If the Marker.io button isn’t showing on your website in Comet Browser, it’s likely being blocked by the browser’s built-in ad blocker.
How to Fix It
You have two options:
Option 1: Turn Off Ad Blocking in Comet
Open Comet Browser Settings.
Go to Privacy and Security.
Find the Ad Block section.
Turn the ad blocker off.
Refresh your website — the Marker.io button should now appear.
Option 2: Allow Marker.io on Your Site
Open Comet Browser Settings.
Go to Privacy and Security → Ad Block.
Look for Allow ads on these sites (or similar wording).
Add your website’s domain (the one where Marker.io is installed).
Save the change and refresh your page.
That’s it! Your Marker.io widget should now appear correctly in Comet Browser.
