Prevent the cancellation of important shortcut keys in the browser by web pages.

nafumofu

The Vivaldi browser has a bug that causes it to accept cancellation of important shortcut keys such as Ctrl+W, Ctrl+Tab by a web page's JavaScript.
This user script partially resolves this bug.

Installation

install Tampermonkey or Violentmonkey from the Chrome Web Store
install the user script from this link.

I reported this bug in 2018 and unfortunately it still has not been fixed.

Thank you.

In Chromium browsers it is not necessary to install an extension.

Click on the “Install this script” button, apply “Save link as” from the context menu and save the file “preventDefault Patch.user.js” in a safe folder without deleting it.

Drag it to Extensions page with Developer mode on:

PS:

The only drawback is that if there is an update, you have to do the procedure again.

Direct installation does not seem to work because the window object of the page cannot be accessed due to differences in the context of the script.

It is good that you clarified it, since there are users who are reluctant to install the Tampermonkey (MV3) or Violentmonkey (MV2) extensions, and therefore there are times when it is essential.

So, it is smarter to install the extension and put it in there ➤ never any peoblems.
