Apologies if this is a bit hard to understand.
Some sites have a background that fills the screen… until you scroll. There’s one on my work’s intranet, so obviously I can’t use that as an example. But I see the same thing on my Lemmy instance, db0 (not mine mine, the one I use). They made this thing, I think it’s meant to be a black hole, heavily blurred, but when I scroll, the image scrolls away.
Is there some way to lock the background in place and let the content just scroll past it? Maybe with a setting, or more likely with an extension?
This is something that a web designer / developer does. It’s not a Firefox feature or controlled through user settings. However, you are right, that one could probably make an extension that overrides the original setting and forces a different behaviour.
I figured. There’s probably a line in the code somewhere that defines the image, and there could be a line that tells it to scroll with the content, or remain static and not scroll off screen, but it’s not there and it’s piss poor design.
Fun fact: the Lemmy instance I use does do it in the Inbox, just not the news feed.
