Look, just trust your Uncle Fuzzy on these two:

Log in to your Facebook account. In the upper-right corner, click on Account and then click on Account Settings. On the My Account page, find the Account Security line and click change. Check the check-box under Secure Browsing (https) and then click Save. Thanks.

Log in to your Gmail account. In the upper-right corner, click on Settings. Look for the Browser connection section and choose the Always use https radio button. Scroll down to the bottom of the page and click Save Changes. Gracias.

Oh, and then go back up your important documents. Because I know you haven't for a year and you're going to come crying to me when your hard drive crashes. Crimeny.
