I’ve been trying to test the differences between HTTP 1.1 and HTTP 2.0 but have been unable to get the firefoxPref script option to work.
I’ve been using the following script
an example of the test results are available here: WebPageTest Test - Running web page performance and optimization tests...
Inspecting the requests show the H2 pseudo-header fields
and the User-Agent has also not been changed.
Am I missing something?
Thanks
