// @description Creates a "Show questions" button for Amazon. Once clicked it opens a new tab of the questions.
// It also creates an "Open Questions tab" context menu entry, which also when clicked opens a new tab of the questions.
// Thanks to u/CaptSkinny, u/lilgeeky, u/Sanpete_in_Utah and u/TTum.
