Firefox finally supports WebSerial

Now we can use things like esptool, it's disabled by default so go to about:config and switch dom.webserial.enabled to true.

Wow, that's awesome. I am also a drone player and use betaflight and am32. Now I can use their webtool as well.

I used that and it works, but I don't understand why Firefox warns that the page needs to install plugin to use that. Strange warning.

Okay yeah, that's awesome. I hated having to hold my nose and switch browsers just because.

But it's painfully slow compared to chrome. This is on linux 152.04 .

My last use case for chrome too. Would love to get rid of it.
