This happens if the reloaded page has less iframes than the last page. In the example we can reproduce it with iframes but we also saw it with other external? content. Reproducible: Sometimes Steps to Reproduce: open http://www.raikosoft.com/reloadbug/main.php you can download the page source here: http://www.raikosoft.com/reloadbug/reloadbug.zip The page uses 4 seconds sleeps to show the behavior better. On the page there are two iframes: one shows the text "Top" in a red iframe the other shows the text "Bottom" in a blue iframe. The blue iframe is shown always. The red iframe is shown by random. 1. load the page http://www.raikosoft.com/reloadbug/main.php until you see both iframes. 2. press F5 3. press F5 again within 2 seconds (while the page is still loading) 4. repeat step 2 and 3 until you see the red "Top" iframe under the hr line Actual Results: The content of the red "Top" iframe is shown instead of the blue "Bottom" iframe. We think this is not an iframe problem but a problem with content which is loaded in background. If you load a page while the current page is still loading, perhaps the background threads? are not canceled. So the content of the last page is shown in the new page. You can also reproduce the bug with the forward/backward buttons. Feel free to contact us for additional infos.
I can confirm this bug. We have been seeing this on our website for 1-2 years and still happens on the most current version of Firefox. The problem usually happens if a page contains several iframes (usually ads). On subsequent pageviews or refreshes, the content of an iframe in the previous page can show up in a random iframe on the current page. I always assumed that this was such an obvious bug that it would get discovered and solved soon, but apparently it still exists and this particular bug is not even confirmed.
I can confirm the bug too. In our website we are experiencing the issue time to time. Our solution was to give up on some of the iframes on the page since the early versions of firefox 3.x.
I can confirm this bug, its happening on my website too. Im surprised about this since in all other browsers this not seems to happen.
