I like Firefox. Still, it's a fact that Mozilla tends to have delays in releasing new versions of the popular browser. And now they're saying they're planning four major releases in a year? That's just insane!
If their efforts produce even one new version of Firefox in a year, I'd be happy enough. Unless those features they have in their plans are near completion already, it's more likely they'll have delays again and end up not doing the four releases this year.
It's just much too drastic a change from their current way of doing things.
