does Google severly dislike Firefox??

with the recent news about the things that were said about Google slowing down Firefox on purpose, are they doing this because they severily dislike Firefox/open source? :c If so, that wouldn't make a lot of sense!!! Because Google loves open source too. I read they were doing this to stop adblockers, and well if you use Firefox without those, it can work maybe! I use Chromium and Google Chrome on Ubuntu ^u^
