This addon provides special support common cookie blockers doesn't have.

Unfortunately, often it blocks the nag screen but not the grey overlay (e.g. https://www.foto-erhardt.de/kameras/vollformat-kameras/nikon-z9-gehaeuse.html).
Besides, it prevents other cookie blockers from doing their job...

I am not much of a programmer, but very experienced in testing ad blocker addons for FF for about 10 years now. For years now "Adguard", "Super Agent" (has AI) and "I [still] don't care about cookies" (static list - always up to date) are outstanding winners for cookie consent. But I think the most honorable engine is included in "Cookie-Banner-Blocker" (otsmr) as it contains multi-level detection but continuing development is abandond by now.
You should add the latter engine to yours and make an exception for Google explanation pages as reCaptchas as well (as Cookie-Banner-Blocker has a false positive there too). Then its likely your addon could become popular in a way like "Super Agent" or "Adguard" easily.
