Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

  1. Activate "Strict" protection in Firefox Privacy settings
  2. Go to a website which has Event tracking from Google Tag Manager (eg. https://wingtra.com/)
  3. Click on an item in the big menu navigation

Actual results:

--> Page load is delayed, nothing happens during a few seconds, then the page load starts

Expected results:

--> When "Strict" is deactivated in privacy settings, the page loads immediately, without delay

Google Tag Manager and Event tracking on links is a widespread tool on many websites. Users with "Tracking protection" on "Strict" settings in Firefox will not understand why some websites/links have this delay and will think the website doesn't work properly. Although the issue is related to their privacy settings
