Sometimes I'm using Firefox for playing music from my own ftp. And when I close the tab with played track or just return to the page with list of all files in directory, firefox starting to use 1 thread of my CPU. If I close window, Firefox process is usually exist and still use one full thread (25% of 4-thread CPU).

Please, fix this

Check if the cache is fullfilled. Is this also happening after clearing the cache?

If so, please file a bug on https://bugzilla.mozilla.org/enter_bug.cgi (and provide here a bug number to let us follow it).
