A suggestion was made that I use Safe Mode to troubleshoot a problem.
It did not help because Safe mode did not ignore the User Setting override that chose Desktop View mode on a mobile device.
Shouldn’t the Safe Mode bypass such preferences settings?
HEY! Where can I find the feature that recognizes key phrases (like Safe Mode ) and automatically links them!?!?! I want that!!! 
The feature is called auto-replace watched words.
Close, but not quite! But I managed to find it.(Whilst dancing around because I was so excited that I was in danger of piddling myself!)
Linkify! [No, @Moin was right. The Linkify function was folded into Watched Words → Link,]
You don’t need the linkify component anymore, it’s been built-in:
admin → customize → watched words → link
Thanks! Could you admin-hack the posting linked above and insert a [Now built-in as “Watched Words”] notice at top? And add “Watched Words” to this site’s list of Watched Words? Amazing that the first thing linked wasn’t the feature itself!
No, it shouldn’t. The safe mode feature is about removing plugins and themes, and not user settings.
I’ve been a professionally beta testing software (from application suites to BIOS) for more than a quarter century. User preferences are often a sources user issues. Many safe modes fallback to defaults.
Since there are already 3 sets of options when entering Safe Mode. adding an option to disable loading end-user customizations seems like a no-brainer:
If that’s something you are keen to work on and contribute as a pull request we can consider merging it, provided the PR is in good shape.
Forking it myself would certainly be the most the immediate option… but probably also the most disastrous.
Let’s see if the idea piques the interest of someone at least mildly qualified to code it. (Which ain’t me.)
