Display the X-Clacks-Overhead in Clacks Semaphore, including http-equiv meta tags. Forked from GNU_Terry_Pratchett
What is X-Clacks-Overhead?
X-Clacks-Overhead is a Firefox add-on that allows you to see and read the message included in the html header, as well as visually display it in semaphore style. It is a fork of the GNU_Terry_Pratchett extension and supports http-equiv meta tag detection.
This is a fork of the GNU_Terry_Pratchett extension, fixed to support http-equiv meta tag detection (as long as only one X-Clacks-Overhead meta tag is used). Thanks to IgnoredAmbience's review of the original extension for the required fix of changing "Document" to "document" in gnu.js.
In tribute to the late Sir Terry Pratchett many websites are adding the message "GNU Terry Pratchett" into the html header "X-Clacks-Overhead". This plugin allows you to see when a website is using the header and read the message included. The message is also displayed visually in the semaphore style from the upcoming board game "Clacks" by Backspindle Games.
