Sorry, I can't switch to Firefox, as I've never not used Firefox.
I used it already when it was called Netscape. Before that I used Mosaic, which itself is not entirely stranger to Netscape creation.
Also, FF is not "a great alternative to Google Chrome". FF is a great browser in its own right. (Almost) always has been. And how could it be considered an alternative to anything when it was there first (or second, right after Mosaic)?
