Make the href in each link more visible when a mouse hovers over so the user doesn't accidentally click on an unexpected (and potentially spam) link
By default, in Chrome, if you hover your mouse over a link (aka an <a> tag in HTML), the actual URL shows up in the lower left corner, which is both hard to read and hard to remember. Many spammers will hide malicious URLs behind what seems to be legit/safe text. 😕
This script will copy the actual URL and display it in a blob right next to the link (instead of the default lower left corner of the screen - which is far away) so it's easier to tell what you are clicking into.
Please see the screenshot attached to see an example from a spam email that pretended to be FedEx.
