Why is my browser trying to pull content from several other Lemmy instances?

I run a pretty locked down Firefox browser and I noticed when browsing lemmy.world that the browser wants to pull stuff from a long list of other instances, which fails because they aren't trusted. Is this normal? I thought an instance would collect the things you are subscribed to and store them locally so that you didn't have to go talk to 20 different servers. Not true?

It's definitely not only static content tho, I block third party scripts with uBO and it shows other instances domains in the blocked list.

Edit: I was mistaken, it's just images

Interesting, I dug through my networks requests with ublock off and I don't see any remote scripts. Only requests to media.kbin and lemmy/pictrs locations on various instances. Any idea which pages you're seeing that on?

Well I was wrong, I checked my network panel and it's definitely just thumbnails that it's fetching, I'm dumb I thought that only domains that served scripts ended up in the uBO matrix panel, I did a test and it does that with any third party content instead, static or not :p
