Firefox on Android supports it without any issue. That would cover a significant enough segment of the population that it might encourage actual change in the industry if people started moving to that platform.
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.
