Took some time to find out, which plugin causes the problem, but:

can confirm the facebook issue.

I couldn't post or access chats with this enabled.

Same here, the comments box kept on disappearing, and the status box also, the chat boxes, ...
I had to disable the plugin for now
I've switched to Glitter Drag which works fine for me https://addons.mozilla.org/en-US/firefox/addon/glitterdrag/

[sclient]

Same issue FF 59 here.

Also in Fx 60 Facebook get's distorted in several ways. Even if fire-drag is the only active addon, FB has several issues.
