Clear Your Browser Cache: There may be old data or remnants of the plugin still stored in your browser’s cache. To clear the cache:
In Google Chrome: Go to Settings > Privacy and security > Clear browsing data > Select “Cached images and files” and click “Clear data.”
For other browsers, follow similar steps to clear the cache.
Check Your Browser Extensions: Even though you’ve removed the plugin, some browsers may not fully disable it. Open your browser’s extensions page (in Chrome, go to chrome://extensions/), check for any active extensions, and disable any that might still be running. Afterward, restart the browser.
Restart Your Browser: Once the cache is cleared and extensions are disabled, fully close and restart your browser. This can help remove any lingering remnants of the plugin.
Reload the Page or Try a Different Browser: If the issue persists, try reloading the page or testing it in a different browser to see if the pixels still appear.
Use Developer Tools to Remove Pixels:
Right-click on the page and select “Inspect” (or press F12) to open developer tools.
Go to the “Elements” tab and find the HTML elements that correspond to the visible pixels, then remove them manually.
