Comment 145 for bug 240242

I exchanged email with the Flashblock devs, and they say the window-handler issue does not happen in the Flashblock sources. That agrees with #112 above ... something other than the window-handler issue can cause this bug. I've tested Firefox 3.03 (the latest at this moment), and the bug appears after a few hours with Flashblock installed, and I never see the bug if Flashblock is not installed, so the problem is something to do with the Firefox/extension interaction.
