It's quite surprising to see how many JS plugins are in operation on a typical consumer site, and satisfying to know they were all blocked unless expressly permitted :)
For example, one particular maroon-headwear-related Linux distro's bug tracker has a particularly egregious blinking bright red banner, asking you to enable JS for the website to "function correctly", even though reading bugs on said tracker works fine without it.
Note that it is a hack/poc and does not always work, especially the x-frame-detection is iffy so if you try it and just see a blank page try the "enable proxy" checkbox. I use it every now and then on iOS to get around some especially obnoxious JS, but if there were more users I would be more motivated to improve it (hint hint:-)
