I didn't see any Ctrl+1-9 options there, but I cleared everything other than Copy/Paste anyway and it's still behaving the same; with Ctrl+1-9 still changing tabs.

Zero, I don't think that there is any native way to disable the ctrl+# hotkeys at present, unfortunately.

One possible workaround is to play the game in its own window where it is the only tab? You can open a new window from the File menu, or via the ctrl+N hotkey. Or if you launch the site from a bookmark, right-click it and select "Open in New Window".

With only one tab the ctrl+# hotkeys should do nothing, so thought this might be a good enough workaround?

Yeah, you're right, seems I'll just have to play in multiple windows for now. Thanks for mentioning this, though, I didn't really think of that.

I had the exact same issue while playing browser games in Firefox. The Ctrl + Tab switching is super annoying when you accidentally press Ctrl and suddenly your game tab changes. Unfortunately, Firefox doesn’t have a built-in option to completely disable that shortcut.

What worked for me was going into about:config and changing the tab switching behavior. You can search for browser.ctrlTab.recentlyUsedOrder and set it to false. It doesn’t fully disable Ctrl + Tab, but it makes it less disruptive.

Another option is using an add-on that lets you customize or disable shortcuts. Some keyboard shortcut manager extensions can override Ctrl combinations. If one extension shows as “corrupted,” try reinstalling it or testing a different one — sometimes profile issues cause that error.
