If they are really displeased with Google, and I'm sure they are, they should run a campaign to invite users of their sites to install a browser different than Chrome. If they manage to destroy Google's quasi monopoly on the browser they'll make Google less powerful overall.
Maybe developers could stop designing websites that only work on Chrome too? I'm tired of seeing "your browser is unsupported" and denied access while using a chromium based alternative. Or broken features because someone had to have their bells and whistles
Like it or not, at least Google blazes ahead and brings new features to the browser sphere. It's not like innovation can be expected from Firefox any more, not with them cutting costs on the development team.
