Reddit Deduplicator от Nick Gaya

When viewing a list of posts on reddit.com, the extension finds posts with the same URL or thumbnail and groups them together, showing only the first instance.

This is particularly useful when viewing an individual user's posts, as some users will post the same link or upload the same image to multiple subreddits. It can also be useful for viewing subscriptions or multireddits that aggregate posts from similar subreddits.

This extension is compatible with Reddit Enhancement Suite's "Never Ending Reddit" feature.
