hi aduboyce53, addons are created by independent developers - we are not able to provide support for them in this forum. if you have questions or want to report problems with the extension, you can find the support forum for users of forecastfox at https://groups.google.com/forum/#!forum/forecastfox-users thank you for your understanding!

Specifically, which extension do you have installed, that added that Weather Bar? That's not a default feature in Firefox.

If you are using ForecastFox, that extension hasn't been updated in a long time and few potential users can even get it to install lately (like maybe since Firefox 29 was released). Also , it was broken for awhile a few months ago when the domain registration expired, but came back for me after a few days. I don't use it everyday, just spot checks using a different Profile - never worked too good in my everyday Profile, there was a conflict with an extension that was more useful to me.
