Just a heads-up: if you use Ghostery and you’ve started getting a popup telling you you’ve been logged out, and an unknown error logging back in, you might want to disable it:
I’m not sure what update it’s had recently, but it breaks the DT forum now. And it really needs to be disabled (as in, the entire add-on) not just paused, so it’s a bug somewhere in the code, not just an overzealous filtering rule.
