If you upgrade to Nightly 57 and have CTR (ClassicThemeRestorer) addon installed (like many people have), then this will break your UI (e.g. tabs broken, toolbar not clickable). I also was not able to uninstall any extensions (maybe related to bug 940449).

We really need to test this carefully, otherwise this might break many installations. Attached is a screenshot of what I saw.

I closed the browser, moved the CTR .xpi out of my extensions directory and restarted to fix this problem.
There is no expectation of legacy add-ons working well with 57. The problem is we haven't enabled yet the default disabling of those add-ons in 57.

I marked the add-on as incompatible now, to mitigate the problem, given it's popularity.
