Use the damn cache.” Reproducible: Always Steps to Reproduce: 1.Forget your skype password. 2.Use the forgot my password button. 3.Use the link to change your password. 4.Get redirected. 5.Use the back button. Actual Results: Get angry, 'cause Firefox annoys you with that question and does not offer the right answer. Expected Results: Just shows the page that I left as I left it without sending any data because pages in cache don't need any interaction.

The old data was expired from the cache, normally on request from the website itself (like a no-store header). Other browsers resend the data without asking your permission. This can result in errors like a credit-card purchase (!!).
