I don't read the dumps but here are some things to try. Go to Adobe and find the uninstall/cleanup tool for Flash. Then uninstall Flash and the FF Flash plugin and run cleanup tool. Then reinstall flash it might also be a good idea to uninstall and reinstall FF after getting rid of Flash. Also make sure all of your drivers for chipset, video, sound etc are up to date form the manufacturer's sites. I don't know what AV you are using but AVG is frequently involved in BSODs.
