I made a small Firefox Extension for me and hope it's helping some of you aswell.
The Firefox extension WordPress Helper helps you working with WordPress by providing useful help and tools. The extension eases the fast and simple access to develop-relevant pages of the WordPress Codex. So you always have all the necessary help at your fingertips. It’s also possible to search after strings of text that is currently marked. Furthermore it’s possible to easily switch to WordPress backend of current site.
