How Firefox Devs Write Unit Tests for the Private Browsing Indicator

Firefox's private browsing indicator — comprising an icon and a label — appears in two different locations depending on whether horizontal or vertical tabs are enabled. In horizontal tab mode, the indicator sits in the TabsToolbar and displays both the icon and its label, while in vertical tab mode it moves to the Navbar and shows only the icon. Developers writing unit tests for this behavior first grep the codebase to locate the relevant CSS and XHTML markup files controlling the indicator's visibility. The CSS rules confirm that the indicator is hidden entirely in non-private windows, repositioned for horizontal tabs, and label-stripped for vertical tabs. Unit tests are structured using add_task, BrowserTestUtils.openNewBrowserWindow with the private flag, and BrowserTestUtils.isVisible to verify correct rendering in both tab configurations.

Developer Builds Angular Component Library With Accessibility Baked In From the Start

A developer with ten years of Angular experience has built a component library designed to treat accessibility as a core requirement rather than an afterthought. The project was motivated by a recurring pattern across teams where keyboard support, ARIA attributes, and screen-reader compatibility were consistently deprioritized in favor of meeting deadlines. Unlike most existing libraries that rely on automated tools like AXE for accessibility checks, this library requires every component to pass manual keyboard and screen-reader testing before it ships. Key features include proper focus management in dialogs and drawers, live regions for dynamic announcements, and keyboard-navigable data visualizations backed by hidden data tables for screen readers. The author argues that accessibility gaps are a systemic design problem, not a matter of individual effort, and that the only fix is changing what ships by default.
