Does it depend on a binary or is it really a website requiring an operating system?

It doesn’t block you from using it but it claims that it will only function properly on Windows, MacOS, ChromeOS, iOS or Android. Which is complete bullshit. It actually didn’t work properly but I doubt that would change if I tried it in another platform, the website was so clunky anyway

I got it working now, had to change to flatpak Firefox, just the old version of firefox shipped with Debian slowing me down
