Important privacy notice:

  • No cookie information besides the name and domain name are stored inside FlagCookies to work, no values, no direct details.
  • No session data or details are stored or processed
  • No history of visited domains or websites or any other tracking is used.

Before you use this addon: This add-on is mainly aimed at power users, this might sound harsh, but it is not!

To get the most out of FlagCookies, you have to define either own cookie rules for websites and or make use of Global Flag, or Auto flag, or Profile mode(s). Also, in case you use payment services, be advised to disable the "Global flag" feature temporarily. For example when using Paypal or other shopping/payment provider websites and services.

Long story made short - Basic usage:

  1. Use Global mode if you are surfing, this will remove all kind of cookies while browsing the web if not protected by profile mode, or explicitly are set as protected.

  2. Use Auto flag which will remove all cookies for one website/domain - this can be useful if you only want to automatically remove these page cookies every time you browse this website.

Hello Jan, I already tested your extension in the main browsers that I have installed on my laptop then I would like to give you some feedback. In google chrome, when you have the "Flag Cookies" extension turned on the browser's tabs starts to load really slow and if you try to type an url or something it feels laggy. About mozilla firefox, opera and microsoft edge all goes ok.

Very useful plugin. However, it has been slowing down my entire browser for the past few months. Anytime the plugin is active, websites like Google Maps become very sluggish and take long to load. This has to be addressed
