STOP!!!!!!!!!!!!

I would request a stop button.
When we try to download filters.........
When we watch the filters in our FF...............
........many times the program continues to work on that filter even if we clicked another filter, even if we moved down to watch another filter, even we clicked to download another filter.
YESSSSSSSS, I know that, if we had a larger memory in our computer, it would not happen.
But you must think that not all people using FF are computer graphic professionals and that not all have a computer with a very big memory.
So........ what about a STOP button? If the filter spends too long to load, we just stop the execution and we load another filter. Is it possible?
