Miniscripts от herronjo

Create or import scripts and bookmarklets to be run on any webpage at the push of a button. These scripts can be anything, from a simple bookmarklet that redirects you to another page, to a complicated script that manipulates the page in fun and interesting ways.

This extension was originally created by Madeline Kahn for Chromium based browsers and has simply been ported to Firefox. I do not own this addon and only published it to the Firefox Addons website with permission from the creator.
