Imagus Reborn Hababr מאת

Enlarge thumbnails, and show images/videos from links with a mouse hover.

Sections on the options page, and their brief explanation:

▪ Sieve
An expandable set of rules for getting the larger image, media or other content.
It has more than 800 rules by default, which support thousands of sites across the web, including the popular ones such as Reddit/Imgur, Wikipedia (or any WikiMedia based site), deviantART, Google services (Images, YouTube), Facebook, Twitter/X, Flickr and many more.

▪ Grants
List of user defined rules for blocking/allowing specific sites.

This extension is based on the original Imagus extension (by Deathamns) and has updated sieves and many improvements.
