And here is a print screen: Link

Is the problem with displaying the page, or printing it?

In the address bar, type about:preferences#content<enter> Across from Fonts & Colors, press Advanced

Turn on Allow Pages To Choose about half way down the page. Restart Firefox.

Hi FredMcD - this problem concerns only displaying websites, especially based on templates from envato marketplace. Yes I have enabled "Allow Pages To Choose", as well JS and support for dynamic loading images, but it's not solve my problem. I don't know what happend. Any idea?

Ok, the reason was a driver graphic card, so I installed older version. Thank you FredMcD for your time and help! :)

If you have problems with current Shockwave Flash plugin versions then check this:

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

• about:config page: layers.offmainthreadcomposition.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
