The display area in Firefox suddenly becomes scrambled with wired scrambled pixels
it happens more often when I scroll the webpage with mouse wheel
a zoom-in or zoom-out (by Ctrl-mouse wheel rolling) could refresh the display to normal
reinstalling firefox did not solved the problem

Could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.). Then perform these steps:
- Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
- In the Firefox options window click the Advanced tab, then select "General".
- In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
- Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
Upgrade your graphics drivers to use hardware acceleration and WebGL
