Verifying this issue on latest Beta 67.0b3 on Windows 10 x64: - installed the temporary PoC attached (replaced with keydown) and the prevent notification is not bypassed - the xpi.html file provided in comment no longer bypasses the prevent notification - new2.html file is also prevented from installing - new3.html is prevented from installing - new4.html which should cover the web extension install prompt may also be fixed as it no longer displays the message as in the attached screenshot. Now it will look like this https://imgur.com/a/bIetYDK, is this the intended fix? Hopefully, I covered all the testcases that were provided by the reporter. Abdulrahman, could you please take a look again? Just to be sure... Will verify the rest of the OS afterward. Here is the link for the latest Beta that has this patch: http://archive.mozilla.org/pub/firefox/candidates/67.0b3-candidates/build1/
