firefox 69 and css

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Bonjour, While upgrading to firefox 69, the css syntax to configure firefox seems to have been changed (once more..... programmers think that people have time to waste!) . Once upon a time, I found the syntax to have my tab-bar below the other bars (lot of waste time), and now, with the last version of firefox, this is lost. I continue to waste my time, desperatly searching what is the right syntax, but I did not find any clue. Does anybody have information? Thank you. - -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAl2A9IUACgkQdE6C2dhV2JUs0ACfYMu10iuR1nSx93A26F4/xorT YY0AoJOtjyndx2WBevQ31qOwY5dtqE67 =2yUU -----END PGP SIGNATURE-----
