About this Add-on
Note: Selenium IDE will NOT work on Firefox version 55 onwards. Please stay on Firefox version 54 or older. To keep yourself secure, install a separate older version of Firefox just for automated testing using portable Firefox or similar and install Selenium IDE there. Firefox will no longer support the core technologies that addons like Selenium IDE are based on. See https://blog.mozilla.org/addons/2016/11/23/add-ons-in-2017/ for more information. It is going to take a lot of time and hard work to make make Selenium IDE compatible and we are working hard on it. If you feel like it, tell Mozilla directly that you would like Firefox to support addons like Selenium IDE.
