This has also been my experience, uBlock origin improved performance on many websites (and also clues me into how many unnecessary connections by analytics and tracking servers are made by so many sites). It is mind boggling to see sometimes 250+ blocked requests on the badge for a news article.
Yeah. I started very aggressively blocking all third party stuff and then I manually whitelist things as needed. Its crazy how many requests some sites make, for stuff that has no impact on the content I actually want.
