Recently I was trying with two new addons . SkipScreen and Screengrab which is similar to FireShot but something extra .

SkipScreen is used to skip the wait time . For eg : When we try to download some files from rapid share we may need to wait for 150 seconds . This wait time will be reduced when you are using the skip screen . This will skip the wait time not only of rapid share , but for the many sites . I hope this will be  a wonderful tool for you if you are using the skipscreen addon of Mozilla firefox .
