If you are using the Print button - '''don't''' - if you want to print a selection. Make your selection, then use the print dialog box from the keyboard using '''{ Ctrl + P ]''', thereby bypassing the print preview screen (which is what kills the selection). The Print Range > Selection should be available when using the keyboard command. ''BTW, I filed a Bug report about this regression back in July for Firefox 30. It was conformed, but no action yet by the developers.'' https://bugzilla.mozilla.org/show_bug.cgi?id=1037824 ''(Please don't comment in that Bug report unless you can provide a patch to fix the problem or confirm it as a Bug regression again.)'' https://bugzilla.mozilla.org/page.cgi?id=etiquette.html
