Even without this bug it's a stretch to think that Google would want to bury Firefox. Google has a vested interest in Firefox's success. That's why they pay Mozilla 300 million a year.
I'm not on the side of thinking Google are doing anything malicious here, but worth pointing out that their paying Firefox money doesn't mean they wouldn't neccesarily want to see Firefox die.
They pay that money not as a charitable donation but because the deal makes them more in advertising than it costs. From a monetary point of view, of course it would be better for them if all that advertising came from Chrome, so they still make the money but they don't have to pay $300m because they already own the browser.
