I remember it was OK before (couple months)
updates didn't help as well as downgrades (it helped little bit - some pages are now much better than before BUT may be they could change code of page)
in safari and firefox everything runs well
i have last update of flash installed
in preferences I set Enable Plug-Ins
in config#UserPrefs I set Enable On Demand Plugin
There was also problem (now it's allright) with youtube - I couldn't use any button (play/pause, volume...) - and when video was embeded everything went well
some pages are moved to side too much for example:

Thank god somebody from another forum helped me. His reply:

Expand the View menu and disable Fit to width. You may also have set a default in Preferences: Web pages: Fit to width.

Fit to width changes the color in some cases where the contrast could be unreadable because of layout reflows caused by fit-to-width.

The feature is intended for smaller screens or for when you need a better reading experience.
