Here's where the update is Rated 5 out of 5 stars
Also thanks for the update now I can re-update firefox. I don't know if you'd want to but it would be nice to have a opera tab stacker extension that may be easier to keep updated and and is separate from tab utilities and is compilable with both tab utilities and tab mix plus.
