ensured footer was pinned to bottom of page for new-ish billboard.html & room_scroll.html pages; introduced mobile landscape layout, incl. leftward 'navbar', rightward 'footer'; ensured z-index primacy of #id_kit_btn, which would here appear behind the kit bar when open; other fixes introduced by problems stemming largely from new landscape styling

 All tools require a `tabId` except `firefox_create_window` and `firefox_diagnose`.
 
 ### If tools aren't available in a session
-MCP servers load at session startup only. **Start a new Claude Code session** to pick them up.
+MCP servers load at session startup only. **Start a new Claude Code conversation** (hit "+" in the sidebar) — no need to reboot VSCode, just open a fresh chat. Always call `firefox_diagnose` first to confirm the connection is live.
+
+### Correct startup sequence
+1. Firefox open with Claudezilla extension active (native host must be running)
+2. Open a new Claude Code conversation → tools appear as `mcp__claudezilla__firefox_*`
+3. Call `firefox_diagnose` to confirm before depending on any tool
 
 ### Setup (already done — for reference)
 The native messaging host requires a `.bat` wrapper on Windows (Firefox can't execute `.js` directly):
 - Wrapper: `E:\ClaudeLibrary\claudezilla\host\claudezilla.bat` — contains `@echo off` / `node "%~dp0index.js" %*`
 - Manifest: `C:\Users\adamc\AppData\Roaming\claudezilla\claudezilla.json` — points to the `.bat` file
 - Registry: `HKCU\SOFTWARE\Mozilla\NativeMessagingHosts\claudezilla` → manifest path
-- MCP server: `~/.claude/settings.json` and `~/.claude/mcp.json` — both register `node E:/ClaudeLibrary/claudezilla/mcp/server.js`
+- MCP server: registered in `~/.claude.json` (NOT `~/.claude/settings.json` or `~/.claude/mcp.json`) — use the CLI to register:
+  ```
+  claude mcp add --scope user claudezilla "D:/Program Files/nodejs/node.exe" "E:/ClaudeLibrary/claudezilla/mcp/server.js"
+  ```
 - Permission: `mcp__claudezilla__*` in `~/.claude/settings.json` `permissions.allow`
 
+**Config file gotcha:** The Claude Code CLI and VSCode extension read user-level MCP servers from `~/.claude.json` (home dir, single file) — NOT from `~/.claude/settings.json` or `~/.claude/mcp.json`. Always use `claude mcp add --scope user` to register; never hand-edit. Verify registration with `claude mcp list`.
+
+**BOM gotcha:** PowerShell writes JSON files with a UTF-8 BOM, which causes `JSON.parse` to throw. Never use PowerShell `Set-Content` to write any Claude config JSON — use the Write tool or the CLI instead.
+
 Native host: `E:\ClaudeLibrary\claudezilla\host\`. Extension: `claudezilla@boot.industries`.
