Understanding Netflix Error M7399
Before diving into the solutions, it helps to understand what the error actually signals. Netflix Error M7399 is a browser-related issue that typically means your browser can’t store data properly, which is essential for Netflix playback. It affects popular browsers such as Chrome, Firefox, Edge, and Opera.
This error may be accompanied by a message like:
“Whoops, something went wrong… Unexpected Error. There was an unexpected error. Please reload the page and try again. Error Code: M7399-1260-00000024.”
Common Causes of Error M7399
- Browser doesn’t have permission to store local data
- Your device’s internal storage is full or limited
- Using a browser that’s out-of-date
- Conflicting extensions or plugins
- Corrupted browser cache or cookies
- Antivirus software clashing with streaming protocols
Quick Troubleshooting Steps
1. Enable Protected Content or Site Storage
Netflix needs to store a small amount of data in your browser to function correctly. If this setting is disabled, you’re likely to see the error.
In Google Chrome:
- Click the three-dot menu in the top-right corner and go to Settings.
- Scroll down and click Privacy and security > Site settings.
- Click on Cookies and site data.
- Make sure that Allow sites to save and read cookie data is enabled.
Also, make sure protected content is enabled:
- Go to chrome://settings/content/protectedContent
- Toggle on the option for Sites can play protected content.
2. Clear Cached Data and Cookies
Corrupted or outdated cached data may prevent Netflix from functioning smoothly.
How to Clear Cache in Chrome:
- Go to Settings > Privacy and security.
- Select Clear browsing data.
- Choose a time range like All time and check the boxes for Cookies and other site data and Cached images and files.
- Click Clear data.
3. Update Your Web Browser
Outdated browsers can cause compatibility issues with Netflix’s playback system. Always use the latest version of your preferred browser.
How to Update Google Chrome:
- Click the three-dot menu > Help > About Google Chrome.
- The browser should automatically check and install updates.
- Restart the browser afterward.
4. Free Up Disk Space
Netflix may return this error if your device is running low on storage. Make sure you have at least a few hundred megabytes available at a minimum.
To check your storage on Windows:
- Click the Start menu and go to Settings > System > Storage.
- Review and delete unnecessary files or move them to an external drive.
5. Check Your Browser Extensions
Some extensions, particularly those related to security or privacy (like ad blockers or VPNs), can interfere with Netflix playback.
Try running Netflix in an Incognito Window (Ctrl + Shift + N in Chrome). If it works, one of your extensions is likely the culprit.
Disable extensions one-by-one to identify the problematic one:
- Type chrome://extensions in the address bar and press enter.
- Toggle off each extension and refresh Netflix.
6. Restart Your Computer
It may sound simplistic, but restarting can clear temporary file issues, background processes, and software bugs that could be affecting browser performance.
7. Disable Antivirus or Add Netflix as an Exception
Some antivirus software may block browser-based DRM features necessary for Netflix. Temporarily disable your antivirus software and try Netflix again.
If Netflix streams successfully, check your antivirus settings and add Netflix or your browser as an exception to prevent future conflicts.
Advanced Fixes (If Nothing Else Works)
1. Try a Different Browser
If you’re stuck, switching browsers can save you time. Often, problems that occur in Chrome won’t happen in Firefox or Microsoft Edge. Netflix supports multiple browsers—use whichever works best and keep a backup option ready.
2. Create a New User Profile
Browsers like Chrome let you create individual user profiles. Sometimes corrupted profile settings can trigger the M7399 error.
- Click your profile icon at the top-right corner of Chrome.
- Select Add and create a new user.
- Open Netflix in the new profile and see if it works correctly.
3. Ensure DRM (Digital Rights Management) is Enabled
Netflix uses DRM to protect its content. If this feature is disabled or restricted on your browser, playback won’t function.
For Firefox:
- Go to about:preferences in the address bar.
- Scroll down to Digital Rights Management (DRM) Content and make sure it’s enabled.
Still Having Trouble? Contact Netflix or Your Browser Support
If none of the above solutions work, the problem may lie deeper in system configurations, third-party software conflicts, or even account-specific restrictions. Reaching out to Netflix support or your browser’s help center is a good next step. Make sure to mention all the troubleshooting steps you’ve already tried to speed up the process.
Preventing the Error in the Future
- Keep your browser and OS updated regularly.
- Avoid installing sketchy extensions or plugins.
- Make frequent use of incognito mode when troubleshooting playback issues.
- Periodically clear your cache and unnecessary browser data.
Final Thoughts
Netflix Error M7399 can indeed be a minor hiccup rather than a serious issue if you know how to decode its meaning and take appropriate steps. A few minutes of navigation through browser settings and general system health checks can get you back to enjoying your favorite content without disruption. By keeping your browser tidy and up-to-date, and knowing where to look when issues arise, you’ll spend less time troubleshooting and more time streaming.
