Reading about the Heartbleed Bug, and the NSA having readable access to the Tor network, I can't really answer this question myself.
Is logging into any account on a website using https, in technical terms, as secure as just browsing the Internet?
From what I have understand, Tor randomizes the path packets use for different sites etc. Assuming that there is no Tor server in my paths that is leaking security (like with the Heartbleed bug) are my packets still encrypted in a safe way, so that no man in the middle attack can occur?
Please note that I don't want to discuss the security of the account, just the technical security, in terms of delivering the packets on the wire.
