Looks like the bug was introduced in FF 55.0.2, here's a comment from one of our users.

I'm using 64-bit on a Lenovo Thinkpad E560. I just booted my old desktop which was not updated for a few weeks and tried with FF54 and Flash 26.0.0.137 and had no problems on it. Then I updated Flash first from .137 to .151, still everything working, then after updating FF to 55.0.2 I also have the crash of Flash on my desktop computer when opening the file selector dialog.

Flash crashes not only when opening the file selector dialog, context menu also cause crash

This works for me with latest Nightly 58.0a1, 20171010100200 on Ubuntu 64-bit Linux 17.04 with Shockwave Flash 27.0.0.159.

However, there are plenty of reports of this crash signature across all channels. https://crash-stats.mozilla.com/signature/?product=Firefox&signature=gdk_window_get_window_type&date=%3E%3D2017-10-04T14%3A36%3A00.000Z&date=%3C2017-10-11T14%3A36%3A00.000Z&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&_sort=-date&page=1#summary

crash-stats does contain a couple of reports with Shockwave Flash 27.0.0.159. So that isn't the difference in why I don't see this wehre others on 27.0.0.130 do.  Maybe it's Ubuntu 16.04 vs 17.04?

Yeah looks like it might be specific to Ubuntu 16 -

This needs an owner for investigation.

Flash is no longer supported.
