On the Zend Developer Zone, there's a new post about two new browser plugins that have been created surrounding the popular Zend Framework, both related to research/searching.

Some enterprising Zend Framework contributors have hacked together a couple plugins for Mozilla Firefox and Internet Explorer. Ralf Eggert has created a sidebar to allow easy access to commonly used links, as well as a search module. From this idea, Richard Thomas was inspired to create a plugin to search the framework wiki and mailing list using Firefox's built-in search box.

The browser sidebar allows you to have the framework manual at your fingertips, and the search widget can grab information directly from the mailing list and framework's wiki pages to display in your browser.
