TestYourBrowser™ provides browser diagnostics and guides that you can verify. Run a test, match the failing line, apply a scoped fix, and re-test.

Browser diagnostics for real-world problems

Most 'browser bugs' are a layer problem. It can be a permission, a policy, a network path, a codec, a GPU fallback, or a storage rule. Our tools are designed to make the failing layer obvious so you can fix it quickly.

On-device browser tests

Run targeted tests to confirm feature support and common failure modes. These pages show real results from standard web APIs.

Run the Full Browser Test

→Full Browser Test and quick Capability Test
→Feature tests: WebGL, WebRTC, HTML5, CSS, storage, cookies, codecs
→Device signals: screen, touch, user agent
→Clear outcomes you can share with support or IT

Readiness checks for real workflows

Answer practical questions with a single page. These checks combine multiple signals into a simple 'ready vs blocked' view.

Check gaming readiness

→Gaming readiness (GPU path + WebGL)
→Video call readiness (camera/mic + WebRTC)
→Fast verification after you change a setting
→Links to the exact guide that matches the failing line

Step-by-step troubleshooting guides

Fix common issues with guides that include verification steps, sources, and review metadata. You re-run the test after each change.

Browse guides

→Permission fixes: camera, mic, notifications, clipboard
→Storage fixes: cookies, localStorage, IndexedDB, third-party cookies
→Graphics and performance fixes: hardware acceleration, WebGL failures
→Media fixes: codecs, DRM (Widevine) problems

Support-ready checklists

When a problem is hard to reproduce, a checklist beats a guess. Use these pages to isolate the layer and collect the signals that matter.

WebRTC troubleshooting checklist

→Fast decision trees (permissions vs network vs codecs)
→Suggested data to share with IT or a vendor
→Scoped fixes first (per-site settings before global toggles)
→Primary sources linked for deeper context

Avery Collins

Founder and Editor

Avery started writing troubleshooting notes while working in IT support, where 'it works on my machine' rarely meant the issue was gone. That job turned into a long-running habit: reproduce the failure, isolate the layer, and write down the exact steps that make the result change.

Dana Brooks

Technical Editor

Dana has spent most of her career in the space between 'support ticket' and 'engineering fix.' She started on a help desk, moved into QA, and then owned internal runbooks for diagnosing browser and device issues across a wide range of machines.

Noah Kim

Privacy and Security Writer

Noah writes the guides that sit at the intersection of privacy settings and day-to-day usability. Many browser 'breakages' are side effects of a privacy control working as designed. Third-party cookies get blocked, storage becomes partitioned, and permission prompts get suppressed after repeated denials.
