Sortable memory leak in FF 3.0.6

Since 2 days when my firefox updated to the latest version 3.0.6 I've noticed that the application wich I develop was very very slow, causing a memory leak in FF 3.0.6 when using sortables, the memory usage is increasing by tens of MB in just a few seconds while sorting a few elements, and the CPU is at 98%. I have tested also on IE6,IE7, Opera 9.6, FF 3.0.5, Chrome and my application behaves normally a.k.a very little or none memory increase and little CPU increase while sorting. It behaves the same using UI 1.6 rc6 or UI 1.6 rc5. You can see my code here: . Just search something, add the songs to the playlist using the "+" and then try to sort them (using FF 3.0.6) and you'll be able to see in task manager what I mean...

The bug reported by me seems to be present also in FF 3.0.5, still not affecting other browser vendors though...(FF<3.0.5 not tested)

This seems to be related to Firebug. With Firebug suspended, there's no excessive CPU load. Verified with original reporter. Thanks Andrew.

rather, there's an acceptable CPU load, but no memory leak with no Firebug or Firebug suspended.
