Isn't the Firefox browser, and through it the search engine traffic which they sell the rights to, the thing that keeps their company running?

You'd think they'd be focused on making a better browser, clawing more market share, and cementing their presence in the browser space.

I used to use Firefox almost exclusively, but lately Chrome and Safari have filled that need. Breaking compatibility with old plug-ins might have been necessary, but it made switching a no-brainer.
