Testing

Record Graphics Information

1. Start Firefox 43.0a2 if it's not already running
2. Open the about:support page and scroll down to the Graphics section
3. Copy the entire table of information under the Graphics section
4. Paste this information into question 2 of the results form (tip: open form in a different browser so that it's not impacted by testing)
5. Click the Menu button > (?) > About Firefox to check for and install updates, restart Firefox once the update is downloaded
6. Once Firefox restarts, reopen about:support (if it doesn't automatically)
7. Verify that Application Basics displays "44.0a2" as your version
8. Scroll down to the Graphics section and copy the entire table of information under the Graphics section

Sanity Test

Before you begin make sure you've completed the preconditions for this test, recorded your graphics information, and are running Firefox 44.0a2

1. Load the Alexa.com Top-sites by Country page
2. Refer to the Topsites column of the Systems spreadsheet to note which country's topsites you'll need to test
3. Starting with the first country, load the #1 top website
4. Scroll around the page and try to interact with any loaded content (eg. play a video if there is one) until the page finishes loading
5. Open the next topsite in a new tab and repeat the above step (do this for each of the top-10 websites for each of the countries you've been assigned)
6. After you've finished testing each of the websites, restart Firefox and try to restore the session
7. Click each tab and observe the content loading until all pages are loaded
8. Drag any one of the tabs outside of the window so it appears in its own window
9. Drag that tab back to the tab bar of the main window so it rejoins the main window
10. Repeat this with a couple of other tabs
11. Quit Firefox
12. Fill out this form when you've finished testing to record your results.
