## Summary
Mozilla released Firefox DevTools MCP 0.10.6, a Model Context Protocol server that lets AI assistants control Firefox via WebDriver BiDi. The update adds a print_page tool that saves pages as PDF with landscape and background options using print CSS. Several tab-management tools now use WebDriver BiDi instead of bringing tabs to the foreground, and profile-path handling was fixed to avoid creating nested profiles.

## What changed in 0.10.6
- **print_page tool**: New PDF export with optional landscape orientation and background rendering; uses print CSS for style verification
- **profile-path fix**: Reuses profiles marked with `.firefox-devtools-mcp` file; unmarked paths still create `firefox_devtools_mcp_profile` subfolder
- **WebDriver BiDi adoption**: `list_pages`, `select_page`, `close_page`, `navigate_page`, `new_page` now read tab state via BiDi instead of foregrounding tabs
- **Tab state accuracy**: `select_page` and `close_page` operate on last known tab list even if tabs changed since; unloaded restored tabs excluded from `list_pages`; unreadable titles fall back to `(unknown)` after 1 second timeout

## Why it matters
The MCP server targets developers building AI-assisted browser automation workflows. The PDF export tool fills a gap for headless print-style validation, while the BiDi migration reduces UI disruption during automated tab operations.
