Adrià Mercader has just announced the first public release of WMS Inspector - an add-on for Firefox that allows a developer to view, and debug WMS (Web Map Services) requests and responses.

The main features are described as:

• Load all WMS requests in the current page and their parameters
• Requests sorting by service or type
• Individual WMS requests (images or errors) visualization
• Copy services, requests or parameters to the clipboard
• Direct edit of request parameter values
• Output GetCapabilities response as an HTML report or original file

It is noted that it will be especially useful when working with JavaScript map libraries such as OpenLayers and MapBender, or when setting up WMS Services; and I agree. This should be a useful utility when trying to match an OpenLayers client with a MapServer WMS server when non-default projections and map coordinates are in use.

WMS Inspector can be download from Mozilla here; and the announcement can be found on the OSGeo-Discuss listserver, here.
