We’re going to have a serious problem on our hands soon with compatibility. I’m a software dev and I’m already seeing a few issues here and there where Chrome is being treated as the default expected browser and features don’t work on Firefox.

Firefox doesn’t support a fair few Chrome features because of security and privacy reasons, such as WebHID, WebUSB, etc.

Devs, please stop using those features. I know it’s tempting, but they’re basically bribes to encourage you to sell out to Google. Don’t do it.

Most “Chrome-only” web applications I have to use I can get around just by changing my user agent string and everything works fine. I try not to use that stuff when I can, though.
Some of the older stuff is indeed that way, but there are more and more features which Firefox can’t support. Web-based custom keyboard configuration tools, tools to flash phone firmware, and one niche MiniDisc tool all are chrome-only things I’ve had to open Chrome to use

tools to flash phone firmware

Yep. Forgot I had to use Chrome on Windows to flash GrapheneOS.

Wait is this real? That’s hilarious

Technically it works on Linux, but I didn’t feel like installing a Chromium browser to do it at the time.
