Testing Toolkit

Testing Toolkit brings essential QA tools together in a single extension:

* UA Inspector: View, parse, copy, and override the User-Agent for the active tab with built‑in presets or custom strings.
* Screen Capture: Full-page or selection captures with in-browser annotation and saving; includes screen recording shortcuts.
* Network Throttling: Apply ready-made speed presets (e.g., Slow 2G, 3G, 4G, No throttling) to the active tab for quick performance checks.
* Base64 Encode/Decode: Convert text to/from Base64 with instant copy helpers.
Designed for testers and developers, it keeps tasks fast and organized without juggling multiple tools.
