Add a switchers chapter and fix drift found on a second manual pass

Add "Coming From Mac or Windows" as chapter 3: a translation layer for
Cmd/Win instincts rather than a feature tour.

Fill the remaining coverage gaps: fcitx5 input methods, laptop speaker
tuning, touchpad haptics, crash capture in the toggle table, the
installable font list, and the ChatGPT Desktop and Grok Bot entries.

Correct claims that drifted from the source: the network and bluetooth
bar icons no longer launch nmtui/bluetoothctl, monitor scaling steps
rather than cycles, and the display widget's scroll steps brightness.

+# Browsers
+
+Omarchy ships with [Chromium](https://www.chromium.org/) as the default browser. It's the plain open-source build, themed to match the rest of your system, and it's what `Super + Shift + Return` opens and what every [web app](25-web-apps.md) runs inside.
+
+If Chromium isn't your taste, you're not stuck with it. Under _Install > Browser_ in the Omarchy menu you'll find Chrome, Edge, Brave, Brave Origin, Firefox, and [Zen](https://zen-browser.app/). Pick one and Omarchy installs it, sets up its policy directory, and applies your current theme to it.
+
+## Making one the default
+
+Installing a browser doesn't promote it. Once it's on the machine, go to _Setup > Defaults > Browser_ and pick it — the menu only lists browsers you actually have installed, and marks the current default with a check.
+
+From the terminal it's:
+
+```bash
+omarchy default browser firefox
+```
+
+Run it with no argument and it tells you the current default. This sets the XDG handler, so it's not just Omarchy's hotkeys that follow along — anything that opens a link, from a chat app to a terminal command, goes to the browser you picked.
+
+## Copy URL and Download Video
+
+The Chromium-family browsers (Chromium itself, Chrome, Edge, and Brave) come with two Omarchy extensions that reach out of the browser and into the rest of your system.
+
+**Copy URL** puts the current tab's address on your clipboard with `Alt + Shift + L`. That's faster than clicking into the address bar and copying, and because it goes through the system clipboard rather than the browser's, you get an Omarchy notification confirming it and the URL is immediately available in [clipboard history](08-unified-clipboard-history.md) and every other app. There's a toolbar button too, if you prefer clicking.
+
+**Download Video** grabs the video playing on the page you're looking at with `Alt + Shift + D`. It hands the URL to [yt-dlp](https://github.com/yt-dlp/yt-dlp), so it works on far more than YouTube, and the download lands in `~/Videos`. Progress shows up in the same on-screen display that volume and brightness use, updating in place rather than stacking up notifications. Set `OMARCHY_YTDLP_DIR` if you'd rather the files went somewhere else — see the [FAQ](47-faq.md) for where to put environment variables.
+
+Both extensions talk to Omarchy through a small native messaging host, which gets installed for you along with the browser. That's the piece that lets a web page's video end up in your home directory and a URL end up in your clipboard manager, which a normal extension can't do on its own.
+
+These are Chromium-family only. Firefox and Zen don't get them.
+
+## Firefox and Zen
+
+Firefox and Zen are a different family, so they get different treatment: Omarchy installs a policies file for sensible defaults and switches them into native Wayland mode, which you want for fractional scaling and smooth trackpad scrolling.
+
+They don't get the Chromium extensions above, and they're not themed by Omarchy, so those parts of the experience are yours to set up.
+
+## Removing one again
+
+Anything you installed here can be taken back off under _Remove > Browser_. Chromium isn't in that list — it's part of the base system.
