Hmm. I guess I'm living the good life with all of the Firefox configuration changes I've made over the years. I have six right-click menu items and four buttons (page back, page forward, reload, and bookmark):

Save Page As, Select All, Take Screenshot, View Page Source, Inspect Accessibility Properties, and Inspect.

And one additional entry for uBlock Origin at the bottom of the menu (Block Element).
