There is a company named Blackmagic Design who make DaVinci Resolve. To download DaVinci, you have to fill in a form with a loads of data including your name, phone and even physical address.
And guess what. The download button on the form just doesnt't work in Firefox. It's just ridiculous - Chrome-only download button.
I know it could be somehow connected to the browser settings like popup blocking or something. But the point is that I have nearly similar settings between all my browsers.
