Extensions are enabled in add-on manager but do not appear on FF4 On a Macbook Pro. Norton Safety Minder, Forecastfox Weather, Invisible Hand. All are enabled but none display. Is this a known issue. What to do?

Installed v4 today. (22 Mar 2011) Does not appear to be an RC. Had been using v 3.6.15 and these items appeared to work fine. Are they erroneously shown as compatible until updates are made? Who needs to make update, FF or extension source?

I doubt if that Norton extension is compatible, Symantec usually takes a month or so before their extensions are compatible with a new Firefox release version.
