Do you use Google mail? If so, be careful if you get a message like this:
Dear Gmail User

This is a phoney email – the idea is to get you to click on a link, go to a dodgy website that looks like a proper google page, and then reveal personal information. Firefox (or someone) is doing their best to block this – when you click on this particular link, you get a warning screen before you go to the dodgy page.
But be careful – there may be similar messages around, with different links.
