Today, I had to disable uBlock Origin to be able to post. I had to allow scripts from several domains to be able to post and search the forum. It wasn't exactly obvious what I needed, and for the forum search you have to allow cloudflare before you can allow the search provider.
I can't recall a time I've had to disable uBlock before I could interact with a webform either.
Is there a list of minimum scripting and ad domains?
How are ad networks' scripts/ads related to be able to post?
Reading the forum works fine with no scripting allowed, and ad blocking turned on. I block scripts and malware to prevent malvertising and malware infections.
