Firefox crashes/quits silently when trying to open a new tab after hosting it inside System.Windows.Forms.Integration.WindowsFormsHost in a wpf application.
I am working on an application where i need to dock various external windows applications inside my wpf application. I am using this structure for docking : Grid->WinFormHost->Panel->WinApplication[Firefox] . After firefox is docked using SetParent operation SetParent(Firefox process Handle, Panel Handle) and i try to open a new tab now , Firefox crashes or quits silently. This does not happen with other browsers like IE,Chrome,Opera. Please help.
OS : Windows 7 Firefox version : 34.0.5
I also tried on a different system with different version of firefox and had same problem there as well.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?
While still in Safe Mode,
In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.
Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.
I have updated my firefox to latest version i.e. 38.0.5. I started firefox with parameter -safe-mode . Firefox started in safe mode. I was able to dock it inside my wpf window as described earlier. Now I did a control click on one of the link on www.bing.com . Firefox crashed again .
I started firefox again manually while holding shift and typed in about:crashes. There were only 2 entries [with bp in front] that i had already submitted earlier when i first encountered this problem . Surprisingly i can see only those crash reports that i have submitted to firefox already.

I tried on 2-3 systems including desktop and laptop. I was able to replicate the issue on all of them.
The crash report is several pages of data that we need to see.

I'm not familiar with this idea of docking Firefox in another application.
Launching a new tab would seem to be a largely "internal" operation, but Firefox does have an optional feature to interact with Windows when doing that. Could you check this option, which defaults to OFF:
"3-bar" menu button (or Tools menu) > Options > General
At the bottom of the Tabs section, if "Show tab previews in the Windows taskbar" is selected, try deselecting it.
@jscher2000 - I tried the suggested setting by turning it on and off . Didn't help.
@FredMcd - Strangely when firefox crashes and i don't submit the crash report , i can't see any entry in about:crash page later. Last time it crashed after docking and trying to open a new tab , i submitted the details using crash dialog that appears. Please refer to url : [|5f4b441d-d7a6-48d4-9956-186c52150623 ] for details. Hope this provides required details you want me to copy paste here.
Hi Nish26, that crash report shows these attempted activities just before the thread crashed:
mozilla::widget::WinTaskbar::CreateTaskbarTabPreview() mozilla::widget::TaskbarTabPreview::TaskbarTabPreview() mozilla::widget::TaskbarPreview::TaskbarPreview() mozilla::widget::WindowHook::AddMonitor() mozilla::widget::WindowHook::LookupOrCreate() mozilla::widget::WindowHook::Lookup() dies on line 67 of WindowHook.cpp
(there are links into the source code from the rows listed under Crashing Thread)
That is consistent with my speculation of how Firefox might be reaching out to Windows when you create a new tab, but since you disabled the feature, I wasn't expecting Firefox to actually try it.
That crash is in a loop relating to a message data array that Firefox may be trying to populate using a Windows API call, but... I don't read C++ (and am not familiar with the APIs even if I did) so I really don't know.
Do you think someone who develops Windows Forms applications would be aware of a solution or workaround based on these tiny fragments of information?
Hi jscher ,
Even i work mostly in .net and have only basic knowledge of C++. Maybe I will try to pull source code during weekends and try to make some sense out of it.
