background image stretch in html not working if 'never remember history' is choosen
I have a problem that did not exist in previous mozilla versions. I found the problem after installing the most recent version and after setting firefox to "never remember history"
The problem is related to the CSS code for stretching a background image to fit the screen. The background image does stretch if "never remember history" is NOT set. Only part of the image is displayed and the rest of the background is black. I first noticed it with my website www.missionbayhighalumni.com and later found that the same problem also occurred with this website: http://www.htmlite.com/faq022.php or http://www.htmlite.com/faqEX004b.html
I created several test cases with very simple code, all had the problem. The background image stretch code tests all work for other browsers and even firefox if "never remember history" is not selected. It also appears to be intermittent.

Looks fine to me and all containers have a height:100%, so that is also correct
You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of the involved files.
It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
