I have not had this problem before with other phones. I began using firefox again today with my Samsung Galaxy Centura. Occasionally, while a page was loading, I would suddenly find myself off the web and at my phone's home screen (not FF homescreen). I disabled the cookie destroyer add on but that did nothing to help. The only other add on's I have are anti-FB phishing and Ad block. I have always used these without incident. What could be chronically throwing me off the internet? My ram is fine, memory,cache, etc. Thank you for any suggestions you may have.
