Gosh, I don't know where to put this request, so I'll start here, and you guys can send me to where it should go, even if it's off this site completely. So...here goes nothing:
The ONE single thing that keeps me from upgrading to the newest Firefox versions is that my absolute favorite add-on has lost its developer. That is the add-on called Cards, which includes among other things, free-cell. The reason that I liked this add-on so much is that in the portable version I could play it at work where free-cell was not installed on our computers (yeah, I know it's wrong to play it, but what are you going to do while you're on hold, or waiting for an application to crunch out a result, or while you're on a boring conference call, etc.). It also allowed me to play free-cell on a Mac. Besides, that, I just liked how the game functioned better than the Microsoft Windows one.
So, my question is, how can I get the actual game extracted out of the extension? (I have the Cards .jar file and the .xpi file, and for a while I toyed with the idea of trying to do this myself, but I simply don't know where to start.) Ideally, I'd like to get the game to be an add-on to the new version of Firefox, but I don't know that this is a fair request to make here, so I'd settle for just getting the game as a stand-alone application which doesn't rely on being installed (so it can be played from a jump drive).
I'm a real addict to this little game and in the spirit of this site, I'd gladly make a sizable donation here -- Hey! I'm not above incentivizing this effort!
Plus, I'd like to be able to move on to the latest version of Firefox.
If there is already such an application out in the wild, I would love to know about it -- although I've looked around and haven't been able to find one that fits the bill. If this is the wrong sort of request to make here, then can someone point me in the right direction or give me some tips on how I might go about getting this done myself.
Thanks for everybody's patience in reading this.
