Firefox DevTools MCP (firefox-devtools-mcp) 0.10.2 is out on [npm](https://www.npmjs.com/package/@mozilla/firefox-devtools-mcp).

**New tools:**

- `press_key` — sends a single key, optionally with modifiers, to a snapshot element or the focused element (Return, Escape, Tab, arrows, ctrl+shift+t, …).
- `type_text` — types text key by key into the focused element, with an optional key to press afterwards.
- `set_network_cache` — bypass or restore the HTTP cache, for the selected tab or browser-wide. Useful before a performance measurement or when verifying a change a cached asset would otherwise hide.

**Other changes:**

- `navigate_page` and `new_page` take an optional `wait` argument (none, interactive, complete), so an agent can wait for the load event before deciding a page is done.
- Windows: per-user Firefox installs are now detected, instead of failing with “unable to find binary in default location”.
- aarch64 Linux: geckodriver is now resolved on all platforms, fixing “Unable to obtain browser driver” when a native geckodriver is on PATH.
- Several Windows path fixes for --output-file, --log-file and saveTo.
- New generated reference page documenting every tool and its parameters: docs/tools.md ([firefox-devtools-mcp/docs/tools.md at main · mozilla/firefox-devtools-mcp · GitHub](https://github.com/mozilla/firefox-devtools-mcp/blob/main/docs/tools.md))

For internal Firefox development, swap `firefox-devtools-mcp` with `firefox-devtools-mcp-moz` in order to benefit from additional tools, such as chrome-privileged script execution.
