The biggest change here definitely concerns the Firefox version. The add-on for FF has been converted into a pure WebExtension. What does it mean and why it is so crucial will be explained below. Extension versions for other browsers hardly underwent any changes.
[Improved] FF add-on has been converted into a pure WebExtension #819
Mozilla plans to release Firefox 57 as a browser supporting only WebExtensions add-ons. So any add-on that is not a WebExtension will stop working. Due to this, Firefox Nightly had already been marking our add-on as a legacy one. This change guarantees that AdGuard extension will remain supported by FF-based browsers.
