It's about google's shenanigans aka Manifest v3 aka North Korea, so, the script managers succumbed to google have slow connections because of that MV3 or maybe bug in it, that is relevant for Tampermonkey for example.
The script managers who don't wanna live in North Korea will be banned by google eventually, like Violentmonkey for example.
You should add more info and context to this warning:
Bug detected: Chrome/Chromium! The script works slower and may soon stop working at all. Install Firefox to fix!
