The third column is your current browser and platform, and for me it's showing Firefox on macOS missing a lot of features. When I switch over to Brave, I see Chrome on macOS. Interestingly, Chrome on macOS apparently supports vibration, despite the hardware for it being nonexistent.

While true, that does not seem to align with what the checkboxes for firefox, looking at many of the ones that Safari does not support other non chromium browsers don't support on any OS. Mobile or not
