  • Put the install in a known directory (C:\FirefoxBeta for purposes of this example)
  • Do NOT allow it to launch Firefox at the end of the install
2. Disable the automatic updater
  • Open C:\FirefoxBeta\defaults\pref\channel-prefs.js in a text editor
  • Change the line reading pref("", "beta"); to pref("", "foobar");

We are looking for issues with video playback, including but not limited to

  • visible glitches in the UI outside of the video
  • crashes (be sure to submit the crash report)
If you encounter an issue
  • File a bug report
  • Copy your about:support page to a plain text file and attach it to the bug report
  • If you crashed, include a copy of the ID (retrievable from about:crashes) in the bug report
  • Check if the issue reproduces, add that info to the bug report
  • Check if the issue reproduces with hardware acceleration turned back on, add that info to the bug report
  • Check if the issue reproduces with the latest Firefox release, add that info to the bug report
Run this test twice, once on an older GPU driver and again on the latest GPU driver (submit a separate result for each)
