If you’re a fan of embedded metadata (and really who isn’t?), you might want to check out the latest release candidate of MozCC, version 2.3.9. MozCC 2.3.9 isn’t available from addons.mozilla.org yet; we’re just putting it out there for some testing. You can find the download link in the wiki. This version includes fixes for two problems recently reported:

• performance slow-downs when visiting pages with lots of metadata and
• problems with MozCC breaking other Firefox extensions (including Operator).

If you find bugs or have suggestions, you can report them by filing a bug or leaving a comment on this post. We hope to ship the final release (2.4.0) next week and make it available for automatic update for those of you who’ve installed from addons.mozilla.org.
