If you want to keep this addon but dont want to use an outdated version of ff then install "firefox esr" and use the firefox profile manager to create a profile for the ff esr and one for the reg ff or quantum and install ff esr in a differnt location than the defualt location so you dont over write the default firefox and make sure you link the orig ff icon and profile to the reg ff and the ff esr to the ff.exe location and the profile i norm use linux where i can actually run multiple versions of ff at the same time but on windows it only allows u to run one version at a time just make sur ethat when u install ff esr to turn off auto ugrade so that u can keep the version that works with this add and u will still get all the security updates
