Mozilla announced Firefox DevTools MCP 0.10.6 on October 16, 2026, and confirmed npm availability. The update adds PDF export, fixes browser profile reuse and revises tab targeting for coding agents, according to Mozilla. Sources: Mozilla

Mozilla says print_page saves the current page as a PDF using print CSS, with options for horizontal orientation and backgrounds. The company highlights print-style checks; potential applications include inspecting print layouts for invoices and reports. Sources: Mozilla

Mozilla says --profile-path now directly reuses server-created browser profiles carrying a.firefox-devtools-mcp marker. According to the announcement, unmarked paths still receive a firefox_devtools_mcp_profile subfolder, so direct reuse does not apply to every existing Firefox profile. Sources: Mozilla

Mozilla says tab enumeration now uses WebDriver BiDi, the bidirectional browser automation protocol, without foregrounding every tab. According to Mozilla, selection and closure target entries from the last returned tab list despite intervening changes. Mozilla says unloaded restored tabs are omitted. Titles unavailable within one second appear as (unknown). Sources: Mozilla

The repository lists Node.js 20.19.0 or newer and locally installed Firefox 100 or newer as minimum requirements. It names Claude Code, Claude Desktop, Cursor and Cline, and provides Codex setup instructions. These documented requirements and client instructions do not establish tested support for every feature in 0.10.6. Sources: Mozilla

Why it matters

Mozilla’s changes could help coding agents check printable output and reuse browser state. PDF export alone does not establish that pagination, typography or document contents are correct.

Firefox DevTools MCP 0.10.6 adds PDF output and fixes tab targeting

Mozilla’s Firefox DevTools MCP connects agents to Firefox for browser inspection; its documentation says the developer preset adds debugging, network, console and profiler tools. The locally run server uses WebDriver BiDi via Selenium. Mozilla lists Node 20.19.0+, Firefox 100+ and clients including Claude Code, Claude Desktop, Cursor and Cline. The proposed evaluation configuration is npx -y @mozilla/firefox-devtools-mcp@0.10.6 --tool-preset developer --viewport 1280x720 --start-url http://localhost:3000. Mozilla announced 0.10.6 on October 16, 2026, documenting PDF output through print_page and profile reuse changes. According to Mozilla, select_page and close_page now target the tab identified in the last tab listing, even if tabs have since opened or closed.
