Sure, that's no problem. But this doesn't help. I just spoke with my nephew who's pretty smart about stuff like this, but he had nothing to suggest which hasn't been suggested and tried.
Just to review, to clean my cache and cookies, here is what I did:
I opened up Firefox; and went to Settings.
I went to Delete Browsing Data.
I selected Cookies and Site Data; and selected Cached Images and Files.
I deleted this browsing data.
I then Restarted my phone.
I figure this about covers it, but anyone have any additional comments or suggestions?
