Just to clarify what’s going on, for the benefit of future thread readers. It seems that when using Safari or Firefox to edit a page, something hinky happens to the code if you leave the WYSIWYG editor on even if you don’t use it!
In my case, I would be on my site and click on the “edit this page” link, which would open up the admin area to do this. By default, it displayed the WYSIWYG and then I’d switch to the code editor to add some paragraph and break tags. It all looked good and I’d save it and then check the live site to make sure it worked. However, if I ever go back to edit that page, the process of reopening it and having the WYSIWYG display seemed to strip out all my paragraph and break tags!
The only way I got it to work was, as Moshu posted above, to turn off the WYSIWYG capability altogether.
