Why isn’t incomplete test data mentioned on the “blame list”? Beats me. The “crash” turned out to be a general issue with the testing framework, anything that prevents the browser from being closed will cause the test to be ignored. The other two tests (on Mac OS X and Fedora Linux) “crashed” and weren’t considered in the results at all.

The good news: they are not entirely wrong. Can the numbers displayed on the blame list be trusted at all? One of the replies to my previous blog post prompted me to take a closer look at the raw data from the add-on performance measurements. Adblock Plus and (a little) more How reliable are Mozilla's performance measurements?
