Still no swipe to change tabs on iOS, which makes it a non-starter on that platform for me, and a browser I can't use on every device can't be my primary browser. Bummer, because I really want to use Firefox.
Is it really surprising that iOS isn't an important target for Firefox, given that Apple's draconian rules don't allow them to do much? If we're going to assign responsibility for this, I think Apple is who deserves (at least most of) it. Given the major (artificial) impediments imposed by the gatekeeper of the platform, were I in their shoes I would never invest scarce dollars into such a risky undertaking where there is a hostile* and extremely powerful overseer.
*To be clear, I mean hostile to 3rd party browsers, such as Firefox
