That 2885ms DOMEvent part looks maybe-interesting? 710ms GCMajor in there too.

DOMEvent here means just that we run some very heavy JS in a load event listener.
I don't see 710ms major GC anywhere. It is a major GC which has several slices and time between the first and last is 710ms.

What is the website doing when loaded?

oh, is it XHR's load event, not page's.
The profile seems to miss some proper symbols.

This was captured while inputting text into the editor, a short one line query followed by submitting the result.
I ran the mozregression tool to test if this were a firefox regression starting on 2017-07-01. I get consistently poor performance going back in nightly, but the tool has run fine in the last few weeks.
I see the same poor behavior on Chrome, this is a redash issue.
Moving this since we have confirmed this is a re:dash issue.

I'll mention for the sake of mentioning that there could still a Firefox perf win to be had here, even if it was a re:dash change that made things worse.
I haven't noticed any major performance pain using STMO in nightly recently. Is this still happening for you Frank?

Yup, this was fixed in re:dash at some point :)
