My browser is Firefox. A website I used to use has been updated and gives me a message that Linux is not yet supported when I try to login. I can use the website in a Windows virtual machine, but that is a pain because I need to switch back and forth between languages, and I don't have an easy way to do that in Windows. Is there some way that I can impersonate a Windows or Mac to use this site? I tried the addon useragent switcher; it didn't work at all.
