I reported the same issue about two weeks ago, however back then it happened even when using a new clean Orion Profile. The latest Orion RC version, 0.99.131.3-rc, fixed the underlying issue, except now the poor performance only happens when I have the extension Consent-O-Matic enabled, for either Firefox or Chrome.
As before, the initial landing on https://soranews24.com is fine, however scroll down fast enough and loading begins to crawl and even causes Orion to freeze up for a few seconds.
I installed Consent-O-Matic for Safari (Safari version 18.3.1 (20620.2.4.11.6)) from the Apple App Store, and confirmed the issue does not happen in Safari.
Expected: No poor performance when loading https://soranews24.com when using Consent-O-Matic extension.
Version 0.99.131.3-rc
