Is Logging Into Two Separate Accounts Okay In the Same Browser?

If I am logged into Myspace, and I open a new tab and log into an email account, does Myspace see the email account that i am logging in to? Like say bobdobbs@yahoo.com? Do they see that?

 

If there are no security flaws in both services it's secure to log to both.

 

Any website you visit may be able to sniff your history - see Any website you visit can determine where you have been on the Internet unless you have suitable protection (e.g. NoScript add-on w/Firefox).

Once they have your history, and if you visit a compromised website (simultanelously) with MySpace and your email account, with the information gleaned from the cookies and any cross-domaim scripting vulnerabilities in your browser - well, you may be vulnerable to an extent. Like ResoMail said.

My advice would be to visit those sites where you login, one at a time, then wipe your cookies and history immediately after, or use different profiles or even different browsers if you are really paranoid.
