There are so many Firefox features that I love, and Mozilla is an awesome company that I want to support, but Safari and even Chrome are both still significantly faster than Quantum on my Mac.

Even with 50+ tabs open in Chrome, it still loads uncached pages 2-3 seconds faster than FF Quantum, with fewer flashes of unstyled content as well.

I had high hopes for this refactor, but it looks like I'll have to wait to switch browsers until the speed really beats Chrome.
