It's never been clear to me that Google is actively trying to take-out Firefox. Firefox's user base is pretty small - so if they succeed in reducing it they'd gain very little but lose some shielding from antitrust accusations.
I suspect that these problems are more to do with neglecting testing, and just not caring very much about non-Chromium browsers
