"To demonstrate, here's a URL split across three lines.
"Note that it's just text, not a link:
http://maps.google.com/?ie=UTF8&om=1&t=h&
ll=45.123694,-123.113834&geocode=&q=&spn=0.
004474,0.010976&z=17
"What do you do with something like that? You can play a game of
"pin the tail on the URL", painstakingly assembling the long line
piece by piece in the URLbar. Don't accidentally add any spaces!
But in Firefox you don't need to do anything of the sort."
