Firefox 4 caches

I downloaded FireFox and installed. My question is, should use both browser.cache.disk.enable and browser.cache.memory.enable ?? or just memory? because i know the memory will wipe out after shutdown.

I have been using memory only for a long time 3.x and continued with same in FF4. I never had an issue. I like using memory, it is faster and cleans up when done.

Default on my machine was 32MB(about:cache). But since you brought it up, I increased it to 128MB, by adding the browser.cache.memory.capacity 128000 variable.

I'll try memory only and check what happen.

I enabled memory cache only but it doesn't matter if i put a higher number to use it stick with 32MB of cache. Anyway to bypass this?

Check for typos. One letter wrong creating the new integer: "browser.cache.memory.capacity"and it won't get picked up.
