Created attachment 8838949 [details] network_monitor_chromium.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36 OPR/39.0.2256.43 Steps to reproduce: Summary ----------- I performed a simple test in both Firefox and Chromium to see how network requests blocked by uMatrix were displayed in the network monitor component of the developer tools of both browsers. Browser and add-on information ------------------------------------ Firefox: Nightly 54.0a1 (2017-02-19) (64-bit) Chromium: 56.0.2924.76 (64-bit) uMatrix: 0.9.3.6 (my uMatrix configuration is to block everything by default) Steps ------- 1. I launched Firefox and then opened the Network Monitor with the filter set to 'All'. 2. I then browsed to 'news.com.au' in Firefox and observed the output of the network monitor. 3. I performed the same steps in Chromium. Actual results: 1. Firefox received a 301 redirect after loading 'news.com.au' and proceeded to load 'www.news.com.au'. 2. uMatrix in Firefox correctly blocked everything other than these two requests, see umatrix_firefox.png. 3. The Firefox network inspector displayed these two requests but not the requests that were blocked by uMatrix, see network_monitor_firefox.png 4. Chromium received a 301 redirect after loading 'news.com.au' and proceeded to load 'www.news.com.au'. 5. uMatrix in Chromium correctly blocked everything other than these two requests, see umatrix_chromium.png. 6. The Chromium network inspector displayed these two requests along with the requests blocked by uMatrix, see network_monitor_chromium.png. The blocked requests appeared in red and showed the error 'ERR_BLOCKED_BY_CLIENT'. Expected results: It would be very helpful if Firefox could display blocked network requests in its network monitor, in a similar fashion to Chromium.
