Very simple, from the source:
Lemmy Universal Link Switcher, or LULs for short, scans all links on all websites, and if any link points to a Lemmy instance that is not your main/home instance, it rewrites the link so that it instead points to your main instance.
In essence, any Lemmy link you come across is automatically redirected to your home instance.
Can be installed with Tampermonkey or ViolentMonkey (or similar tools).

This is a bad idea. Hear me out:
You click on a link to
lemmy.worldto a post that has hundreds of comments. Instead, you get redirected tomy.instancewhere this community is not federated. The post is immediately federated and loads, and you see the post on your home instance.But no comments. No future comments, nothing.
A better method would be to have just “action” links go to your home instance. I.E. up vote, comment, save, etc.
