Firefox 96.0 system proxy exceptions problem
Big Problem in Version 96.0 with proxy settings. In Firefox the proxy setting "Use system proxy settings" is used. In Windows Internet Options the proxy is set and several proxy exceptions are defined with semikolons. Firefox only uses first proxy exception entry before the first semikolon. all other exceptions dont work. You can test this by deleting the first exception so that the previous second exception is now the first exception. Its always only the first exception in the list working. Going back to Version 95.0.2 - all exceptions are working again.
