Maybe Mozilla should remove about:config, so users can't hurt themselves on it. I'm sure the telemetry shows its rarely used, and when it is, it often breaks the browser in ways that are unfixable for the average user. Malware is also able to modify these advanced settings to hijack the browser in nasty ways, and slow down Firefox, and make people switch to Chrome faster. If they don't remove it Firefox is going to continue its user count slide into irrelevance.

(This is in fact sarcasm before you get too eager with that down arrow)
