I use Chrome at work and Firefox on personal devices (including my Android phone).
As a heavy user of both browsers, as far as I can see there is really no downside to Firefox.
In fact, even though presumably there are way more engineers working on Chrome than on Firefox, I guess most of Chrome's engineering effort goes towards benefitting advertisers, not users. While Chrome seems entirely stagnant since I adopted it 4 years ago, Firefox gets a steady trickle of improvements and fixes.

So a huge +1 to the last point. Firefox rules.
