It is the only active extension I have marked as "not designed for palemoon"
I did not know anything about Jetpack befote looking it up and even now I can't say to know it. I only note that I have two extensions whose xpi is named {id}@jetpack.xpi. One is for google-search-link-fix but does not contain the listed json. The other one is for IDCAC which has package.json but is not flagged as "not designed for palemoon" so I assume it will be OK (actually I currenlty have IDCAC disabled in favour of an IDCAC rule in ABL).New Tobin Paradigm in a specific not-for-discussion thread gave this rule and wrote wrote: ↑2021-04-06, 07:28Rule 3: Please attempt to find out if they are Jetpack (Add-ons SDK) by looking for package.json or harness-options.json in the XPI file and if they are then DO NOT LIST THEM.
Can someone enlighten me ? Just information, I am not requesting a solution or replacement.
