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 Adobe Acrobat extension installed. It attempts to modify every page causing the HttpWatch recording to be terminated with 'target_closed'.

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

1. Remove the Adobe Acrobat extension if you do not need it
2. Temporarily disable the Adobe Acrobat 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.
