1. An error appears in the Chrome console: DevTools failed to load source map: Could not load content for chrome-extension://ncennffkjdiamlpmcbajkmaiiiddgioo/js/xl-content.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME. See Figure 1.
2. In Settings – Extensions, disable or remove 迅雷下载支持. See Figure 2.
3. The cause might be that 迅雷 is not installed on my operating system, while Chrome installed the 迅雷下载支持 extension due to account extension sync. See Figure 3.
4. Refresh the page, and the error no longer appears in the console. See Figure 4.
