I have no idea how to file that bug in BMO and I'm not even sure it's a BMO bug since it's more probably a Flash plugin bug so let me describe it here:

  • the Firefox 3.6.8 home page recommended me recently to update my Flash plugin on my Mac OS X box (Snow Leopard)
  • so I did...
  • since that day, many web sites showing Flash-based videos freeze making the browser totally unusable with CPU usage > 95%. A good example is http://lci.tf1.fr/
  • I originally thought a bad interaction between Flash and AdBlockPlus was guilty but I removed ABP and the problem is still here ; the Flash plugin is almost certainly guilty here

The new Flash plugin was probably pushed to users for security reasons. But for UX reasons, it's probably better to stop pushing it until this problem is gone...
