So the solution is to cripple your web experience by disabling interactivity and using a slower, more buggy browser? … how about stop making websites that are hostile to users?
Firefox has been far faster for me than chrome ever was (I have way too many tabs open that the same number would make chrome chug).
It is also an interesting take to have while defending a browser that is actively hostile to the user.
To see it on python.org I had to enable JS (using noscript) AND disable uBlock Origin.
> then Google went in to kill ublock origin. Ublock lite is nowhere near as good.
