Working fine here on Firefox 57.0.2 (the latest stable release):

What version are they running? (visible at `about:support`)

Are there any errors in the console? (visible with Ctrl Shift k, or Menu → Web Developer → Web Console)

Does it work when all add-ons are disabled? (you can restart Firefox in [safe mode](https://meta.discourse.org/t/53504?silent=true) by going to `about:support` and hitting `Restart with Add-ons Disabled...`)

Does it happen on all Discourse instances, or just yours?
