Is there a way to set maximum cache size or to change default cache directory to sd card on Android?

I'm low on space in my Android Phone and Firefox Cache is huge by my phone standards. I have to clear data after each time I use firefox. Firefox is great but I'm using it less and less, day by day. I browsed Internet for tips, but while I was able to set a cache directory on sd card using "about:config", it still writes on phones internal too. It seems it duplicated cache.

Setting a different max size using "about:config" only works temporarily, because it seems Firefox returns to default after a while.

Thank you.

Hello.

To help automatically clear up some cache from Firefox, click on each of the images from left to right. Now at least you won't have to constantly do it yourself.

Also, to help you with your space issues, download Clean Master from the Google Play app Store: https://play.google.com/store/apps/details?id=com.cleanmaster.mguard this app will clean up hidden cache and useless files on your phone, helping free up space.

And as for why Firefox keeps reverting to the default cache in "about:config", I do not know. We are sorry for any inconveniences that this has caused you. But please try doing what was mentioned above to help with your issue.

Hope this helps!

Deleting data that way doesn't seems to work...2 or 3 web pages after, and I still have 5 Mb of data to delete (using android definitions - > application - >clear data) after quit firefox.

It might be worth trying the Firefox addon "Self-Destructing Cookies". Whilst this is primarily designed as a security/privacy addon, it can be set to clear the cache after a user-set number of idle minutes.
