Simple firefox/internet explorer plugin

Hello, I Have website and some bad people try to do phishing using my visual and fake url by email. So what i need is a simple plug in that will open a popup or something like this that say this email is fake !! example my url is => [login to view URL] - and the anchor look like [login to view URL] so this is good but the plugin have to check the real hyperlink to be the [login to view URL] and not http://otherbadsite.com. If you can do the job also for internet explorer it would be nice. In fact it simple job the script have just to check the real hyperlink if not the good one it will open popup to say something like "attention it's phishing email !! thanks and good luck
