Status: RESOLVED WORKSFORME

Attachment: Firefox_32bit_64-bit_Ancestry_DefaultUploadFolder_01-18-2016_munched.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20160105164030

Steps to reproduce:

In Ancestry, I open a Windows File Explorer window to upload a file.  In the 32 bit version, the Windows Explorer opens as expected showing the navigation pane; the 64 bit version does not have the navigation pane.  This is the only difference I have seen so far in the 2 versions of the browser.  

I am using Windows 7 Pro operating system on a personal computer.  


Actual results:

In the 64 bit version, the Windows Explorer does not show the same options that I have in the 32 bit version of Firefox.  In the 64 bit version, I do not get a windows with the Navigation pane on the left, nor the options to set it to open.  Doing the same function in the 32 bit Firefox opens as expected.  
I have tried setting and re-setting the options and "apply to all folders" etc. for the Windows Explorer with no change in behavior. 


Expected results:

I expect the same views for finding files to upload in both versions of the browser.  I'm attached a snip showing the way they look (64 bit on the left - incorrect; 32 bit on the right - correctly).  When downloading a file, both versions of the browser both work correctly and the same way. It is only on upload that I see the differences. I uploaded the separate images to https://app.box.com/s/8ab2avj74bllvgd4zsj9nzzp48b4j4d0 if that is easier to see.

WFM on Fx43.0.3 32 & 64 bit. Can you provide a sample page to reproduce it?

Good idea :) 
I created a test guest account on Ancestry.com.  ID = [e-mail]  PW = Firefox64
Go to Ancestry.com.  
 Using the 32 bit version of Firefox, Sign in with those above. There are 2 people in a family tree called "A Test Family Tree" and you have Editor rights so can do anything to that tree.  
 Click on John Smith or Mary Jones, then click their Profile.
 When you see the Profile page, click on Gallery, then in the middle click on "Upload Photos" - or on the right button ADD, then select Upload Photos. 
 At that point, you will the Windows Explorer window - with a navigation pane.

Try again using the 64 bit version of Firefox and you will see the difference - when it brings up Windows Explorer to upload, there is NO navigation pane.

I bet this is a sandbox issue.

I would have too. :-)
However, if I disable the sandbox it doesn't fix it.

Actually, this appears to be because 64-bit doesn't have protected mode.

If I disable protected mode on 32-bit then you get the same style of dialog as 64-bit.

I notice that the protected mode dialog appears aligned with the main window.
It appears that in protected mode windowless plugins flash gets hold of the HWND from the parent.
Now if they did change it to do that for 64-bit, it would then get blocked by the sandbox anyway.

Kanchan,
  I suggest you recheck what you did. Others have been able to reproduce it.  
  I set up a test tree on Ancestry with instructions as above.  It only fails on the 64 bit version, not the 32 bit version.
  I just retesting it on version 44 and still broken.

I was not able to see this problem on my Windows 7 x64 bit machine at all with exactly the same steps that were mentioned in this bug. I checked again on Windows 10 x64 box and I could see the problem with the released version (44.0.2) of Firefox when I used Ancestry.com's advanced uploader tool. However, I made some changes to the folder options in General and View tabs and then I switched to Ancestry.com's basic uploader tool and things seemed perfect after that for both advanced as well as basic uploader on Windows 10. In order to find the exact change that fixed the problem I reverted all the Windows changes and created new Firefox profile but I could not duplicate the problem again on the released version.

Then I decided to double check on the latest nightly (47.0a1) and observed that basic uploader tool worked absolutely fine but issue could be seen with the advanced uploader tool. I again made the same Windows changes but issue is reproducible all the time now with Firefox nightly using Ancestry's advanced uploader tool and never using the basic uploader or released version of FF on the same machine.

Please find attached the video that shows the issue in nightly and non-existence of the issue in the released version.

One thing that I noticed was the title of the file explorer window. In case of erroneous behavior, it shows "file to be upload by c.mfccreative.com.

Posting this information just in case it is helpful in any way to the developers.

Given comment 5, it sounds like we have a decent idea of what's going on here. Bob, is there anything that needs fixing here on our end? This feels like a Flash issue based on your comment.

Well it's a bit of both, I think.

From what I remember, the difference between the style of the dialog is to do with Flash Player running in our child process or in it's own two processes (protected mode).

However if they started doing what protected mode is doing in our child process (which is where 64-bit flash runs) then I think the sandbox would block it. :(

Ancestry has changed the way they upload media as of today and now, with both 32 bit and 53 bit versions of Firefox, I get the same options as I want.

  Thank you for everyone who worked on this :)
