Visual comparison of same page

Web Performance Discuss Test Results

I’d like to visually compare the same page loading, but on one of the pages to block a third party script from loading. I’m trying to highlight any difference with the script present and not.

I can block a script from loading with an advanced test under ‘block’. But how can I use visual compare while blocking a script from one?

If you click on “Test History” you can select any arbitrary tests to compare. Just run the 2 configurations separately and then compare them after the fact (works best of you fill in the “Label” field in the advanced settings so they are easy to tell apart).
