Every time my browser refreshes I get the pop-up To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier. Resend Cancel" How do I get rid it?

Question

It has never done this before. I play a game that constantly refreshes the page & have never had problems before until yesterday. I have looked in tools and there's nothing in the option section that will let me stop it. Is there somewhere else to look?

Perhaps someone should report this to MarketWatch. There are ways for web developers to work around this issue (GET after POST, for example).
This is a longstanding issue. Examples:

In past discussions about this message, I have never seen an easy solution. Arguably it should be made a user preference: those who prefer to be warned about the risk that they will double-submit a transaction or instruction on a poorly designed site can have their warning, and those who prefer to take their chances can take their chances. Not sure whether that is on anyone's "to do" list.
Separate issue: I wasn't aware of any difference between 3.6.12 and 3.6.13, but both are riddled with security vulnerabilities so it's hard to recommend using either of them at this point.
