Here is how I set up the proxy But as a reminder this code works, the issue is if you try connecting to a proxy server that isn't available, the browser just shuts down and my extensions code is not longer run with the page. Is there a way to catch this error? Any thoughts are greatly appreciated. The weird issue is my extensions code does not run on this page.Īm I missing a specific "matches" in the "content_scripts" in the manifest file thats special to error pages? (even though the url of the error page is the url for the page I am trying to visit and the extension code runs on if there is a working proxy/connection) I have been in search of a way to detect this failure to connect so I can restore the connection either with a different proxy or just the normal ip without a proxy. I currently am developing a chrome extension that allows the user to set up a proxy, however my issue is if the proxy failed to load, chrome returns with net::ERR_PROXY_CONNECTION_FAILED in the console and a html page that says "Unable to connect to the proxy server".
