Color issue with certain links
https://gf.zukizuki.org/en/scripts looks like.
Doesn't look like that to me. Either it's been fixed or there's something happening on your end.
Okay I tracked it down to a custom theme this fork of firefox uses. Disabled it and all is golden. (pardon the pun)
Weirdly I've never seen it applied on other sites - and only on GF since a recent update. I'll report this to their theme designer.
I don't know if this is related to https://gf.zukizuki.org/discussions/greasyfork/295912-text-color-issues-in-dark-mode ... Certain links on the site are now orange/red-ish -- this is what it looks like with Ublock and Tampermonkey turned off, nothing in Stylus running to change link colors, and userContent.css seems innocent.
