Hi,

When viewing motion jpeg streams (from axis network cameras for eg, but happens with all mjpeg streams), the mjeg stream download is not terminated when the tab containing the mjpeg image stream is closed.
This seems to be a firefox bug, and has been present for a number of years across all architectures.

This also seems to lead to a memory leak eventually, if firefox is left
on in the state of having closed one of these tabs but the stream still
being received, then it will eventually use all available memory,
resulting in system slowdown, or crash.

This is always reproducible.
