Details

STR:

  1. Open about:certificate
  2. Focus the first (leftmost) tab
  3. Press the LeftArrow key
  4. Press the RightArrow keys to move to the next tabs

AR:
You can't. In the console:

Uncaught TypeError: can't access property "setAttribute", tabs[tabFocus] is undefined
    setAccessibilityEventListeners chrome://global/content/certviewer/components/certificate-tabs-section.js:116
    setAccessibilityEventListeners chrome://global/content/certviewer/components/certificate-tabs-section.js:95

    EventListener.handleEvent* chrome://global/content/certviewer/certviewer.js:12
certificate-tabs-section.js:116:9

ER:
No errors logged in the console, and I should be able to move between the other tabs.

Note that this is more noticeable in RTL because of bug 1603156.
