Description

2 years ago
There are several things that need to be addressed for it to be accessible:

* It must be included in the tab order for the new tab. Since it is the first (topmost/left in LTR) control on the page it should likely be the first one that the user tabs to.

* Currently the icon is just a DIV. Semantically though, it is a button that triggers the dialog so it must be BUTTON in the markup.

* The button does not have a label either. It must be added and be internationalized (e.g. alt text).

* It should also implement "aria-haspopup" to indicate that it has a popup context [1].

Hi Yura, the patch

* referenced https://www.nczonline.net/blog/2013/04/01/making-accessible-icon-buttons/ and use <input type="image"> which should been treat as the <button> in screen reader
* move fox icon as the first body element so it will be first selected
* add localizationable alt text and "aria-haspopup"
* allow navigate with tab and use space to toggle the onboarding overlay


To test onboarding, you can create a new profile and the onboarding fox icon will be shown.

Not sure if this change is required for the bug.

From what I can tell, input type image is used for Submit buttons only. I think this is somewhat incorrect to use it since we are adding all the form action related overhead. We are not actually making a form action when the button is pressed. I would rather use a plain input type button or better (more styleable) button element.

I think leaving this will indicate it's clickable better, do you have other considerations?

This change makes the icon unclickable because it  is covered by newtab-vertical-margin on newtab page. We may need to do something like adjusting z-index or pointer-events.

Thanks for catching that! I was use `input type="image"`, which has point curor hover by default, but I forgot to add it back with `button`

More in-depth review, I added a simpler solution that hopefully does the same thing. Also we can just use title and get a tooltip for free. aria-label should be our last resource.

to be consistent with customize icon, lets set it to 101

all in all, consistent with customize gear icon we can do this:
```
#onboarding-overlay-icon {
  position: absolute;
  top: 30px;
  offset-inline-start: 30px;
  z-index: 101;
  background-image: -moz-image-rect(url(resource://onboarding/img/overlay-icon.svg), 0, 36, 36, 0);

  width: 36px;
  background-repeat: no-repeat;
  background-position: center;
  background-color: transparent;
  border: none;
  outline: 0;
}

/* to remove dotted firefox border */
#onboarding-overlay-icon::-moz-focus-inner {
  border: 0;
}

/* nice overlay for hover and focus that is consistent with the gear icon */

  background-color: #FFFFFF;

We can do this without an img inside a button:
```
let icon = this._window.document.createElement("button");
    icon.id = "onboarding-overlay-icon";
    let tooltip = this._bundle.formatStringFromName("onboarding.overlay-icon-tool-tip", [BRAND_SHORT_NAME], 1);
    icon.setAttribute("aria-haspopup", true);
    icon.title = tooltip;
    return icon;

Oh and another nit: can we rename the word 'icon' in selectors everywhere to 'button' since that's what it actually is.

If went for `background-image`, we wouldn't see the little fox image in the high-contrast mode.
The bug 1377439 will switch from <img> to <button> for this onboarding fox icon button.

The bug 1377439 could do this btw.

After discussing with :gasolin, since the bug 1377439 is having higher priority, we are doing it first.
Let the bug 1377439 handle this onboarding fox icon button in the high-contrast mode and let this bug handle the rest of work such as button label and tooltip etc.
Set the dependency.

Thanks for update the patch, it works great! 

Though while hover on the icon, the visual rectangle is not needed and the visible `tooltip` looks not right since we already show the message bubble to user.

Let's let verdi decide.

I agree, for mouse users we shouldn't show the rectangle on hover or click and the tooltip is not needed.

Just a drive-by:
There is a `openTab` helper function in the onboarding's head.js.
So the above 2 lines could be simplified into `let tab = await openTab(ABOUT_HOME_URL);`

p.s1: Inside the `openTab`, it would make sure the browser is really loaded then proceed. That could avoid some intermittent case.
p.s2: Could use `await reloadTab(tab)` if needed to reload a tab.

Abe, 

First make sure the behavior is the same for mouse user, ex there should not have a highlight when hover the icon with mouse


Then, click the search bar and use `tab` key to navigate,

* the fox icon should be the first item in content page
* There will be a highlight around the icon when navigating with tab key
* while highlighted, can use `space` key to open the onboarding overlay dialog
