Set up the test environment

1. Install Firefox

• Download the latest Beta from https://aurora.mozilla.org/
• 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"

Test

1. Start with a new profile (see above), load the about:config page and verify the value of layers.d3d11.disable-warp:

• Windows 8 and above should be false by default
• Windows 7 and below should be true by default

2. Resize the window so it's at least 1024x768

3. Go to huffingtonpost.com, scroll up and down for ~15 seconds, resize the window to a random size

4. Open another tab and go to flickr.com, scroll up and down for ~15 seconds, resize the window to a random size

5. Switch back and forth between the two tabs three times

6. In huffingtonpost.com tab, go to youtube.com and play this video, this video, and some other random video for 15 seconds

• Note: If a video plays with Flash find another video to test. To check, right mouse click on the video and choose “Stats for nerds”. The video is valid if the mime type is video/mp4 or video/webm.

7. Go to Google Maps, explore any location with Street View and Image View, resize the window to a random size

8. Update your graphics driver to the latest available version

• Note: don't restart Firefox or your computer if it can be avoided. If Firefox crashes, report the crash, restart Firefox and continue on to step 9.

9. Repeat the test from step 3 through 7.

• Note: if Firefox crashes, report the crash, restart Firefox and repeat steps 3 through 7.

10. Open the about:support page and scroll down to the Graphics section, if there are any errors reported include this information when you submit the form below.
