Hey look at that, Mozilla remembers they make a browser. After what we've seen from Mozilla the last few years it is genuinely surprising, but refreshing, to see a post like this.

@plexus but lots of their arguments for why they need their own browser engine are provably false. “Experiment with new user interface design”. Sure sure. Have you looked at Vivaldi, Zen, or Horse Browser? You don’t need an engine to do UI experiments 😅. Also, can Firefox please actually start to do real UI innovation again, please?

When you control the engine, you can fix problems or at the engine level and not work around them on the front end. When we create new UX, we also create in the engine things like accessibility and l10n support, or new web extension APIs to allow future addons to build on top of our new UX. Example with Split View that shipped yesterday:

BTW, Zen is a good Firefox fork, so it's based on Gecko 😃️
