When I submit a form and then press back, I sometimes get the message "Document expired" instead of the last page.
I used to get the following annoying message box instead (which now appears after a click on "Try Again"):
Now, I do know what this means and why Firefox shows this message. However, I want to just see the last viewed page instead - just as it was displayed a second ago. No popup, and no reloading to reflect the server's new state. (Maybe a little info bar would be nice, but it's not neccessary for me).
Use case: Imagine I logged in to a site I regularly use, and after pressing Enter I see in the corner of my eye a news headline on the login page. I'd like to click back and see the exact page I saw a second ago to click on the headline. If I view the front page logged in, or just reload it, I might get different (randomized) headlines.
So how do I get rid of the "Document expired" and "Confirm" messages completely and get Firefox to simply display the cached last location after submitting a POST form? about:config
settings, extensions, proxy tricks are all fine.
