I've installed the Android version of Firefox on my wife's Chromebook via the Google Play store. There's also a way to enable Linux within ChromeOS and install the more full fledged version of FF.
Potentially related, not sure: does anyone know how I can get touchscreen scrolling working in Firefox on a fresh Ubuntu 23.10 install? Currently it's just selecting text and it's driving me up the proverbial wall. Googling was unsuccessful.
I disagree. This is yet another bad headline in a string of bad headlines that I'm certain won't make advertisers go "ah yes, let's up our Twitter advertising budget".
There's this: https://github.com/iBicha/playlet
But I haven't quite figured out how to use it yet.
