I just noticed that there's a new "Safe Mode" entry under Application Basics in Firefox 42 which wasn't there in Firefox 40.
When you're in normal mode it says "false". When you're in Firefox Safe Mode, it will say "true" and in that case there will be no "Try Safe Mode" option under the "Refresh Firefox..." box.
I updated the article with a new screenshot for fx42 and I added an entry for Safe Mode under Application Basics.
