Someone left my Gmail in debug mode

I don’t know what’s going on with my Gmail, but I thought I’d share, since there’s some really strange things going on here, if anyone is interested. The screenshots are the bottom of this post.

The first window is what I opened my Gmail up to. Notice the “Why was the last action slow?” text at the top, under the search bar, as well as some debugging information in the lower-right under the “Details” link, and a skull icon in the lower-right corner.

When hovering over the skull icon, I’m presented with a bunch of links that don’t change my cursor to a pointing finger, but they are clickable, and I took a screenshot of each of those links.

Is this some kind of Gmail debug mode that I can’t escape from?

When clicking “Why was this action slow?”, this is what popped up — a sort of trace through the internal structure of Gmail.
