Disable on the page level
There is now a counter on the nav bar button that shows fired tags. Since I keep my GMail open the extensions seems to freeze the tab after couple of days because of lots of "catched" tags.
If I were able to disable tracking on the page level I could disable it on GMail while keeping it on other pages.
Our next minor release, later this week, will add this option to the toolbar popup.
This is more a bug than a feature request - we will address.
