Chrome 80: Pause Script Execution (F8) Does Not Work When DevTools Is Not Focused

Image
Answer : Until it is fixed, you can use the following in your app: document.addEventListener('keydown', function (e) { if (e.keyCode == 119) { // F8 debugger; } }, { capture: true }); It's a bug in Chrome, I found the bugreport here: https://bugs.chromium.org/p/chromium/issues/detail?id=1049910&q=f8&can=2 WORKAROUND You can use option Break on -> subtree modifications It helps me to stop script execution instead of using f8 functionality. Steps: 1. Turn on 'Break on' for element you need to debug 2. Make some changes (hover or open drop down list as in my situation) 3. Browser will pause script execution

Alternatively if you want to search and replace in the HTML you could Right Click → Edit as HTML the <body> in the DevTools Elements Panel select all the text with Ctrl + a , paste into your favourite editor, make the change there and paste it back. ***Taken from this page at labnol.org**** While you are on the web page, press Ctrl+Shift+J on Windows or Cmd+Opt+J on Mac to open the Console window inside Chrome Developer tools.

"CAUTION: Provisional Headers Are Shown" In Chrome Debugger

Image
Answer : The resource could be being blocked by an extension (AdBlock in my case). The message is there because the request to retrieve that resource was never made, so the headers being shown are not the real thing. As explained in the issue you referenced, the real headers are updated when the server responds, but there is no response if the request was blocked. The way I found about the extension that was blocking my resource was through the net-internals tool in Chrome: For Latest Versions of chrome Type chrome://net-export/ in the address bar and hit enter. Start Recording. And save Recording file to local. Open the page that is showing problems. Go back to net-internals You can view Recorded Log file Here https://netlog-viewer.appspot.com/#import click on events (###) and use the textfield to find the event related to your resource (use parts of the URL). Finally, click on the event and see if the info shown tells you something. For Older Versions of chro...

Automatically Open Chrome Developer Tools When New Tab/new Window Is Opened

Image
Answer : On opening the developer tools, with the developer tools window in focus, press F1 . This will open a settings page. Check the "Auto-open DevTools for popups". This worked for me. UPDATE 2: See this answer . - 2019-11-05 You can also now have it auto-open Developer Tools in Pop-ups if they were open where you opened them from. For example, if you do not have Dev Tools open and you get a popup, it won't open with Dev Tools. But if you Have Dev Tools Open and then you click something, the popup will have Dev-Tools Automatically opened. UPDATE: Time has changed, you can now use --auto-open-devtools-for-tabs as in this answer – Wouter Huysentruit May 18 at 11:08 OP: I played around with the startup string for Chrome on execute, but couldn't get it to persist to new tabs. I also thought about a defined PATH method that you could invoke from prompt. This is possible with the SendKeys command, but again, only on a new instance. And DevTools do...
