McAfee's SiteAdvisor doesn't have a problem with them either...

There is nothing to be 'afraid' of, though it is always best to run as light as you can- FF will start way faster if it isn't firing up a ton of EXT's... Even so, turning them back on won't kill you. The one that tips it over will be identified soon enough, then just go in safe and take that one out...
Are you running fine then?

I don't know that, but usually a websearch with 'spyware adware' plus 'whatever is in question' will bring a ton of hits if it is bad.
