Aha ! Images aren't stored anymore in the memory-cache (see bug 430061), that's why you don't see them anymore. But the cache is still there, it should be added to <about:cache> in bug 60305. Dupe ? see bug 454001 comment 1 for what the current memory-cache i used for.
Seems to be a duplicate of 454001, however I believe the old behavior to be better. Maybe limiting the browser.cache.memory.enable to something like 8192 or even 4096 would help mitigate the memory "leak" perception better than not caching images in RAM.
