Peter from the Electronic Frontier Foundation writes, "Over at EFF, we just released a version of our HTTPS Everywhere extension for Firefox for Android. HTTPS Everywhere upgrades your insecure web requests to HTTPS on many thousands of sites, and this means that Firefox on Android with HTTPS Everywhere is now by far the most secure browser against dragnet surveillance attacks like those performed by the NSA, GCHQ, and other intelligence agencies."
I installed it today.
Android users should install the Firefox app and then add HTTPS Everywhere to it. Iphone and Ipad users will unfortunately have to switch to Android to get this level of security because Apple has locked Mozilla Firefox out of their platforms.
