> If you view GPL code with your browser would that mean that your browser now has to be GPL as well?

Some good responses in sibling comments already, but I don't see the narrow answer here, which is: No, because no distribution of the browser took place.

If you created a weird version of the browser in which a specific URL is hardcoded to show the GPL'd code instead of the result of an HTTP request, and you then distributed that browser to others, then I believe that yes, you'd have to do so under the GPL. (You might get away with it under fair use if the amount of GPL'd code is small, etc.)
