Slow scrolling in Firefox 3.6.3

Lately firefox has become very slow in scrolling on certain like

www.blabbermouth.net

and I can't figure out why. I have tried to run firefox with clean profile and no plugins and the above site is unscrollable in firefox. It runs great in Konqueror. Then I thought maybe it is kwin's desktop effects that are killing the scolling performance but shut it off doesn't help. The strange thing is that firefox on Ubuntu 10.04 runs much faster on my machine at which an old p4 machine and my machine at home is a quad core pc. Is there something different about firefox in Ubuntu and Arch Linux the way they are build? Can anyone else use the site above in firefox, meaning can you scroll?

Re: Slow scrolling in Firefox 3.6.3

By the way I'm on 64 bit by that way also at work with Ubuntu. Scrolling has for me become much worse with firefox 3.6. I don't know if it is the flash plugin. Ubuntu seems to use the 32-bit plugin plus the wrapper. I'm using the native 64 bit at home. Can anyone maybe clarify what flash runs best on 64 bit? Native or the wrapped 32 bit?

I'm on an old 32-bit P4 and I can scroll on that site w/o a problem. Check that site w/ chromium - gamespot is horrible w/ firefox but runs w/o a hitch in chromium for me.
Maybe smoothscrolling will help you. You can also you PgDn / PgUp instead of the mouse wheel.

Might it be video-card related? I had similar issues with my ATI Radeon card... With the latest Xorg-update, I had to install Catalyst again to make it work correctly (dri-related if I'm remembering it well) Maybe you should check X.org-log?

Try

export MOZ_DISABLE_PANGO=1

in your ~/.bash_profile

Already turned on but it kills scrolling completely on the above mentioned site for me at least.

Found the problem it is the flashplugin. When I remove it the site scrolls perfectly. The previous alphas of the 64-bit flashplugin ran much better. Do anybody have better succes with the 32-bit and nspluginwrapper?
