Broken and breaks all websites
by Rat Gamez, 2025-01-22

Version 12.1.1 is causing web pages not to load. I have cleared cache and cookies, no change. Everything will work if I disable NoScript. Do you have a repository of past versions of NoScript. I would like to downgrade until a fix can be provided.
