# per-user firefox configuration owner @{HOME}/.{firefox,mozilla}/ rw, owner @{HOME}/.{firefox,mozilla}/** rw, owner @{HOME}/.{firefox,mozilla}/**/*.{db,parentlock,sqlite}* k, owner @{HOME}/.{firefox,mozilla}/plugins/** rm, owner @{HOME}/.{firefox,mozilla}/**/plugins/** rm, owner @{HOME}/.gnome2/firefox*-bin-* rw, With the pre-51.0.1+build2-0ubuntu0.16.04.1 FF it worked fine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1659922 Title: Firefox 51.0.1 после обновления в Ubuntu 16.04 x32 не отображает содержимое сайтов Status in firefox package in Ubuntu: Incomplete Bug description: Firefox 51.0.1 после обновления в Ubuntu 16.04 x32 не отображает содержимое сайтов.
