how do i stop the flashing on my yahoo home screen

Hi! If the Yahoo homepage keeps flashing or disappearing and reappearing in Firefox, this is often caused by an extension, hardware acceleration, or corrupted site data. Please try these steps: 1. Open Firefox's ☰ menu → Help → Troubleshoot Mode… and restart Firefox in Troubleshoot Mode. 2. Open Yahoo and see whether the flashing continues. 3. If the problem stops, an extension or customization is likely causing the issue. You can disable your extensions one at a time to identify the culprit. 4. If it still happens, go to Settings → General → Performance, uncheck Use recommended performance settings, then uncheck Use hardware acceleration when available. Restart Firefox and test Yahoo again. 5. You can also clear Yahoo's site data and reload the page. If Yahoo works normally in another browser, please tell us your Firefox version and Windows version, and whether the flashing occurs on other websites too. This information can help determine whether the problem is specific to Yahoo or Firefox.
