Comment 12 for bug 1676164

Unbelievable: Canonical has released Firefox 57, which no longer supports XUL extensions (i.e. the ones in use since Firefox was created, and when Trusty was released), in 14.04 Trusty. This is breaking users' Firefox installations in a "Long Term Support" release. And still no official ESR package.

This is absolutely unacceptable. Ubuntu LTS releases can no longer be taken seriously. Back to Debian for me (a long time coming, but this is like the last straw). 10 years ago, Ubuntu was doing good work, making up for many of Debian's desktop weaknesses, but now Ubuntu isn't even trustworthy. Debian would never do something like this.
