With some of the whinging on this page, one might think some of you have actually paid for this software, as you do with Chrome ("if you're not paying, you're the product.." {yes, I know FF is essentialyl free if you don't donate to Mozilla, but it is funded, so a bit of a different beast).
After a month or so on Chrome (and its playmobil interface) not long after its initial release I came back to Firefox and have stuck with it ever since, because it does the job and isn't Google or Microsoft with whatever telemetry known or unknown they've secreted within.
That latter point's really important to me.
