Attachment: screenshot of infinite (?) recursion death-spiral

It kinda looks like the page was getting into some sort of infinite recursion here, in their fetchBids script. See screenshot showing the recursion (chunks of the same calling functions, repeating indefinitely as I drill down).

I wonder if this was just something that was broken (or failing catastrophically) in the site's ad script for a temporary period?

Can you still reproduce the issue?

Comment 3

If you can still reproduce, I wonder if the issue goes away with addons disabled, too? I see ublock origin in your about:support -- I wonder if that's interfering with the page's ad scripts in a way that makes them fall over like this.

I can't reproduce this any more.

Comment 5

[Daniel Holbert [:dholbert]]

Great, thanks for letting us know. Given comment 2, it feels likely that this was likely an issue on the website's side, either in their JavaScript logic or in a fragile dependency on a third-party resource. I'm glad it seems to have been resolved.
