@dupondje Not exactly: In my case FF was broken directly after the update to 51.0.1, without any further change, including configuration and extensions/plugins.
And yes, by its nature, it's a regression. Not in FF upstream, but in the ubuntu package (apparmor profile). The problem itself could be older: I have seen this issue earlier (FF49/50), when playing around with E10S manually (in about:config). Up until FF50 that could be worked around, but my workaround (installing extension "ubuntu modifications") does not work any more for 51.0.1. -- 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 does not display pages/shows blank pages.
