For starters, since I am on LibreWolf, I have WebGL disabled, meaning that my browser does not support slow, performance-tanking 3D renders, at the cost of breaking them. Now, this is just a positive side-effect as an effort to disable WebGL fingerprinting - if the website is broken, I don't even bother using them.
I want to stop supporting websites that are performance-heavy and unnecessarily bloated, so that I can show solidarity with folks who are unbeknownst victims to the digital divide, and discourage enshittification of the internet. Any websites that helps with this?
You can kinda sorta use user-agent switcher as a proxy, if site tells your "10 year old" firefox to fuck off, likely it does some of that stuff (although its mainly google docs and other interactive ones, heavy media sites still work as i checked now:(
