No, the opposite is bad. You should not visit links posted on this forum with a regular browser. But also, you should not log into any sites over Tor if they are linked to your identity. Don't log into your email account or Facebook over Tor. Keep your real identity and your Tor activity separate. (Ideally on separate physical machines, or real ID on host OS and Tor activity in VM, or real ID on hard drive and Tor activity on bootable distro, etc., but at a minimum, don't do anything linked to your real identity over Tor)
