let's have some fun with upcoming Firefox 57 a.k.a Firefox Quantum. This
is a major Firefox update with key - pleasant and unpleasant - changes:
- fastest than ever with Rust, CSS Stylo, Sandbox...
- new "Photon" look
- and disabled XUL extensions
Looks like the legacy addons still can be enabled by
extensions.legacy.enabled pref at about:config .
Unfortunately that does not work for the Beta/Release we have at updates
now. I'll try to enable it there but no promise.
according to the disruptive nature of the update which is planned to
land in *all* Fedoras at Nov 14 I decided to put the update to the
testing as soon as possible, which mean we have Firefox 57 Beta packages
at update-testing right now.
If you don't consume update-testing regularly you can install Firefox
# dnf update --enablerepo=updates-testing firefox
and also expect new versions there. Please give it a shot and report any
issue to our  or Mozilla bugzilla .
