1289063 - Firefox 47 crashes in XGetInputFocus when trying to show PDF in Adobe Reader plugin

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Carsten Sommer]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.63 Safari/537.36

Steps to reproduce:

When opening a PDF file in FF 47 on Ubuntu 14.04 using the Adobe Reader Plugin 9.4, only the first time succeeds. E.g. https://www.einfach-fuer-alle.de/download/ , trying to show the EfA-Kalender2007.pdf PDF file. 


Actual results:

If I close the first tab and try to re-open the same PDF again, Firefox segfaults in XGetInputFocus.


Expected results:

FF should not have segfaulted.



Somehow FF didn't collect a crash report even though the option is enabled. So I collected a back trace manually:


Program received signal SIGSEGV, Segmentation fault.

Comment 1

[Benjamin Smedberg]

Carsten, are you using the mozilla.org build or the Ubuntu distro build of FF47?

karlt, perhaps/probably gtk3 related?

Comment 2

[Carsten Sommer]

I'm using the Ubuntu build.

Comment 3

[Karl Tomlinson (:karlt)]

Thanks for the stack trace.

dpy is zero and so perhaps mGdkWindow is zero.
That would be from this change:
https://hg.mozilla.org/mozilla-central/rev/875cb4f20eac2544dc1d3249ed7cffe4e3962f63#l2.218

Other parts of Xt plugin focus code were also disable in that commit, but not all of it.  I don't recall how that code is meant to work, but I wonder whether this should not be happening in the browser process.

Really the best fix is to remove support for Xt plugins.  Adobe Reader plugin was very buggy last I looked and I doubt it has improved.

Comment 4

[Benjamin Smedberg]

Firefox no longer supports NPAPI plugins.
