Not sure if there's a leak involved, or just result of the caching, but I see this in my about:memory

And note that in bug 692748, one user saw the nsLivemarkService.js compartment grow from 1,836,488 bytes to 20,847,464 bytes during 10 hours of idleness.

Bug 692748 comment 32 has the full analysis.

I must point my finger to the feedProcessor. But we also cache some objects (not that many).
It's quite good the issue is reproducible so we can actually test improvements.

Wontfixing because live bookmarks are going away - See Bug 1477667.
