My Firefox web console has suddenly taken to showing an autocompleted list of suggestions as I type. This makes things difficult — for instance, I have a variable called "a". I want to see the value of "a" so I type "a" and hit return. What happens is that the list pops up and "addEventListener" is selected. Now "addEventListener" is sitting on my console instead of the "a" I typed. I must therefore type "a", hit escape and then hit return. This makes it so I frequently have to hit escape. In the settings I only found a CSS autocomplete feature that I can toggle. In the about:config I found "devtools.editor.autocomplete" and I changed it to "false" but I'm still seeing the same behavior. How do I turn off autocomplete in the web console?
