The irony of this is that when using Firefox to browse to /e/OS url to check for compatible devices:
https://e.foundation/installer/
I get a pop-up telling me that my browser is not compatible, and I should use Edge, Opera or Chrome. See [1]
I think it's due to the lack of WebUSB API support in Firefox, it is needed for the web installer, both for eOS and GrapheneOS
That's a bizarre one. 'You need Chrome' is bad enough, which even the bloody NHS are guilty of, but I always assume that's 'just' an assumption that not Chrome means IE or something, and they haven't woken up even to the proliferation of mobile Safari users.
When I clicked "Browse supported devices" it took me to https://doc.e.foundation/devices
