Mozilla Firefox 3 hits. My grandma uses it.

I am so posting this in Mozilla Firefox 3 right now. And I’m pretty happy about that.

Sure, Opera rolled along a few years ago and made the point that a decent product could put a slight dent in Microsoft Internet Explorer’s market share.

But things lit up a bit yesterday with news that Firefox now has a whopping 19% market share.

A lot of people I know have used Firefox for a while. But that’s just demographics. Everybody I know is voting for Obama, too – I’m 20-something in Massachusetts here, after all.

Nineteen percent, though? Is my grandma using Firefox?

I’ve just downloaded this (note to my IT guys: That’s cool, right?). So there hasn’t been much time to get a feel for performance and new features. The Mozilla folks have put together this handy little guide, though.

From a consumer perspective, this thing still won’t run Netflix instant watch movies. Maybe that’s Netflix’s call? You might want to check if it works with any SaaS applications before conducting a large-scale deployment.

Then again, facing a 19% market share, maybe the people selling SaaS applications should be checking in with Firefox.
