Reproducible: Always Steps to Reproduce: clear your cache the old fashioned way be deleting all the files from the profile folder: now, in the gui, tools > options > advanced > networks > offline storage > enter a really big number here like 2000 mb. surf to http://favicoop.com/ to fill up the cache object entries, keep surfing until the about:cache tells you that you've got 8192 items in the cache, or as close as it will go. now visit another site which is normally cachable, but isn't currently cached. right click an image, select properties and note how firefox hasn't cached it Actual Results: Caching will stop Expected Results: an object should be evicted from the cache to make way for new content.

Mark, you set bug report = version 3. did this work differently for you in version 2?

dupe to bug 524232?
