Sounds like, so DUP of Bug 97278 - Retain original source formatting: Composer adds newlines when switching view modes (extra empty space added). See http://forums.mozillazine.org/viewtopic.php?f=5&t=634299 for possible work-around.

An other similar one is "Bug 1070502 - Composer inserts multiple empty lines into document's source code ". My suggestion: Mark this one and all other similar ones as DUP of Bug 97278 and test newly after fix for that Bug.

No objections, so I DUP this one. @Reporter, please test again when we have a fix for Bug 97278 and reopen this one, if the fix does not heal this particular problem here.
