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.
