A proposito de iste extension

Features:

Shows only the image file on i.redd.it and external-preview.redd.it and reddit.com/media?url=IMAGE_URL (only on Firefox) pages.
This improves loading speed, removes trackers and fixes the broken zooming.
Redirects preview.redd.it to the i.redd.it equivalent.
This gets you the highest quality image, and you can download a PNG/JPEG instead of the default preview.redd.it WEBP (which you most likely don't want).
Blocks an icon file request on the image file pages, since they don't have one.
The browser requests an icon for every page, but since they don't have one, blocking it is a tiny bit faster than sending the request and finding out that the destination doesn't exist.
