InformAction Forums

The above was posted with Developer Edition, which doesn't have the problem. Now back on Nightly, this forum is not bad either, same for Mozillazine forum and Bugzilla. Yahoo is a nightmare, though, freezes the browser every time a new ad loads.

I use Process Explorer to monitor resource use, slowdown is worse when plugin-container.exe is using a lot of CPU. MajorGeeks home page, which has no embedded media, loads fast.
