Does it work for you with current nightly / beta? Is there anything in the browser console?

Do you have any other interesting prefs changed? That is, does it work on a clean profile where you only toggle print.tab_modal.enabled?

Thanks!

Please run firefox on terminal as:

G_DEBUG=fatal-criticals firefox

(i.e. with G_DEBUG=fatal-criticals set). Then Firefox should crash when this line is printed:

(firefox:17079): GLib-GObject-CRITICAL **: g_object_ref: assertion 'G_IS_OBJECT (object)' failed

co please submit a crashreport and paste the crash signature here.

Thanks.

I meant, does it work if you download a build from https://nightly.mozilla.org?

That being said the browser console makes me think this is just bug 1663503 (which is one of the reasons this pref is not default-on for releases).

The product::component has been changed since the backlog priority was decided, so we're resetting it.
For more information, please visit auto_nag documentation.

Or bug 1662946, which is now fixed on Nightly.

I also think it would be useful to know if a Firefox Nightly build downloaded from that page works for you, Anton.

I try firefox-83.0a1.ru.linux-x86_64.tar.bz2 from https://nightly.mozilla.org
Working fine, print preview worked.

Thanks for testing. I'll close this as fixed by bug 1662946 then. The fix from that bug should be uplifted to Beta 82 for the Beta build that goes out around the middle of this week.
