    Enables an MCP client to drive a real, already-logged-in Firefox session through a WebExtension rather than a WebDriver connection, so tabs, cookies and logins work as-is without relaunching the browser under remote-control flags. Exposes tools for tab listing and selection, navigation, accessibility-style snapshots, clicking, filling, typing, key presses, file uploads, screenshots and waiting, with per-origin permission grants and opt-in script evaluation.

A3.5/5.0

Scored across 35 tools

Disambiguation5/5

Every tool targets a distinct action or resource, with descriptions explicitly clarifying potential overlaps like press_key vs type_text, take_snapshot vs evaluate_script, and screenshot_page vs screenshot_by_uid. No two tools are indistinguishable.

Naming Consistency4/5

Nearly all tools follow a snake_case verb_noun pattern (e.g., list_pages, click_by_uid, install_extension). Minor deviations exist: screencast_start/stop use noun_verb order, and new_page is adjective_noun, but overall the naming is highly consistent.

Tool Count2/5

With 35 tools, the set exceeds the 25+ threshold for 'too many' and feels heavy for a browser automation server. While the domain is broad, several tools (e.g., accept_dialog/dismiss_dialog, clear_snapshot, clear_downloads) could be consolidated or grouped, making the count excessive.

Completeness4/5

The surface covers page management, element interaction, forms, downloads, extensions, screencasts, and script evaluation. Minor gaps exist for iframe/frame switching, cookie/storage management, and explicit wait tools, but these can be worked around via evaluate_script.
