Lyncor Guard od Lmncry

Lyncor Guard is a local-first Firefox extension focused on privacy, performance, convenience and lightweight site automation.

The extension is designed to keep unnecessary background activity to a minimum. Features are enabled only when needed, and settings and statistics are stored locally in Firefox.

Main features:

• Privacy and security tools
Cookie consent handling, tracking URL cleanup, embed protection, WebRTC and referrer controls, IDN/Punycode protection, download safety, clipboard protection and other optional browser hardening tools.

• Performance tools
Smart tab management, reduced background media activity, animation control and network optimizations designed to reduce unnecessary resource usage.

• YouTube Toolkit
Optional YouTube enhancements including autoplay control, theater mode, Shorts controls, playback speed preferences and timeline integration.

• SponsorBlock API integration
Lyncor Guard can use the public SponsorBlock API and community-provided segment data to identify and skip selected segments in YouTube videos.

SponsorBlock is an independent open-source project. Lyncor Guard is not an official SponsorBlock client and is not affiliated with the SponsorBlock project.

• Media Save
Finds supported video and audio media on the current page only when requested by the user. Media Save does not continuously scan pages in the background.

• HoYoLAB tools
Optional HoYoLAB Daily Check-In automation and a Genshin Impact Resin Monitor for displaying current Original Resin information.

• Site automation
Optional tools for supported websites, including Twitch Channel Points collection and FunPay offer auto-raise while the relevant website is open.

• Per-site controls
Disable Lyncor Guard completely on selected websites or create individual site profiles with custom settings.

• Presets
Quickly switch between predefined protection levels or create a custom configuration.

Privacy:

Lyncor Guard has no user account and no Lyncor Guard telemetry service. Extension settings, counters and preferences are stored locally in Firefox.

Some optional features communicate directly with the third-party services they are designed to work with, such as SponsorBlock or HoYoLAB. These integrations can be disabled by the user.

Lyncor Guard is built specifically for Firefox.
