I use Firefox everywhere, but there are a few main issues that stop me from converting people...
- The lack of tab groups. This seems silly, but most people I know, especially on mobile, keep a lot of tabs open. If they're researching something, or shopping for something they'll leave 20 tabs open. Having that in one tab group in Chrome is a better way to organize than just tons of tabs.
- Sites that don't work well on Firefox. Again, specifically on mobile I run into sites that work on Chrome but not on Firefox.
- General stability issues. I need to force close Firefox once or twice a day because it will just fail to load pages.
Without even knowing where those roads are I see you are on the West Coast.
