This issue has been resolved in version 2.7.0 available at https://addons.mozilla.org/en-US/firefox/addon/sitelauncher/versions/?page=1#version-2.7.0
Currently this new version is "experimental" which is why it hasn't auto-updated yet, the auto-update will happen when Mozilla approves the update, but in the mean time, you can choose to manually install the update via the above link. Apologies for the disruption.
