It really sucks for the honest developers, but as a result, I'm more comfortable using my browser to interact with dynamic content (like HN, Reddit, etc) while reserving local app installs to an extremely limited set of functions which need to operate on my local data where having both contact and networking permissions are a huge red flag.
This is all due to the interface though. Mozilla is a much more neutral party then Google. I'd rather untrusted third parties negotiate with Mozilla's API than Google's. What I'd like even more is good native software which treats users with dignity and respect, but those are few and far between on Android.
Sorry, but what "race to the bottom"? There are 1.5 millions apps in the iOS App Store. Inevitably a lot of them will be bad. But there are thousands of great apps at any price range.
