As of bug 451250 undoing the close tab of an expired form post will no longer trigger a POSTDATA warning, so the workaround in bug 378160 is unnecessary. Steps to reproduce problem: 1. Submit a form that uses the POST method 2. Close the tab 3. Clear the cache (not necessary for some forms, such as bank logins) 4. Undo the tab close Expected result: Error page because the page is no longer in the cache Actual result: Browser tries to visit form result as a normal page Note that the whitespace cleanup in the checkin for bug 378160 should stay!
I backed out bug 378160 locally but can't reproduce the STR in Comment 0 I mean I don't get this: > Expected result: Error page because the page is no longer in the cache I tried to clear cache via Tools->Clear Private Data and also via Preferences->Advanced->Cache
