Between Firefox 3 and 2 there is a difference in processing <?xml-stylesheet ?> in an overlay file.

ie, if <?xml-stylesheet?> is before <overlay> tag it is processed.
if it is inside <overlay> tag it is not processed by Firefox 3, 
for Firefox 2 that is also processed.

2. goto about:config
3. set extensions.checkCompatibility and extensions.disabledObsolete as false
4. install attached clickspeak_bundle_v1.2_release_orig.xpi

This was an intentional change from bug 319654. See also bug 360119. You need to fix your overlay.
