Probably the best around.

Update - in the latest version, I have two forecast bar, one - mine in left top corner, while there is the other for New York with different units in the right. Working with the settings, I see nothing to remove the unwanted bar... Would be nice to fix that

I've been using this add-on for a very long time before it changed hands. The new author has been doing great though it needs a patch to fix HTTPS Only Mode. But another add-on "HTTPS Everywhere" will still work after you disable the setting in FireFox. Awesome weather add-on!

No longer works with firefox 83, even with "https only" disabled.
Edit : Thank's for your responsiveness and the last update (4.26). It works very well again.

Easy to use and setupands its accurate too!

Has an amazing level of customization!

Stopped working on Firefox and Firefox Nightly even with no script disabled on Linux Mint 20 Ulyana.

Don't work with user_pref("dom.security.https_only_mode", true); in FF79 o_0

best weather app i found here :)
