_Originally created by @bertagaz on [#10116 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/10116)_ I’ve seen it failing quite often, on my test machine and on Lizard. It fails at the `And I click the blocked video icon` step, and the screenshot shows that the browser prints a “Connection timeout” to the `https://webm.html5.org/test.webm` webpage. Maybe providing such a webpage locally would help to prevent network troubles, with the same trick used for the “The Unsafe Browser can access the LAN” scenario?
