iOS’ webkit-only requirement, whatever else one might think of that rule, is the only reason anyone still cares about or builds for any browser engines other than Blink. The rule has (by accident) been more beneficial to Firefox than harmful, overall—it’s the single thing keeping more than one browser engine on the test list, even for smaller development shops and teams. [edit] nb this would not be the case if Firefox’s usage share were still large enough to “defend itself”, as it were. It’s purely due to circumstance.
