First, congratulations for the good episode.

I would like to add two extensions that are very useful to be privacy and security aware while browsing and in the same time require almost no user intervention:
1) https://www.eff.org/privacybadger - this is a tool created by EFF (Electronic Frontier Fondation). It blocks spying ads and invisible trackers. The best part is that it learns which sites are trying to track you and automatically blocks them. You can always override/stop the block if you want;
2) https://addons.mozilla.org/en-US/firefox/addon/ssleuth/ - it ranks an established SSL/TLS (the one's with https in front) connection and gives a brief summary rating with all the details and a numeric rank from 0 to 10.

Another useful extention that is not privacy related is https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ - with it you can manage any SQLite database on your computer. For example Skype application have such  a file where the content of all conversions are stored.
