Question

I have a site with some tables on it (with thead & tbody).
This site shall be printed with the latest firefox.
Problem: sometimes firefox breaks the page within one of the tables,
the printed version of the site is unusable.
Couldn’t find any working solution yet.

Answer 1

This shall fix the problem

table { 
   page-break-before: always;
} 

Update::

On that case, use the folloing

@media print {
    table {
       page-break-inside:avoid;
    }
}
