There are still issues with large cache sizes (512MB in my case), Firefox just stops adding new items to the disk cache after some time of working as it should. Most notably all new images show up as size: unknown (not cached) and it barely generates new files in the cache directory, even when visiting sites I know I haven't been visiting before.
With the planned increase on default cache sizes this should probably be looked in to beforehand, I can't give you a quick way to reproduce this state of the cache though as it takes roughly a week of my normal browsing activity to trigger it.

Maximum storage size: 	512000 KiB
Storage in use: 	345755 KiB

Cache directory as reported by Explorer:

333MB

Reproducible: Always

I encountered the same problem.

Here is my status:

Disk cache device
Number of entries: 	12330
Maximum storage size: 	716800 KiB
Storage in use: 	296698 KiB
Cache Directory: 	M:\firefox4\Profile\Cache
List Cache Entries

It doesn't increase any more thus all new images show up as size: unknown (not cached) like Simon.

Oh. I forgot to report my system.
OS: WinXP
Firefox 4.0b8

And It was updated directly from a firefox 3.6 profile if important.

Looks like the changes to b10 fixed this issue.
