I saw an issue that referenced the console, so just for kicks I opened my browser console. And discovered an error!
DevTools failed to load source map: Could not load content for chrome-extension://gighmmpiobklfepjocnamgkkbiglidom/browser-polyfill.js.map: System error: net::ERR_FILE_NOT_FOUND
Based on that discussion, it's... not a problem? user1849962 and Marco Mazzon's responses seems to have the best explanations; it's not clear to me that adding a source map (or pretending to) is necessary, given that there is no functionality issue, and it only appears for certain extensions, which is likely a small portion of users. But I figured I should at least mention it here, since it is an error message.
