Why FF uses "\n" line endings in tag textarea, but when data sent to server it uses "\r\n" line endings?

I type a text into a textarea and by using a jQuery expression: `$('textarea:first').val().replace(/\r/g, 'R').replace(/\n/g, 'N')` it shows that FF uses "\n" endings and once the form is submitted the "\n" line endings are replaced with "\r\n" line endings

The problem is in incorrect text length for multi line text - on browser side it is less due "\n" line endings and on the server side it is longer due "\r\n" line endings and raises some text length validation inconsistency between browser and server sides.

Hi vparamon, I do not want to say that this is a statement beyond the scope of this forum, because I know you can file a bug with troubleshooting information and steps to reproduce this with an example. However I also know it has to be reproducible. Is this unique to your server? If not please file a bug at http://bugzilla.mozilla.org with an example to make it easy to reproduce.

Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox.
