I found out that if i was including the callback function within <?php … ?> like this :

<?php
....
function mytheme_comment($comment, $args, $depth) {
   $GLOBALS['comment'] = $comment; ?>
   <li <?php comment_class(); ?> id="li-comment-<?php comment_ID() ?>">
     <div id="comment-<?php comment_ID(); ?>">
      <div class="comment-author vcard">
         <?php echo get_avatar($comment,$size='48',$default='<path_to_url>' ); ?>

         <?php printf(__('<cite class="fn">%s</cite> <span class="says">dit:</span>'), get_comment_author_link()) ?>
      </div>
      <?php if ($comment->comment_approved == '0') : ?>
         <em><?php _e('Your comment is awaiting moderation.') ?></em>
         <br />
      <?php endif; ?>

      <div class="comment-meta commentmetadata"><a href="<?php echo htmlspecialchars( get_comment_link( $comment->comment_ID ) ) ?>"><?php printf(__('%1$s at %2$s'), get_comment_date(),  get_comment_time()) ?></a><?php edit_comment_link(__('(Edit)'),'  ','') ?></div>

      <?php comment_text() ?>

      <div class="reply">
         <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?>
      </div>
     </div>
<?php
        }
?>

it was working better than adding at the end the following code:

<?php
function im_comment($comment, $args, $depth) {
   $GLOBALS['comment'] = $comment; ?>
   <li <?php comment_class(); ?> id="li-comment-<?php comment_ID() ?>">
     <div id="comment-<?php comment_ID(); ?>">
      <div class="comment-author vcard">
         <?php echo get_avatar($comment,$size='48',$default='<path_to_url>' ); ?>
         <?php printf(__('<cite class="fn">%s</cite> <span class="says">says:</span>'), get_comment_author_link()) ?>
      </div>
      <?php if ($comment->comment_approved == '0') : ?>
         <em><?php _e('Your comment is awaiting moderation.') ?></em>
         <br />
      <?php endif; ?>
      <div class="comment-meta commentmetadata"><a href="<?php echo htmlspecialchars( get_comment_link( $comment->comment_ID ) ) ?>"><?php printf(__('%1$s at %2$s'), get_comment_date(),  get_comment_time()) ?></a><?php edit_comment_link(__('(Edit)'),'  ','') ?></div>
      <?php comment_text() ?>
      <div class="reply">
         <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?>
      </div>
     </div>
<?php
        }
?>

To call the function, i used:
wp_list_comments('avatar_size='.$avsize.'&callback=im_comment');

and after:
wp_list_comments('avatar_size='.$avsize.'type=comment&callback=im_comment');

As a result, the theme and its parameters are remaining but the comments are not showing.

Thanks for your help.
How can you validate pages when your work on a local server pls?

Ok I found my mistake.
Just forgot to put <?php

Next one:
My theme is coded with:
wp_list_comments('avatar_size='.$avsize);

I want to keep it as i would prefer to remain with the original avatar settings instead of doing it with the callback function.

I need to add this line to call the callback function:
<?php wp_list_comments('callback=mytheme_comment'); ?>

How can i add those two lines together please? only one <?php wp_list_comments()

Thank you for your help.
I had already uninstalled the linkification plugin in Firefox.
I had also disabled the wordpress plugins.
But remained with the same problem.

I can not understand where it is coming from:
Firefox, WordPress.

My theme is not responsible for this problem.
I already checked with the development team.

If it was due to my other firefox plugins, then you should see the video.
Do you see it?

If i look at this page with safari (i did not install any plugin), i still can not access the video.

Any idea?
