I have installed Norton Fammily to my Kindle Fire HDX. The latest version I got from Amazon Store is 3.0.0.274.
I tried Silk Browser, the NF could block some contents, but if I closed NF from task list, those contects wouldn't be blocked. The worst thing is, if I use priveate browsing, the NF will block nothing.
Is there any way to upgrade 3.0.274 to newer version?
