For almost two weeks, the temperature shown on the status bar has been 41.9°. As you can see from the attached screenshot, the current temperature is 51.2°. “Retrieve weather” does not change it.
I am using WWL v. 1.0.23 with Firefox 34.0.5 on Mac OSX 10.9.5.
This extension has been discontinued. If interested, you can try the Windows desktop version of Weather Watcher at http://www.WeatherWatcherLive.com.
I think you missed where I said I was using Mac OSX. A Windows desktop version does me no good at all.
