what are the different values for this preference "browser.cache.disk.capacity"?
on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.
so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

and in which unit is the default cache capacity size? mb or kb?
See:
# Disk cache capacity in kilobytes. It's used only when # browser.cache.disk.smart_size.enabled == false - name: browser.cache.disk.capacity type: RelaxedAtomicUint32 value: 256000 mirror: always

1. from when is this? when was it last updated? 2. you didn't answer my question properly with this copy pasted info.
You may deduct from the comment in the source code that setting browser.cache.disk.smart_size.enabled = true enables Firefox to automatically determine the size of the cache. There is no need to modify browser.cache.disk.capacity, merely flipping browser.cache.disk.smart_size.enabled is sufficient to enable/disable this feature.

and what about the ram? isn't there a smart size preference for the ram?
For the memory cache you need to modify the pref directly as you can see if you read the lines about browser.cache.memory.capacity right below the disk cache pref.
# -1 = determine dynamically, 0 = none, n = memory capacity in kilobytes. - name: browser.cache.memory.capacity type: RelaxedAtomicInt32 value: -1 mirror: always
so you're telling me that for the disk cache there are 2 preferences, a preference for the normal disk cache capacity(browser.cache.disk.capacity) and a preference for smart disk cache(browser.cache.disk.smart_size.enabled) to let firefox dynamically determine the disk cache size while the memory cache has both of them in one preferences like the line you provided does say?
You can see the effect of the settings by visiting about:cache in the address bar.
