Rated 4 out of 5 stars

Easy to use, unobtrusive, easy to turn off. One shortcoming: does not recognize phone numbers that don't "look" like phone numbers. A problem for me as a site I use often lists 10 digits with no dashes, spaces, or parentheses. Would love to see this ability added.

This review is for a previous version of the add-on (1.2.6.1-signed).
