For Chromium-based browsers
Shieldly is positioned for browsers in the Chromium family, including Chrome, Edge, Brave, Opera, Vivaldi and Arc where Chrome-style extension support is available.
Manifest V3 protection
The extension uses a modern browser extension model for filtering, page cleanup, protection modes and site-specific controls.
Privacy and portability
Local settings, import and export, custom blocked domains and diagnostics make Shieldly useful across repeated browsing setups without depending on a remote account.
Chromium is a starting point, not a compatibility guarantee
Browsers can share the Chromium engine while differing in extension distribution, available APIs and administrative policy. Before installing Shieldly, check whether your desktop browser accepts the linked store extension and exposes its requested permissions. A matching engine alone does not establish support on phones, embedded browsers or heavily customized builds. The store's result and a working extension control panel are useful initial checks, followed by a test on a regular website.
Verify the features you plan to use
After installation, inspect the protection mode and the modules you need. Test ordinary ad cleanup separately from a video player, consent handling or WebRTC behavior because these use different mechanisms. Run Diagnostics when a feature appears unavailable. Include the full browser name and version in a report rather than describing it only as Chromium; that distinction helps explain missing APIs or settings managed by another extension.
Use a browser-specific setup guide
Start with the Chrome, Edge, Brave, Opera or Vivaldi guide when it matches your browser. Those pages address installation and overlapping browser protections more directly. For another Chromium build, keep configuration changes small and check one site at a time. If migrating, export the original settings and inspect the destination after import. Do not assume that browser sync, matching icons or identical tab layouts mean that Shieldly configuration has transferred.
Frequently asked questions
Does Chromium support mean Firefox or Safari support?
No. These pages describe the Chrome-compatible extension build. They do not establish a separate Firefox or Safari release.
What is a good first compatibility test?
Confirm installation, open Shieldly, enable the intended module and reload a regular page. Then check a second page with a different layout before drawing a conclusion.
