No thanks. I'll accept it in my browser when they fix the security implications this raises, and when the Spec is no longer in draft.
What are the security implications this raises that downloading native programs (needed for example to flash my smartphone) doesn't raise?
And I'll just fire up a chrome instance which I specifically keep for when my daily driver firefox decides to spazz out and not implement basics in 2026 :'(
The security implications of not having WebUSB are having to install untrustworthy native drivers every time you want to interface with a USB device.
