I've switched to Firefox over the last few weeks. It definitely feels faster on my desktop PC which runs Linux, also no problem in Windows when dual-booted.

Though there are two big issues imo:

- When running Firefox on my late 2013 Macbook Pro, it doesn't feel as fast as Chrome or Safari, it feels very sluggish. I am forced to use h264ify to force YouTube to use h264 instead of VP8/9 as it makes my Macbook Pro turn into a steam engine. Besides the fact that this is Google's fault and its "monopoly?", it all around just feels slower elsewhere as well and it takes more power compared to even Chrome it seems to me.

- Lastly it does not sync all of my settings that I want. Why does it not do that? I run Firefox on Linux, MacOS, and Windows and I have to change my settings everywhere every time I make a change and it's a pita. Google Chrome just syncs all of my settings across all of my devices except for extension settings (which is a bummer).
