Yes. I block JS on all sites in my default (general browsing) browser profile (separate firefox profiles for banking, shopping, etc.). Reader mode or viewing with CSS disabled (view -> page style -> no style) often reveal the content of sites that show a blank page or just "loading..." when JS is disabled. uBlock Origin element blocker gets rid of garbage occluding content too. To view sites that do not degrade gracefully, the Redirector extension is useful to rewrite urls. E.g., for twitter and reddit: (https?://)twitter.com(/.) -> $1nitter.net$2\?theme=Twitter (https?://)www(.reddit.com/.) -> $1i$2 Blocking JS is good for the environment :) A low-end machine can still provide a pleasant experience browsing the web. And, a more capable machine doesn't waste energy running useless scripts (also good for battery life). Disabling JS also substantially reduces attack surface.
