Is there a webkit compatibility mode to make Firefox try to listen to -webkit css flags?

Firefox Web compatibility

Or is the only option - as a web developer, to make duplicate css flags?

I.e: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-webkit-slider-runnable-track & https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-webkit-slider-thumb Where firefox supports the behavior, but under different flag names https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-moz-range-thumb & https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-moz-range-track

Im also looking for recommendations on barebones/simple parsers that can help make my html/css/js more compatible without messing up the code too much. Im hoping to avoid having to use a build system.

Thank you

There's no webkit compatibility mode, as Firefox understands majority of webkit flags by default. But we didn't implement any of this two yet. Standardized ::slider-* is being tested under the layout.css.modern-range-pseudos.enabled flag, but we want to support ::-webkit-slider-* as well.

So for now you have to use both, but in a few months you'll be able to switch to ::slider-*
