IE <= 8 support

In IE8 all the colors and content from accessibility bar buttons disappears while first using the block. The issue itself wasn't solved because after some time researching I wasn't able to find a cause of the issue, and there is a problem with testing on IE8 since it's old browser. So compromising solution was implemented: JS script was disabled for IE <= 8 because HTTP mode works normally. However applying background colors to all element still doesn't work...
