For those looking for even more customized web content through Mozilla’s Firefox and aren’t afraid of installing a few plugins to do so, consider taking Greasemonkey for a spin.
This extension for the web browser allows the end-user to inject javascript into any viewed web page, allowing complete customization in any manner you wish. Since Greasemonkey allows the use of third-party scripts, a growing number of community-created Greasemonkey scripts are being made available. Some of the features in the user scripts include removing particular ads from individual sites to adding search boxes to others.
It’s an interesting idea and should make for some really useful scripts as time progresses.
