I've been using NoScript with block-all by default (on a laptop - not mobile) for about two years now and I really appreciate how many sites I can visit and immediately close due to the sheer number of scripts that would be require enabling to actually render the page.

It's a nice way to screen for better browsing experience pages.

Try Naked Browser (http://nakedbrowser.com/android/ or Play Store link https://play.google.com/store/apps/details?id=com.fevdev.nak...)

Despite the somewhat contentious name the naked refers to it being stripped down.

Once you get the hang of navigation it is extremely fast and a simple long press enables JS (if a site really needs it).

firefox on android supports noscript

I use Firefox Android uTorrent's manual Javascript toggle (under "More"). I've found NoScript to be too much work but an easily accessible manual toggle works for me.

That same Vivaldi does have a JS toggle.
