After most recent Firefox update, black bars now appear across screen in High Contrast Mode. Page displays properly in standard mode and on other browsers.

選擇的解決方法

See:

  • /questions/1279681 The most recent "upgrade" makes unreadable many web pages. How to undo this "upgrade"?

You can set this pref to false on the about:config page.

  • browser.display.permit_backplate = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
