  • Supports manual mode cleaning from the popup
  • Easily see the number of cookies for a site

Contributing code

  • Bash (cause there's some .sh scripts, otherwise you can't do npm run build, but can still do npm run dev)
  • Latest version of Node.js
  • npm install - Installs all dependencies
  • npm run dev - This will run the webpack watcher and automatically pack /src/background.js and its dependencies to /extension
  • npm run lint - Runs the eslinter for JS files
  • npm test - Runs the test suite located in /test
  • npm run build - Builds the Firefox (.xpi) and Chrome (.zip) builds
  1. Run npm install (if you haven't already)
  2. Run npm run dev
  3. Load the extension in the browser
  • Firefox

    • Easiest way would be to run the tool web-ext
    • Another way is go into about:debugging and load /extension/manifest.json
  • Chrome

    • In the extension tab, enable Developer Mode, then load unpacked extension and load the /extension folder
  1. Run npm install (if you haven't already)
  2. Run npm run build
  3. The build files should be in a new folder called /builds

What's wrong with Mozilla ? How many months (it's a big late) ?

If you're wondering : WebExtensions doesn't have one feature(s) ? Now I got one answer.

In fact, it's too soon to migrate (or replace my addons) to Firefox Quantum (aka Firefox_v57 which was published in november). Because the WebExtensions seem's to be limited (or not yet ready).

That's true Cookie AutoDelete_v2.1.0 is a good example. Because yes I had try again today (the both : white and grey list). And despite my attempts, the list (called cookies exceptions) wasn't modify (it will remain empty).

The list could me modify with an addon like Cookie Keeper. But (for now) it can't be done with Cookie AutoDelete (as reminder it's a WebExtension) and that's just bad.

While initially not so much interested, Mozilla now is making more APIs these days which allow addon makers more control over the browser.
