Rated 4 out of 5 stars

Since version 1.2.4 the highlighted phone number can now even be selected for copying to the clipboard.
More knowledge to better detect phone numbers and reduce false positives, would further improve this useful add-on for frequent callers. For example detect country (from host name) and apply country specific rules like available ranges (voippro.com download-able rate list has 30.054 routes in august 2011) and include minimum and maximum number length in the algorithm whether a number is a phone number or not..
