To our Tor Browser users: The latest Tor Browser update 12.0.3 made some changes that causes errors in Alby.
If you see an error: "(Could not establish connection. Receiving end does not exist.)" it means "Error: Please set webextensions.storage.sync.enabled to true in about:config"
So to work around this, go to "about:config" and search for "webextensions.storage.sync.enabled" and enable this.
we will look into ways to work around this new limitation.
