Hi! If large sites like Facebook and X are partially loading in Firefox while other browsers work fine, and the issue resolves itself after several hours, this usually points to a temporary network or content delivery issue, rather than a permanent problem with Firefox. A few things you can check: '''Clear cache and cookies''' Go to Settings → Privacy & Security → Cookies and Site Data → Clear Data… Clearing cached content can fix missing images or partial page loads. '''Check extensions''' Some extensions (ad blockers, privacy tools, script blockers) can block site content. Try Troubleshoot Mode (Menu ≡ → Help → Troubleshoot Mode) to see if the sites load properly without extensions. '''Make sure your Firefox is up-to-date!!''' Hope this helps!
