I suggest you to remove trafficlight because BD already covers everything. BD just does the same thing
and according to my test, BD trafficlight consumes resource and noticeably slows down your browser speed especially firefox
you can live without web filter extension
if you are paranoid and want an extension, I recommend avira browser safety
Avira Browser Safety - Free security add-on with anti tracking
after installation, go to its settings and uncheck all options
