An efficient blocker. Easy on CPU and memory.
Protects your privacy by blocking spying ads and invisible trackers.
Protects you against tracking through "free", centralized, content delivery.
Prevent Facebook from tracking you around the web. The Facebook Container extension for Firefox helps you take control and isolate your web activity from Facebook.
- Firefox only: link.
Automatically switches thousands of sites from insecure "http" to secure "https". It will protect you against many forms of surveillance and account hijacking, and some forms of censorship.
Change your User-Agent string to a sensible-looking string which is different for every request.
- Change your default searchengine to DuckDuckGo or Qwant.
- Don't allow your browser to remember passwords or forms.
- Disable all kinds of autofill.
- Depending on your preference, don't allow the browser to remember any history.
- Firefox can be set to delete all cookies, history, etc, when you close the browser. Chrome can be set to forget all cookies (and thus logins) when you close the browser.
- Enable built-in tracking protection and 'Do Not Track' even though most sites don't honor the latter.
Third-party cookies - cookies that are set by another site than the one you are visiting - are basically useless, except for tracking.
Chrome:
- Settings - Advanced (bottom) - Content - Cookies.
- Enable "Block third-party cookies".
Firefox:
- Preferences - Privacy & Security.
- History - Set to 'Custom'.
- Set 'Accept third-party cookies' to 'Never'.
Firefox has a lot of config options that aren’t normally exposed to the user, all accessed via the url about:config
. When you go there, you’ll be warned that you might break Firefox. This is true, but not if you follow my instructions, so go ahead and click through.
Search for the setting privacy.firstparty.isolate
and go ahead and set it to true. This will segregate sites from each other much more strongly than usual, making tracking very hard.
