If you've been in situation (from what ever reason) to develop code that offten crashed Firefox, making Firefox unresponsive, thus you had to kill firefox through "Task Manager" "Processes" window, you don't have to do it this way.
Firefox has "plugin-container" and it runs in separate process, so you can simple kill this process without killing firefox and this way preserving all opened firefox windows and tabs.
After that you just have to reload page with your "breaking-firefox-flash" and repeat this steps untill you fix the flash :D...
