Rated 4 out of 5 stars

This is a really nice addon for tracking packages - indeed, the best I have found. The only negative I can note is that there are frequent website pauses for up to a minute or more when you click track, which becomes rather frustrating. Support has been responsive to this on the two times I have complained, but it seems like the problem should not be happening as often as it does.
