I've tried several extensions for this problem but they didn't work properly. Have you tried this one, and does it work for you?
I'll give it a try as well.
Thank you.
as they wrote it does only work in private windows and to test if it works one has to visit the same page in a private and normal window. Also it is restricted to a unknown (?) list of specific web sites.
So in short: no, I did not test it.
And obviously processing cookie banners automatically requires some kind of scraping technology. Not easy, not reliable. So Im afraid we have to live with that for a while 🤷♂️
