I recently added Google Tag Manager for a customer and in experimenting I added to my company website. Now in FireFox I am getting a preview pane at the bottom of the page. In Chrome this can be turned off, but I couldn’t find how to do in Firefox till I found the following article.
The basics for this are:
- Log in to Google Tag Manager.
- Go to your site dashboard (Workspace < Overview).
- Click on the option that says Leave Preview Mode.
I hope this helps someone else out there.
