firefox-devtools-mcp vs context-mode
firefox-devtools-mcp: Firefox DevTools MCP is a Model Context Protocol server that allows AI assistants to control Firefox via WebDriver BiDi. It works with Claude Code, Claude Desktop, Cursor, and other MCP clients. It provides tools for page navigation, snapshots, network requests, console messages, and more.; context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.

firefox-devtools-mcp01Automates Firefox via WebDriver BiDi
02Works with multiple MCP clients
03Provides comprehensive browser automation tools
04Supports headless mode and existing browser connection
05Network and console monitoring
context-mode01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.
