FAQ

A few things worth knowing.

What does Shieldly block?+

Shieldly is designed to reduce common ads, trackers, visible ad placements, YouTube interruptions and optional page distractions such as pop-ups or cookie walls.

Does Shieldly upload my browsing history?+

The extension is designed around local browser storage for settings and statistics rather than uploading your browsing history for personalization.

Can I disable protection for one website?+

Yes. You can use per-site controls, allowlists or temporary pause options without turning Shieldly off everywhere.

What are Compatibility, Balanced and Strict modes?+

They give you different protection levels so you can prioritize site compatibility or stronger cleanup depending on what you are browsing.

What are SafeClick and WebRTC leak protection?+

SafeClick helps reduce fake buttons, redirects and alert traps, while WebRTC leak protection is designed to reduce local IP exposure through browser WebRTC behavior.

Does Shieldly include Netflix Assist?+

Yes. Netflix Assist is designed to reduce supported streaming ad interruptions and page clutter without trying to bypass subscription terms or breaking playback.

Getting started

Set up protection around your browsing

Start with the guide for your desktop browser, install Shieldly from the linked store listing and review the requested permissions. Open the extension in the profile you intend to protect, check the active mode and reload a regular website. Browser-owned pages and store pages have restrictions, so they are not representative tests of filtering.

Choose the control that matches the problem

Use tracker blocking for supported background tracking requests, pop-up controls for unwanted overlays and consent handling for supported banner interactions. These features have different jobs. Hiding an overlay does not itself prove that a website rejected optional cookies or stopped processing data.

Keep the pages you need working

If a form or player breaks, repeat the failing action after a narrow site-specific adjustment. Compatibility, Balanced and Strict are protection modes; optional Advanced features have a separate activation state. Change one setting at a time and avoid switching protection off everywhere to solve an issue on one website.

Understand video and privacy limits

YouTube filtering and Netflix Assist target supported browser behavior and can be affected by service changes. Netflix Assist is a beta feature, not a subscription replacement. WebRTC protection does not replace a VPN, and no ad blocker can promise anonymity or universal coverage.

Keep your configuration useful

Review old exceptions periodically, create a settings backup before moving profiles and inspect a diagnostic report before sharing it. Local settings and counters are useful context, but blocked requests and hidden elements are different events. Describe the actual page behavior when asking for help.
