The add-on downloaded from addons. mozilla. org could not be installed because Pale Moon does not support Web Extensions.
Is it worth requesting an add-on for Pale Moon, i. e. something not being Web Extensions? I. e., is it worth filing an RFE or it will be ignored anyway (I do understand that developers’ resources are not limitless)?
Or, maybe, someone can explain how to re-pack LT so that it can be installed in Pale Moon?
