Tried most weather addons - Weather Extension has the edge.
The layout is sleek, professional looking, offering an intuitive forecast at a glance which works well with dark and light Firefox themes.

Features like future-forecasting, f°/c°, dark/light themes and links to full page maps are included for free, and there's no intrusive nagging to upgrade. The extended customisation options and alerts are well worth the price of the premium version.

In terms of additional features, I'd love to see a one click option to view the forecast and radar in the same page. But I can spare time for two clicks :D

Great work!

Great app that is simple to install. Immediate response from the developer to questions. A+

I have used several weather extensions in Firefox and this is a good weather extension. It has more information and is easier to use than any of the others. I highly recommend it.

A super handy extension. I love it and use it several times daily, looking at weather conditions in multiple cities.

Best weather add-on available! Excellent customer support!!

Just downloaded this extension and happy with the results. Have been using WU website with success but like having an extension on Firefox. So far so good! Thanks Tim! Just got upgraded to Weather Pro by Tim and I am loving all the features! The animated icons, quotes plus the other features including alerts give me everything I need in weather app without having to open another browser tab! Definitely a must have extension for any browser. Thanks again Tim! ;)

Cool app. Very handy for a quick check of weather conditions

Really like this extension, everything you need without going to a bloated ad-heavy page 5 stars

Ammazing extension!

Great app. Very compact and has all the necessary weather information.

I love this app!! Precise and accurate weather and easy to use!!

Easy to use and setup, best weather extension I've used.

Very nice, easy to use and works with Firefox very nicely. I live in tornado Alley as it's called so watching the weather and having it accurate is very important to us.

This is the first weather add-on I've tried that doesn't either slow the browser or shut it down completely. I love it!

Great weather app, fast, easy to use, clear and concise data presentation.

Maybe my favorite add-on right now. Excellent dev support too - When I had a problem, Tim quickly and politely solved it.
