Simplify Page feature, which when checked in Print Preview window declutters the page for better printing, has been turned off in Firefox 50. Mozilla isn’t going to ship this feature to Firefox users with version 50, three bugs —bug 1306295bug 1306294bug 1306299 — are preventing from rolling this feature to release population. Firefox team wants to fix them and planning to release with version 51. But the Simplify Page feature can be turned on easily in Firefox 50 when released, here is how that can be done.
