Unexpected cursor shown inside focused div

I recently noticed a number of places on websites where a cursor would appear in a place where no keyboard input is accepted. I've narrowed it down to this:

Define a div like this: <div tabIndex="1"></div>

Style it like so: div {

 width: 200px;
 height: 100px;
 border: solid 2px red;

} div:focus {

 background-color: lightblue;

}

Click inside the div. It turns blue to show it has focus, but it also shows a cursor at the top-left.

This does not seem to happen when you use <div tabIndex="1" /> and it also doesn't happen in other browsers.

You may have switched on caret browsing. You can toggle caret browsing off/on by pressing F7 (Mac: fn + F7).

  • Settings -> General -> Browsing
    remove checkmark: [ ] "Always use the cursor keys to navigate within pages"

Note that this is a Firefox accessibility feature.

I discovered it doesn't even need to support focus. Just the click on a basic div shows the same.

<html>

 <head>
   <style>
     div {
       width: 200px;
       height: 100px;
       border: solid 2px red;
       padding: 10px;
     }
   </style>
   <title>Unexpected cursor in clicked div</title>
 </head>
 <body>
   <h1>Unexpected cursor in clicked div</h1>
   <ul>
     <li>Click inside the rectangle below.</li>
     <li>
       Expected: Nothing should change.
     </li>
     <li>Actual: A cursor appears at the top-left of the box.</li>
   </ul>
   <div></div>
 </body>

</html>

Ah, there you go. That's exactly what it was. I'm not sure how I had turned that on.

Thanks for the speedy explanation!
