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.

I feel like i need to update this, and think to myself there's no way to set a shortcut key so when holding a key on keyboard then left clicking the image should activate this addon, but there's no way to do this, I had to remove stars because multiple images is a tedius 1990's download caveman jobs

Would never want an extension to save to a less efficient format. Need the other direction, to save to AVIF OR JPEG XL.

Do not sawe image

wish this extension would convert webp to gif :(

Does not work on Windows 7.
