Known Issues: Rich Text Editors (Facebook, Outlook, etc.): Some modern websites use complex rich text editors that may not support automatic text replacement: Facebook Posts/Comments - Text replacement may not work in the status update box or comment fields. Use the popup's "Quick Encrypt" feature instead. Outlook Web - Rich text email composition may not support direct replacement. Copy encrypted text from the popup and paste manually. Discord/Slack - Some formatting-enabled chat boxes may clear the encrypted text. The popup method works reliably. WhatsApp Web - Message input field may not support replacement on some browsers. Workaround: Type your message in the extension popup's Quick Encrypt box Click encrypt (auto-copied to clipboard if enabled) Paste the encrypted text manually into the problematic field Why this happens: These sites use contenteditable divs with complex JavaScript frameworks (React, Vue) that can override or reset content changes made by browser extensions. Alternative: The extension always saves your last encrypted text in the popup for easy copying, making it simple to work around these limitations.
