I've got the latest version of firefox installed, yet I'm constantly getting messages that it's outdated - on Mozilla's site as well as many others. I've deleted almost all of my plugins and extensions (and updated those I do use - though the Moz update your plugings page seems to have trouble with Shockwave Flash as well) ... and I still get the error. The only thing I can think of is that I've somehow been too aggressive with my NoScript forbidding.
