Even as a relatively new user of PM I totally agree with Moonchild and Tobin on this; Ever hear of reverse engineering? Take it apart (carefully)
see what makes it tick, then reassemble to working order or upgraded (hopefully) either hit or miss you will learn something about it.
There has been much info provided in this thread, Kudos to all that contributed, wonderful resources to look at for reference and help
I certainly will be making use of it when I can, as I have so far made 2 FF extensions (so far) PM compatible following the simple instructions
available on the forum, granted they were relatively simple extensions but I still have not worked out the licensing for them Yet
But I will
eventually (I just haven't seen any licensing info as yet in the folders/files I have looked at, but I have not looked at all of
And there are other files I want to get a better look at like some have js files, and I will tackle that when I can.
But the thing is, I can find all the info I need here in this thread and a few others on the forum, and there are always external sources
on the net that one can find if willing to search.
I would be further along in finishing the 2 extensions if I weren't so busy lately with family coming to visit me soon.
but after then I hope to have time to finish them and upload (with approval and correctly done) and announce, but only when ready.
I still have much to do but I know I can do it (given the time) and then once I feel I have become familiar enough with the code
(syntax/usage etc) I will do some others until I can make my own from scratch eventually (The Ideal)
But really anyone can do it given the desire, drive...and time
Edit: The ext's mentioned are not jetpack or other forbidden as far as I have seen, so far they both work as expected.
