En fait sous safari le backend existe, et c'est accessible par javascript. Par contre effectivement a ma connaissance il n'y a juste pas d'UI (peut etre une extension ?)

'In the "Did you know Safari could do this?" category comes the following tip. Safari supports an extension for examining the preferred stylesheet set and for setting the current active stylesheet set, so if you want to swap between sets of sheets in Safari, you don't have to loop over all of them setting the disabled property. You can get and set the selected set using an extension on DocumentStyle called selectedStylesheetSet.'
