Configuring Mozilla Firefox to run actions

From Firefox version 57 onward, Mozilla Firefox only supports WebExtensions. Make sure you are running the latest version of Firefox and the latest version of the Lansweeper extension, which is a WebExtension. Installation instructions for the latest Lansweeper extension can be found below. Older Lansweeper plugins or extensions will be removed by Firefox when updating to Firefox version 57 or higher.
