yes, but the default is google, and you have to go into the settings to make a choice, so most people keep the default. what i meant was the EU directive for microsoft where they actually had to put up a prompt at first use asking the user which browser they want, without allowing any default (and, i am not sure, maybe even a randomized list)

if the same was done for search engine choice for firefox then google would no longer be the default, and they would have no reason to pay firefox for that.
