But Greasemonkey has changed all that.
Greasemonkey is a free extension (available at http://www.greasespot.net/)
for the Firefox web browser that lets you add custom JavaScript code to any
web page. The code then runs automatically as though it were part of the
page itself and alters its appearance or changes its behavior accordingly.
There??™s also a version for SeaMonkey at http://xsidebar.
mozdev.org/modifiedmisc.html. If you??™re using Internet
Explorer, try Trixie (http://www.bhelpuri.net/Trixie), which
runs Greasemonkey user scripts on IE. Keep in mind that
most Greasemonkey user scripts are written for??”and tested
with??”Greasemonkey on Firefox, so there??™s no guarantee
that they??™ll work as well (or at all) with Trixie and IE.

By itself, Greasemonkey doesn??™t do much. To bring it to life, you must
install user scripts that you download or write yourself. Most user scripts are
designed to add features to individual web sites, but some are written to fix
bugs. Visit http://userscripts.org/, and you??™ll find enough gems to keep you
entertained for some time.
The easiest way to find a user script is to search userscripts.org for the site
you want to grease up. For instance, there were 35 scripts for Google Maps
at the time of this writing, including one that changes the input field to a
multiline textbox, making it easier to copy and paste street addresses, and
another that lets you quickly zoom to a specific region on the map by drawing
a rectangle right on the page.
