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.
These kind of addons require the 'access your data for all websites' to get access to the image that needs to be converted. The permission structure of add-ons does not allow for a less intrusive permission to get this information. I am looking into adding support for animated images, however this is much harder than converting a static image so I can not give an estimate when it is ready.
