Cache policy of firefox on android
Please add an option to choose the device used to store cache, history... Actually, ff use and saturate phone internal memory, which is very limited, instead of internal or external sd card.

There is no feature or add on that I know of that does this yet. However the one feature I am seeing consistent between desktop and Firefox for Android is the about:cache page. This will give you an idea of what is stored on the cache and the offline cache. You can list the entries as well. Offline cache storage needs to be asked for access to for certain sites.
I recommend making a feature description in [bugzilla.mozilla.org]
