Works like a charm, as far as I am concerned.
At first, I thought it was a shame it saved the image in .png but I then realised that plenty of options are available in the extensions parameters.

Marche à merveille, en ce qui me concerne.
Au début je trouvais dommage que l'image soit enregistré en .png pour ensuite réaliser que pleins d'options sont disponibles dans les paramètres de l'extension.

So far so good it works, don't know anything technical but it converts .avif to png format just right click on images and convert and then save location, don't know why .avif even exists it's a stupid format and firefox needs to fix this as I dont really like using alot of addons, it takes up memory in total, but this one is 5 star unless there's an issue in the future at some point.

Programmer deserves donations for this so if you're rich donate to the guy and buy them some coffee and a snack.

So far it runs smoothly in Firefox 115.17.0esr under macOS 10.14.7 Mojave.

As an artist who needs to save images for references and is not a fan of converting WebP just to view them, this app is a life saver. Thank you.

So stupid that you now need an addon to do something that browsers have been able to do natively since the 90s: download an image in its original file format. Why, Mozilla, WHY!? Thankfully this exists, but it shouldn't have to.

все прекрасно работает!

Very useful & productive... best converter till now

Really good for quick image downloads, thanks

Opera ?

Does what I need it to do, which is download wallpapers from reddit in a sane format

This has been a god-send! WebP is such a pain to work with, so being to just convert it to something more usable has been worth the couple extra clicks.

Extremely non-intrusive and easy to use. The best extension I've found for dealing with .webp (and image conversion in general)
