I have a new Microsoft Surface tablet. I thought I downloaded Mozilla/ or transferred it from my old PC computer where it is my primary. First there is no "Home" tab. Second, I have renewed my VPN,which was recently due to renew, and I believe it is downloaded onto the tablet, although I can't find any icon for it. When I try to download it again, I get an error message that this app is only supported by 64 bit devices? So, does that mean my Surface tablet doesn't have 64 bit capabilities? I'm confused. Thanks
