Oh no you don't! Rated 1 out of 5 stars
The question really is a matter of integrity for Mozilla. If developers can remove ratings they don't like then how can we trust the system at all? Sooner or later people are going to figure out that just because the average rating says 4 or 5 stars the average add-on can't be that great. The entire rating system is untrustworthy as-is.
I have previously torn this add-on to shreds in my reviews over just how horrific it actually is. I see that they also have removed other negative reviews leaving an utterly false picture. IN NO WAY SHAPE OR FORM IS THIS WORTH 4 OR 5 STARS! IT IS A ONE-STAR CRASH AND BURN THAT SHOULD BE REMOVED FROM THE CATALOG!
Delete this and I will just come back and rewrite it.
