I use Mozilla firefox to go online. When I've opened an email I've received and then want to return from that email to the email list, I click "backspace." Half the time, it gets me back to the email list. The other half the time, a window pops up, saying:

"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier" and I have to choose to cancel or resend. I always click resend.   I don't want this window to pop-up. When I read an email and then hit the backspace key, I just want to get back to the email list.

Can you help? Thanks, Alvin Glazerman
