The title is bad, this only affects Firefox mobile that AFAIK has a really low amount of users (BTW, I am one of them).

Not saying that they shouldn't have detected this (i.e.: where is the automated testing for those things?), but I don't think this is Google screwing up Firefox on purpose.

And if Google really wanted to screw up Firefox, they would probably do a better job than User-Agent sniffing. Firefox already has an internal list where it applies fixes for websites (e.g.: setting a custom User-Agent), and the bug report actually comes from it. You can see it by going to `about:compat` page in Firefox.
