February 8, 2016

Few months back Firefox team has made an exciting very big announcement to Firefox add-ons, they have brought a new extension API’s called WebExtension. This update has lot of exciting announcements for developers.

  1. Review process will become faster
  2. Development is easier, and the Addons will be compatible with Chrome and Opera.

The next step is to download the Firefox Browser and install them. You can either go for developer Edition or Nightly

Signature

  1. You can double click on it or else right click and select toggle. So it will be set to false

Why Web Extensions

One of the Main reason, to get started with Web Extensions is easier to develop. Previously I have tried developing some Chrome Extensions during my free time, so since the same thing is used here, it will be very easier for me to get started and develop well. So I write once for Firefox Addons and it will support multiple platforms.

Very excited for this new journey of learning.
