I have recently noticed that an application is slowly filling up my disk. Until today I was not sure of which application it was. I closed all my applications, some increasing disk usage others decrease but on closing firefox, a good chunk of space was reclaimed, about 50MB. That might not seem like a a lot but my drive is constantly full, teetering around the 100-200MB free range. So if any app were to leak space it could eventually cause my system to lock up until space is cleared.

Is there any way in firefox to monitor/debug disk writes to figure out which site is leaking disk space. It could also be a firefox bug but I think it is a site.
