If I copy CKEditor's text with Firefox and paste it into a mail or any text editor a double line is inserted.
For example if my CKEditor text is:
line1
line2
line3
and I copy/paste this into a mail it shows as:
line1
line2
line3
This problem only occurs with Firefox, not Safari or Chrome who do not add extra line break.
To workaround this I had to set CKEditor as enterMode "BR" but it doesn't seem to be the cleanest way to do it.
Is there a better way to handle this?
