I'll wait for the experts to weigh in on this, but it's hard to keep trusting Mozilla when it buys an advertising company that claims -- contrary to essentially all available history of the genre -- to protect user privacy.
@rzeta0@dangillmor As an amateur browserengine dev I recommend webdevs avoid relying on JavaScript so its easier to develop alternative engines. Seemingly a tough sell...
Keep an eye on Dillo, Netsurf, LadyBird, & Servo. Or I'm developing my own. Or there's several commandline options!
But still keep Safari or Firefox (even if you don't like Mozilla's actions) on hand in case a site needs it!
