Extension update: plan picker, free trial in the extension, real Fingerprint Shield

The next Chrome and Firefox extension update is built and on its way to the stores: - **Plan picker** inside the extension, so you can compare Free, Pro and Ultimate without leaving the browser. - **7-day free trial from the extension** for new customers, the same trial now offered on the website. - **A welcome page on install** with the first steps. - **The real AI Fingerprint Shield on Ultimate**: scrambles your canvas, WebGL and audio fingerprint so trackers can't follow you between sites. It still needs store review, so it is not live yet. We'll post in the changelog when it is available in the Chrome Web Store and Firefox Add-ons.
