I've been using g-mail for a while but just started receiving a message at the top of my mailbox screen in a red box that says: Your browser's cache is full and may interfere with your experience. Next to the message, there are two clickable links. One says "fix this" and one says "hide". I haven't clicked on either because I don't know what will happen.

Does this happen to anyone else? Should I click on the "fix this" link?
