The purpose of this testrun is to vet video playback when hardware acceleration is not available, eg. bug 1255281

Systems

Please use the following systems/configurations for testing:

Set up the test environment

1. Install Firefox
  • Download the latest Beta from https://beta.mozilla.org/ (make sure it's Firefox 46)
  • Run installer and select customize
  • 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("app.update.channel", "beta"); to pref("app.update.channel", "foobar");
  • Save and Close the text file
3. Launch Firefox with a clean profile
  • Run cmd.exe
  • Change directory to the folder where you installed Firefox: cd C:\FirefoxBeta
  • Run firefox.exe: firefox.exe -P -no-remote - This will bring up our profile selector window.
  • Use the "Create Profile" button to create a profile new profile
  • Once the profile is created, select it, and then click "Start Firefox"

Testing

We are looking for issues with video playback, including but not limited to
  • choppy video or dropped frames
  • visible artifacts in the video
  • broken sound
  • hangs or visibly slow performance
  • 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)
  1. Start Firefox with a new profile (see above)
