Steps to reproduce:


Hello,

Since upgrade to Firefox 40, my website in Flash doesn't display properly some pages (i.e. : http://www.ap-prod.net/#/clients). You can see it during less than a second, and then it is "erased" by a white page. This doesn't occur with IE, Chrome and Safari. Neither previous Firefox versions before 40.

This is a big problem for all my customers.

Hoping a fix from you.

Thank you.

[Tracking Requested - why for this release]: regression since Firefox40

dom.ipc.plugins.asyncInit = false seems to fix the problem

Thank you very much. Do you think this will be fixed for next release?

We should verify that this is fixed in the next 41 beta.

Comment 5

[Petruta Horea [:phorea], Desktop QA]

The issue is still reproducible with Firefox 41 beta 5 under Win 7 64-bit and Mac OS X. Setting the pref to false fixes this.

The error in the web console is: TypeError: swfmacmousewheel is null www.ap-prod.net:101:13, but it is displayed also when the pref is set to false.

Reproduced on Firefox41.0b5 with new profile.

And Reproduced on Aurora42.0a2 and Nightly43.0a1 with/without e10s if set  dom.ipc.plugins.asyncInit = true .

Tracked as it's a regression since 40.

Monitoring the network accesses of that page, I notice that when asyncInit = true, button.xml and diapo_Clients.xml are loaded twice.

(button.xml is returning 404 not found by the way)

Are there scripts in your flash content that control the loading of those files? Is there anything that you can tell me about how those files are loaded?

Also, when I run it under the Flash Player debugger with asyncInit, I see this:

TypeError: Error #1088: The markup in the document following the root element must be well-formed.
	at BannerRotator_fla::Menu_13/SetButton()
	at BannerRotator/SetOptions()
	at MethodInfo-153()
	at flash.events::EventDispatcher/dispatchEventFunction()
	at flash.events::EventDispatcher/dispatchEvent()
	at flash.net::URLLoader/onComplete()

But I don't see that when i run with AsyncInit off.

Can you tell me anything about the code behind this error? Could this be because of the missing button.xml?

Given that disabling async plugin init helps to workaround this issue and the fact that we don't have a patch ready, this will be a wontfix for 41. If a patch is available in the next few days, please nominate for uplift to Beta41.

Right now I think we need more information about what is going on. I'd like some more details as outlined in comment 8.

Is this still an issue ? Works for me with latest nightly in windows-7.

We're not working on asyncinit (and not shipping it by default). Resolving.
