Firefox Browser not what it used to be?

Well at this point, I would have to wonder if Firefox has gone downhill? No offense to them, but code and embeds that work on Chrome, simply will not work on Firefox. It could be that the version is in need of an update, or it could be a problem specific to Linux, I don't know. But my recent experience has been that Chrome (with the possible exception of flash, which should be a technology on the way out, but isn't- which is another blog post) works far better than Firefox currently.
