Comment (by gk):

 We had a cypherpunk in #tor yesterday some noted the following interesting
 bit:
 {{{
 On Tor Browser, if I have my security slider to safest and change
 `svg.disabled` & `gfx.font_rendering.opentype_svg.enabled` in
 `about:config` in the order it bumps my security settings down to safer.
 However, if i toggle `gfx.font_rendering.opentype_svg.enabled` first then
 `svg.disabled` the security slider remains on high.
 }}}
