On the GeoServer developer list we’ve been discussing reducing browser support in the GeoServer web administration console - browser-based clients using OpenLayers and other JavaScript mapping libraries would be unaffected but the admin console would have support for fewer browsers.  Please help inform this decision by letting us know which browsers you are using to configure GeoServer at this web form:

We’ll review the results in one week. Thanks!
