I need to complete an online interview, and the website on with can't access my webcam or microphone. I have downloaded the latest version of firefox and the latest version of adobe flash. when i click on the icon with the three horizontal lines, then i click on add-ons, then i go to plug-ins, and the third listing says shockwave flash. at the top of "shockwave flash" it says in red "shockwave is known to be vulnerable and should be updated." and then next to it, it says "update now" and even though i have already updated it, i click on the link, and it takes me to a page that says "blocked add-ons" and it explains why it's been blocked but won't tell me how to unblock it. please help.
