We have a lot of cache and off main thread script things that probably hold strong references to script nodes. Bug 1395233 probably looks like that. If you can reproduce, you can try disabling the bytecode cache and seeing if it helps. FWIW, I'm seeing a lot of ghost windows, for pages that I opened via links. I'll have to see if they are similar, or maybe they are bugs in the ghost window algorithm.

I can't immediately reproduce by visiting the site unfortunately. I think I just scrolled through looking at headlines. I might have had a loading throbber when I closed the page.

In particular the "encoding" part would be the one which holds a strong references. If this is the encoder, you should be able to reproduce it: · Either by loading the page 5 times, after clearing the cache, · Or by loading the page, after setting "dom.script_loader.bytecode_cache.strategy" to -1 and clearing the cache.

At one point my bug 1409115 leak was held by a script element, so maybe this is the same thing.

Are you still seeing this? Or should we close this as incomplete?

I haven't seen it recently. I'm going to mark this incomplete to make room for all new leaks in 2018!
