Rated 5 out of 5 stars

The idea is really great, but it can't be used together with forecastfox. My weather addon will unavoidably hide it, so a fixed button in the add-on bar is NOT nice. I'm not the first to complain about it, why is it still not mobile in about a year?

Edit: I can now use it, but just because CoolPreview's icon separates ir from the place forecastfox has its weather data.

More editing: I think there's something wrong with my add-on bar anyway. Everything is not mobile anymore, now that CoolPreview's icon is preventing Trust My Web's one from hiding.

This review is for a previous version of the add-on (1.5.1-signed.1-signed).
