Was looking today for a simple, secure alternative browser to replace IE in my off/online wallet in a VM (https://steemit.com/wallet/@madmac/a-secure-off-on-line-wallet-approach-for-multiple-cryptocurrencies).
Eyes fell on brave.com and this one seems to be something to keep an eye on, so far it is still under development for Windows, stable for Android and iOS. Works pretty well.
If you need an alternative to the Google and MS spies, to make a small box a bit safer, here you go. I have no affiliation with them whatsoever.
