You may run into a 'target_closed' error while recording with HttpWatch on Chrome or Edge. The most likely cause of this error is that you have the iCloud Passwords or Adobe Acrobat extension installed and enabled. These extensions attempt to modify the current page causing the HttpWatch recording to be terminated with 'target_closed'. Other third party extensions that also access the web page may trigger the same error.

There are several possible work-arounds that can be applied by locating the third party extension in the chrome://extensions page

1. Remove the extension if you do not need it
2. Temporarily disable the extension by toggling the switch next to it
3. Go to the Details page of the extension and change the Site Access to 'On Click'. This will prevent the extension becoming active until you click on its toolbar button.
