Hi,
Can someone have a look at this updated selenium test [0], I don't have an acitve Selenium setup.
Regarding Selenium : currently these tests are not run on our Jenkins server. Would it be difficult to set up a Selenium server with a few recent browsers installed? If we can automate tests for a series of browsers, we might catch problems with CSP before a user files a bugreport.
