When I click the scan button in the program I am using (WebPT) this error pops up in the program "Make sure you have selected "Install Missing Plugins..." from the yellow bar on the top of your screen in order to enable scanning if it is available. To manually install the plugin, click here. After the installation, please restart your browser." So I click "here" and Mozilla pops up a box in the corner stating "Firefox has prevented this site from asking you to install software on your computer". I click "allow" and it says "Firefox has prevented this site from installing an unverified add-on". I desperately need this add-on to do my job. PLEASE HELP!!
