I just noticed this but maybe it's already posted...

anyway on Kong if you get an add-on for firefox called Flashblock it stops all flash items from playing, including the game from loading - but here's the good part: if you right-click select "Copy Flash Location" over the blocked game you can easily find where the save game file (.sol) is!

I'm not sure if it works for every game, but I just did it for the BoTD (Rebuild 2) and it's http://chat.kongregate.com/gamez/0012/5968/live/Rebuild2.swf?kongregate_game_version=1321581534(take out the kong game version and you got the location)

THere are other ways to do this but as I use flashblock I think this is one of the quickest I've used
