Thanks Giuseppe for the firefox.js fix. It has corrected the tab errors and a few more problems for me. I noticed that the APP_NAME/APP_VERSION (like UA_NAME/UA_VERSION) line was not set, so took the liberty of fixing that. As I'm not too familiar with savannah or svn, I have uploaded my modified version to pastebin. Line 187.
