Hello. I'm on Windows 8.1 and I just installed the latest Firefox version and I wanted to install Firebug and Stylish extensions. But now it says: "There was an error downloading Stylish. Try again". The same versions of extensions and Firefox works fine on Windows 7.0. Can you help me to understand the issue please?
