And it cannot be stressed enough how important that is. We don't want a repeat of the Internet Explorer fiasco which arguably held the Internet back for a decade because its market share was so big that nobody could compete with it and therefore Microsoft de facto controlled the web, without any real competition, which meant there was less market incentive for them to do a good job.
And I'm not saying that to rip on Microsoft either, it always end badly when one organization has that much control, it would have been the same with Google or Mozilla I'm sure. So no matter which browser you like, be it Microsoft Edge, Mozilla Firefox or Google Chrome, wish the other two good luck, it'll be better for you as a user in the long run.
