You may run into a 'target_closed' error while recording with HttpWatch on Chrome or Edge. There are two main causes for this:

1. You visited a restricted page while debugging, e.g. the Chrome Web Store
2. A third party extension such as a password manager has added content to the web page, e.g. a list of password options

The latest versions of HttpWatch now temporarily block extensions adding content like this while recording is active to avoid this problem. However, in some cases it may still occur with a third party extension.

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.
