FF56 in Win 10. I'm trying to enable multiprocess, and after disabling the remaining addon (after doing "Refresh"), about:support multiprocess shows "disabled by accessibility tools". After googling, in about:config I tried setting accessiblity.loadedinlastsession false and accessibility.lastloaddate reset, but those aren't being saved, so about:support still says multiprocess is disabled. Any suggestions on why the settings aren't sticking? Like I said, a Refresh didn't work. TY.
