Feedback was provided regarding potential ReferenceErrors caused by the removal of Firebase scripts and a suggestion to use relative paths for internal links to improve portability.

Removing the Firebase v8 scripts from the top of the while keeping the v9 compat scripts at the bottom (lines 203-204) may cause a ReferenceError if main.js or feedback.js depend on the global firebase object. These scripts are executed immediately, whereas the compat scripts are loaded much later in the document. Consider moving the v9 compat scripts to the top of the to ensure they are available for subsequent scripts.

Using an absolute URL for internal links is discouraged as it makes the code less portable and is inconsistent with other relative links used in this file (e.g., line 312). Using a relative path is preferred for internal navigation.
