If you don't care about extensions, try some of those "DE default" browsers that never seem to be actual defaults. The ones like GNOME Web, Falkon, Konqueror, Midori (it was the default on one XFCE system once).
Matches contain sulfur and phosphorus, burning them releases oxides into the air. Sulfur trioxide reacts with water to produce sulfuric acid. You must have sensitive detection for hazardous chemicals.
I would travel back in time and make Acorn RISC OS go mainstream. It's a light OS with a full desktop environment, capable of playing video and rendering anti-aliased fonts, that boots all from ROM and runs on an 8MHz ARM CPU and 512 KB RAM.
I said "go back in time" because I'm not sure how advanced it is compared to modern systems, it's single-user only and has cooperative multitasking, instead of preemptive.
Now that is dumb, way dumber than "blacklist/whitelist", "master/slave controllers". You could make it gender-neutral without even changing the acronym!
Man in the middle --> Monkey in the middle, Moron in the middle, Maggot in the middle, etc
If you want to be bureaucratic, you could just say "Attacker in the middle".
The new term is more obscure and less specific, since it does not have the "middle" component.
"X in the middle" = there's something between two points, in the middle of them.
Any etymology derived from an acronym is probably false.
"News" - supposedly from "Notable Events, Weather, Sports" or "North, East, West, South" but that's false, it's actually the plural of "new" and it means "new things" or "recent events".
"Posh" - supposedly from "Port Out, Starboard Home", which refers to a rich person on a ship who always wants to be on the shady side, but that's false, the true origin is unknown but it probably comes from the Romani word "posh" which means half.
"Fuck" - supposedly from "Fornicating Under Consent of King" or "For Unlawful Carnal Knowledge", but that's false, it's actually from Proto-Germanic "fukkōną", which means "to bang, hit, have sex".
"Shit" - supposedly from "Ship High In Transit", which was supposedly a sign posted on ships that transported manure, but that's false, it's actually from Proto-Germanic "skītan", which means "to defecate, excrete".
I can't tell if you're joking or not, so I just infodumped as a preemptive measure.
