A patch which might fix this issue, too, is available at 1659988. https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988
Everyone affected, please give it a try and report back. I think it should fix your issues too. @Maintainers: This issue might duplicate https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659922 and https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1643200 or vice versa. I'm optimistic that 1659988 fixes all of these apparmor related issues (which is the reason I encourage everyone affected to try it out). -- 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/1627239 Title: Web pages not rendering with e10s enabled and AppArmor profile in enforce mode Status in firefox package in Ubuntu: Confirmed Bug description: STR: 0. Enable enforce mode for the Firefox app-armor profile: sudo aa-enforce usr.bin.firefox 1. Open Firefox 49 with clean profile (or force-enable e10s as per https://wiki.mozilla.org/Electrolysis#Force_Enable and restart Firefox) 2. Go to any site What happens: The site loads but the content is rendered blank. The page is loaded properly since I can hover over (invisible) links and see the cursor change & the address to be shown in the bottom of the window. What should happen: The site is rendered properly. This is related to e10s and the default AppArmor profile shipped with firefox. See the attached screenshot for how the first-run page looks like with a clean profile, e10s and AppArmor enabled.
