I recently had money taken from my bank account by a dubious company, it was for a subscription which i cancelled. While looking through my firefox browser history i found the link to where i had cancelled the subscription but to make sure it was correct page i clicked on the link again. The problem is browsing history now lists the site with the new date it was clicked on and shows that the page has been visited 2 times. But how can i show the original date, so that i can prove that i had cancelled my subscription on the original date?

Any help on this would be gratefully appreciated.
