an attachment to a post/reply using Firefox 8. When I try to click the button nothing happens at all (no pop up explorer window, etc). The last time it worked for me was on June 10, 2012. Since that time I have not updated Firefox or any addons, with the exception of the Flash plugin (to Flash 11.3.300.271). The only other change I can see I've made is to disable ad blocking software on this site. I can still add an attachment using IE 8, but please don't make me use IE!
Any help at all would be most appreciated ... Thank You!!
