In the cache usage info I see such lines:
Memory cache device
Number of entries: 1817
Maximum storage size: 32768 KiB
Storage in use: 42248 KiB
Inactive storage: 0 KiB
Storage in use is bigger than Maximum storage size.
Reproducible: Didn't try
Steps to Reproduce:
Continuously web-surfing, and ~35 pages opened (every page is much smaller by 1 MB)

> Storage in use is bigger than Maximum storage size.
That's normal because it's not a hard limit. A single page can use more memory, for instance by using 50 images of 1 MB, which would be more than your 32MB. It happens sometimes when you use tabs, because each tab is consuming memory, and the total can be quite high.
Note that this is an *image* cache, it's not used for pages. And an image is much larger in memory than on disk too. A single page with a couple of images can easily consume 10 megabytes.
What probably happened here is that some of that memory got locked, and can't be removed from the cache again. That counts as a memory leak. But Firefox 3 will be a lot better in that regard.

If it's a soft limit, we shouldn't call it a "maximum" :)

This bug was originally reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.6 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
