The [tab-close-button](https://searchfox.org/mozilla-central/rev/f9157a03835653cd3ece8d2dc713a782b7e4374e/browser/base/content/tabbrowser-tab.js#40) is not labeled and is missing an interactive role of button, while it is functioning as one. Note: we do not want this control to be keyboard focusable, because keyboard-only user could close the tab via the context menu and we don't want to create an additional tab stop for the navigation as well, but making sure the control is marked up as a button with an accessible name would allow it to be actionable with speech-to-text software, with touch devices, with switch controls in scan mode, and for screen readers via their navigation shortcuts as well.

This directory contains common Python code. The basic rule is that if Python code is cross-module (that's "module" in the Mozilla meaning - as in "module ownership") and is MPL-compatible, it should go here. What should not go here: * Vendored python modules (use third_party/python instead) * Python that is not MPL-compatible (see other-licenses/) * Python that has good reason to remain close to its "owning" (Mozilla) module (e.g. it is only being consumed from there).
