Alt-Control-R should switch between normal rendering and Reader mode. All the documentation available including the "tooltip" that pops up when I hover my mouse over the Reader icon agrees.
And yet, in the File menu, there is an item "Restart (Developer)" with the same shortcut. And when I in fact press this key combo, this is what happens: Firefox restarts. I have no use for this, while the Reader shortcut is moderately useful. I haven't seen the Restart menu item before, I think it appeared with the last stable Firefox upgrade (60.7.2). Is this a problem with upstream or the Gentoo package? Can it be worked around, without leaving _all_ developer features out? -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
