Just tried Firefox when logged out (so all the adverts) and clicked around for a while. I didn't get any file downloads. I'm on Windows.I've noticed something lately when browsing the forum using my normal Firefox browsers. This happens on Windows, macOS and Linux. I keep getting files downloaded, and they have seemingly randomly generated names like fPoEyEhh.html and are 0 bytes. It seems to happen randomly just clicking on links. I can't so far establish any pattern.
