In 2001, I published a paper about something I called "Active Browsing":

...In active browsing, the client browser actively modifies content before display. Instead of accepting web pages "as is", active browsers transparently modify, delete and edit web pages according to specific user needs.
but it wasn't until I saw extensions like Greasemonkey, Aardvark, and Web Developer that I saw how Firefox and Mozilla's technologies supported user mediation in a transparent and useful way.

Platypus is a Firefox extension which lets you modify a Web page from your browser -- "What You See Is What You Get" -- and then save those changes as a Greasemonkey script so that they'll be repeated the next time you visit the page. Editing pages to suit your needs is dandy -- but making those changes "permanent" is the real payoff.

Some of the things you can do with Platypus include:

Of course, web pages change all the time, so Platypus doesn't work well on some pages, and your Platypus script might break if a web site changes its format. And some times your changes will break a web page in unexpected ways. But you can always undo your changes by reloading the web page, and if a script breaks, just delete it and create a new one. So play around and enjoy yourself!

To get started:

  1. Install Platypus.

    Note: To save changes and apply them the next time the page is loaded, Platypus requires Greasemonkey 0.3.3 or higher to be installed.
  2. Learn to use Platypus.

If you use Platypus, please suggest improvements and report bugs. Common questions or problems might be addressed in the FAQ. Thanks! Special thanks is due to the members of the Greasemonkey mailing list, who provided valuable help and insight in developing this extension.

Extras

Example of source displayed by VRSView Rendered Source is a Firefox extension that display color-coded, formatted and styled HTML source.   It's a big improvement over Firefox's normal source viewer.  Jennifer Madden has graciously modified VRS to work with Platypus, so if you install View Rendered Source, Platypus (0.51+) will automatically make use of it when displaying source (the "View Source" command).  Install it now and check it out!
