Firefox on Android has approximately 0.5% market share on mobile, less than Opera. I really doubt it's enough to spark any sort of industry-wide change.
If all Android users did this, something would change.
Google would make it harder to install Firefox? Like they are already doing with anything not on their approved list?
Firefox runs great 99.99% of the time. It’s easy to add extensions. So we should be pushing people to adopt it.
