Prior to running:
sudo apt-get purge --remove xul-ext-ubufox
I ran into constant crashes with both Mozilla® Firefox®
48.0+build2-0ubuntu0.16.04.1 and 49.0+build4-0ubuntu0.16.04.1, extensions or no
extensions. This may be related to Bug 1612994 "firefox crashes constantly",
but don't yet know (as of 15 October 2016) whether 1612994 can be
satisfactorily marked a duplicate of this Bug.

Firefox 49+ multiprocess windows feature (e10s) is disabled by ubufox
Status in ubufox package in Ubuntu:
Firefox 49+ enables e10s by default:
But Ubuntu's "Ubuntu Modifications 3.2" extension disables it. In
about:support output it says:
"Multiprocess Windows 0/1 (Disabled by add-ons)"
If we manually disable "Ubuntu Modifications" extension, it works:
"Multiprocess Windows 1/1 (Enabled by default)"
I am using Xubuntu 16.04, firefox 49.0+build4-0ubuntu0.16.04.1,
