User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20040914 Firefox/0.10 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20040914 Firefox/0.10 When trying to install an extension from update.mozilla.org, firefox reports that update.mozilla.org is the domain trying to install software, while in reality, ftp.mozilla.org in this case is the real domain. This will result in the plugin will not be installed, when only update.mozilla.org is in the 'allowed sites' list. When I added ftp.mozilla.org to the list, install dialog/window poped up and installation went fine. Please see attached screenshot about how Firefox detects the domain wrong about the site trying to install software/extensions. Reproducible: Always Steps to Reproduce: [got comment that this may be related to https, if you have visited a page with https before going to update.mozilla.org] 1. http://update.mozilla.org/extensions/moreinfo.php?id=10 2. Click on "Install now" Site will be blocked 3. Firefox reply that update.mozilla.org is blocked. Actual Results: If adding update.mozilla.org to allowed domains as firefox sugest, you are still unable to install the extension, because the real domain is ftp.mozilla.org Expected Results: Detecet ftp.mozilla.org as domain trying to install extension, instead of update.mozilla.org
