I really like using PWA's but FF does not allow them. I have seen a PWA extension but it requires a whole bunch of Software be added to achieve it.

Is there any other solution without resorting to a Chromium based browser ?

I have been seeing a lot of Double Postings showing up in Threads from the Same sources. These are definitely not CrossPosts. They are in the Same Magazines, so I am assuming that they are either being fed in Double to this instance, or the Database has duped them for some reason.

Can anyone confirm this ?!
