3. Browser Settings

Once you have the latest supported browser versions, you may easily start the test. However, in a rare case you may face difficulty in starting the test, due to the pop-up blocker setting of your browser. Here is what you can do to fix this:
  1. Use the “allow once/always” pop-ups function from your browser settings to allow test window to open
  2. Optionally, you may disable the pop-up blocker for the duration of the test. Here is how you can do it:
    1. For Mozilla Firefox on Windows: Click the menu button    and select Settings -> Select the Privacy & Security panel -> Go down to the Permissions section -> Uncheck the box next to Block pop-up windows to disable the pop-up blocker altogether.
    2. For Google Chrome: Go to ‘chrome: //settings/’ --> Click on 'Show advanced settings' (at the end of the page). Under 'Privacy and Security', click on Settings' > Privacy and security > site settings > Pop ups and Redirect’s > by clicking on > Sites can send pop-ups and use redirects, you’re allowing the site pop up’s.
    3. Microsoft Edge:  Go to 'edge: //settings/content/popups' go to settings > Cookie’s and site permissions > Pop Ups and Redirect’s disable 'Block'.
After performing the above steps, please restart the browser.

 4. Things to remember

  1. Browser Cache Settings: 

  1.  It is always advisable to clear browser cache/cookies before starting any Mettl tests. For most browsers, pressing “CTRL+SHIFT+DELETE” and selecting Clear Cache (for Firefox and Chrome) helps you clear the cookies.
  1. In case you still face any issue in loading the test, shut down the system directly using the power button and then clear the cache again.

  1. System Updates:

    1. Mercer | Mettl also recommends to disabling the security patches, updates of the anti-virus definitions and/or application updates (manually) during the test to avoid any interference while taking the test.  You can disable automatic system updates for the duration of the test as they may lead to heavy downloads during the test and auto-system restart will hamper your test progress.
    2. To disable System Auto-updates, follow the below steps:
      1. For Windows, Go to ‘Start’ -> ‘Run’ -> Type Services.msc’ and then stop ‘Automatic Updates’ service.
      2. In case you get a prompt that 'Ports 1987 and 1988 have been blocked, please contact your network administrator to assist you with system permissions.
