Ok, we've switched to that URL from https://adguard.com/en/blog/firefox-manifestv3-chrome-adbloc.... Thanks!
I guess we'll keep that article's title though (in de-baited form) because "Manifest v3 signing available November 21 on Firefox Nightly" would trigger weird responses.
Edit: nope, reverted. See https://news.ycombinator.com/item?id=34851017.
