Upgraded firefox...lost weatherPRO! ...Otherwise a 5 star plus extension. Been using for years. My day seems lost without it. ...One hour later... Still does not show up in my task bar. Ok... got it working...and we're back to 5 STARS!!! Windows 11 seems to handle extensions a little differently, but I take the blame... I missed one step in the extension process. *****...that's 5 Stars!!!!
