This just won't work for me. I put "about:addons-memory" (without the quotes, copied so I didn't typo it) in the URL bar and it just reloads the page I'm on. I turned off searching from the URL bar to keep it from doing a search on the phrase instead of loading the add-on, but that still didn't work. FF 56.03, Windows 7, FWIW.
If someone has advice that helps me get it working, I'll revise the review.
