After upgrading to Firefox 3.6, I noticed it preserved the old behavior for existing profiles. Only new profiles will default to the new behavior. Good intention but as I create new profiles, I now have different profile with different behavior, which is a little bit annoying.
Luckily this feature can be enabled/disabled with a few easy steps:
1. Go to
3. The default value is
true. Change it to
falseif you want the old behavior
