Same problem occurs in similar vpn addon. But Hox vpn works smoothly in chrome browse.! How it possible.?

Having the same issue - fresh install so looking for a VPN addon.

Happening with Hoxx and with SetupVPN - exact same issue: Click on password field and the addon minimises. use Tab to get to password field - same thing.
