Years ago I was on the "people who block JavaScript are crazy" bandwagon, until just loading a single news article online meant waiting for a dozen ads and autoplaying videos to load. I spent more time waiting for things to finish loading than I spent browsing the actual sites, which killed my battery life. I'd get a couple of hours of battery life with JS on, and with it off, I could work all day on a single charge. It was nice.
Ever since then, I've been using NoScript without a problem. I've spent all of maybe 5 minutes, cumulative over the course of several years, clicking a single button to add domains to the whitelist. If whitelisting isn't something you want to do, you can use NoScript's blacklist mode, too.
> I'm now so spoilt by the advantages of the non-JS world that I don't think I could ever return. I'm always acutely reminded of the fact whenever I use someone else's machine.
I relate with this 100%.
