My Mom has an RCA 10 Inch Android Tablet. I wanted to know if anybody can help with the FireFox Browser She has Running on it? Whenever I had a Tablet and My FireFox Browser or any of My Apps Ran Slow I would go into the Settings. Then Open the App that was Running Slow and Clear Data or Clear Cashe. My Moms Tablet is Running Android 8.1.0 and Her FireFox Browser is now Running Slow. So I go into Settings then Open Apps then Open FireFox. It has Uninstall or Forece Stop. Then it has See Data Usage. Then it has Permissions. How do I Clear Data or Clear Cashe of FireFox? I Hope somebody can help?
