Good morning, I need to use an old version of Firefox to support debugging of an old program. I was trying to install the 24.0.3 version, which was working a few months ago on my old computer, but every time I try to charge a site it gets the message "'The connection was interrupted Connection to the server was restored during the download page. The site may temporarily be down or busy. Please try again in a moment. If you can not open any page at all, check your computer network connection. If your computer or network protected by a firewall or proxy, make sure that Firefox is permitted to connect to the web." I've already tried to delete my security software and to disable proxy, but anything works. How can I use such a version? Best regards, Serena
