hy there
since yesterday I have a problem with this scrip
all videos simply aren't buffering anymore (aka the white bar isn't going anywhere), they are just streaming

didn't change any settings or anything, it just stopped one day, works fine on IE and chrome (have the script only for firefox) or if I disable the script

Same problem here. Videos seem to be playing fine but there is no grey (or is it white?) bar that shows how much the video has loaded.

Same here.
