Question Chrome extension that lets you know if you've already visited webpage you're on?

This extension can change the color of the link that you already visited (normally blue for new links, purple for visited links).

I will be accessing the pages directly, rather than through links, so I would need something within Chrome's UI somewhere to basically let me know.

Maybe the address bar color changes? Or an icon next to the settings menu that changes color if I've already been on the webpage?

It's the links that change to purple color.

Anyway once you are on a page, you should know whether you have visited it because there will be some links on the page with purple color.

I enter competitions.

I click on a link to a competition from a website that uses images as links.

When I'm on the resultant webpage, there's a form to fill out.

I want to know if I've been on said webpage before.

There will be no purple links on either page (first uses image as link, second uses a web form).

I see the problem, most of extension only work with text links, you can't change the color of a clickable image if it has no border at all.

It seems that you need a custom extension that works with images, photos...

Ideally, I need an extension that, if I'm on a webpage I've visited before, the address bar changed color or the extension icon changes color or something.
