on my mobile, i keep safari's JS turned off and always in incognito mode. when i need to (like right now, to comment) i use DuckDuckGo app, which requires a fingerprint to open, for sites that require JS (like linkedin), or when i want to login.
At least use the NoScript plugin and opt-in to only the JS you need.
I ditched NoScript when I realised that it wasn't blocking inline JS. I landed on uBlock with Advanced Mode, which allows quick toggling of inline, 1st-3rd party and a few other things. uMatrix deserves an honourable mention also; it's been illuminating to see the sheer scale of trackers that are loaded on certain pages.
