Firefox freezes at sites that have flash content after suspend

As is said in the title, I got this problem which is reproducible. Every time after I resume from suspend, firefox freezes up to 7sec at “flashed” sites. That is very annoying.
If I disable the adobe flash plugin, it is smooth without flash.
If I restart my laptop, everything goes flawlessly.
It did not help if I restart the X service.
This also affects the chromium on both the smooth scroll and the freezing at flashed sites.
Additional information:
Opensuse11.4 32-bit KDE.

Anyone has an idea???
Please help…lol!

Somebody Help~~~~
