The X-Ray extension, which lets you see the underlying tag structure of a webpage, has been updated to version 0.8. X-Ray is now compatible with both Firefox and the new Flock Browser which recently moved into public beta.
The new version of X-Ray adds support for displaying tags for table, tr, script and a few other elements! Tags will now show both ID and Class details if they exist. The update also improves compatibility with the new Professor X Extension — also available for both Firefox and Flock.
