I would like to know the same thing.

And I would also like to know why you're being downvoted.

Maybe somebody will reply instead of downvoting. That would be nice.

The decision to kill off Servo is looking less and less smart.

They ditched it. Probably was too useful, so decided allocate their resources to more useless projects. Go look at the Mozilla blog. They don't give a fuck about their browser.

I use Firefox, but the project is a sad train wreck.

And while we’re on the topic, even within C++, why isn’t Mozilla using better dev practices that avoid use-after-free bugs?
