Right now, if you use the extension to upload an image from twitter, it uses a name without an extension, which causes browsers to download it as binary garbage instead of displaying it. If you rename the file it has the right data and can be displayed, but this is very annoying. It would be awesome if the extension could detect the image filetype and add the appropriate extension if it's missing.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Catbox Uploader requires very minimum permissions.
