In Debian 10, firefox-esr 78.5.0esr-1~deb10u1, what mechanism is available to control rendering of a tab character? https://wiki.debian.org/Firefox doesn't mention "tab" or "css". Is there a user editable css file for firefox? Thx, ... P. -- cell: +1 236 464 1479 Bcc: peter at easthope. ca VoIP: +1 604 670 0140
