Rated 5 out of 5 stars

Very very good add-on, I'm using it for years.

The only missing feature is to be able to increase the message count limit and/or allow to totally disable content messages (not only filter them). I'm testing my addons on websites that fire a lot of warnings and errors, and sometimes the chrome messages disappear because the messages count reach the maximum.

This review is for a previous version of the add-on (0.6.1).
