I've fixed the issue with prompt injection and paragraph spacing. Here's what was done:

Identified the Problem:
The previous implementation used textContent which doesn't preserve formatting like line breaks
Prompts contain newline characters (\n) for formatting that weren't being converted to proper line breaks

Implemented the Solution:
For textarea elements: Kept the direct value assignment since textareas naturally preserve newlines

For contenteditable divs:
Added proper HTML escaping to prevent XSS vulnerabilities
Converted newline characters to <br> tags for proper formatting
Used innerHTML instead of textContent to preserve the formatting

Security Considerations:
Added HTML escaping before converting newlines to prevent XSS attacks
Maintained security while enabling proper formatting

The fix ensures that when users click the "Use" button, prompts are injected into ChatGPT with proper paragraph spacing and formatting preserved. Newlines in the prompts will now be correctly displayed as line breaks in ChatGPT, making the prompts much more readable and maintaining their intended structure.

The extension has been rebuilt successfully and passes all syntax checks.
