Very good addon!
Could you please add the quality values beside each format slider? And give an option to always show the "Advanced" panel instead of the "Basic" panel?

Seems like good addon that does what it says, however, I specifically needed to convert animated WEBP to animated GIF and this addon will only convert to JPG or PNG from WEBP. If at all possible, please add this ability! I'm also not sure why this sort of addon needs permission to 'access your data for all websites.' Be careful when choosing to install this.

sort of works but won't download gifv/webp to animated gif which is what I wanted it for. No option to save webp as gif, either

At first I didn't even realize I had to choose a special new "convert and save" option from the context menu. I would rather if this add-on worked within the normal image save function. It's extremely annoying that it doesn't apply the image files' existing name, and instead only wants to name everything "latest" with no filetype extension. Each time it chooses the default download folder instead of remembering the last folder used. At least it works, and offers *some* solution, but it's only halfway there, so I rate it effectively half score.

The plug in work but it creates files without extention like "latest" and not "latest.png" so we have to do it manualy. Maybe it could be cool to have it in the options. Thanks ! :)

It works but you have to manually change the file extension.
