When backspacing, will frequently not load the previous page. Below is the error message I continue to recive.

The requested document is not available in Firefox's cache.
As a security precaution, Firefox does not automatically re-request sensitive documents. Click Try Again to re-request the document from the website.

You can get a "document has expired" message if you use the Back button or a bookmark to go back to a specific page and the web site has instructed Firefox not to cache the page. Firefox tries to retrieve the page from the server, possibly by sending POST data that is no longer valid. In such a case best is to open links from such a page in a new tab/window by middle-clicking a link to avoid using the Back button, but instead close the tab to return to the previous tab.
Been using the same programs for years and this is a new issue. Working with the backspace button has always worked in the past. It's happening in multiple programs on two separate computers.
Is there a way to instruct the server to allow Firefox to cache pages? Although I don't think that's the issue because my work-around for this has been to resend the page and it pops up. Thanks
