Turn off the close button in Google Chrome

[Exit]

Sometimes I close the Chrome browser with the X in the upper-right corner of the window, without realizing that I have other tabs open.
Is there a way to prevent the closing process or at least advance a warning?
Maybe through a small GUI that is placed over the X and follows the X when it changes position?
I would be grateful for relevant ideas.

if you accidentally close multiple tabs, just re-open chrome and press ctrl+shift+t to load all tabs that were closed.

Maybe if you add some javascript thry your addressbar or as a bookmarklet

javascript:window.onbeforeunload = confirmExit;function confirmExit() {return "You attempt to leave this page. Are you sure?";}

Not fully tested but seems to work. Maybe other events are better for above trick.

that should work if you put the code into a page saved in your pc, then have chrome load that page every time it opens,

Thank you for these suggestions. Unfortunately, I lack the knowledge to implement this. Would it perhaps be possible to provide a more detailed instruction?

just save the attached html document in your pc somewhere then go into Chrome settings and set it to open specific page on load and put the directory location to your file.

tab close confirm.html

Last I knew there were several Chrome extensions that do just this task, warn before closing all tabs.

 ☹️ Unfortunately it does not work. Although the page appears after browser start, but there is no message when I press the "close" button. All tabs have been closed.

This script is a good start for a solution. 🙂
I will use it.

[junkew]

Changed script in previous post of me a little

• sizing of the overlay window a little better
• added a pixelgetcolor to have same background as titlebar (unsure if there is a function to get actual color)

[Exit]

Now I have found a way to avoid new tabs. The following registry change always opens a new window when clicking on a link.
This solves my real problem.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command]
; old entry
;@="\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" -- \"%1\""
; new entry
@="\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" --new-window \"%1\""
