The first time I loaded the page I got a plugin crash, and I reloaded the page and then the video played. There was no Fx hang, and no Fx crash.

I can't reproduce the problem as described on a week-old build, nor with the most recent nightly. The instructions above don't mention which type of installation it is (I have the option to install several bundled things).

Mine is: nprphtml5videoshim.dll 1.0.0.0 (RealPlayer(tm) HTML5VideoShim Plug-In)

Aravind, could you include the contents of about:support in an attachment to this bug?

By the way, the plugin crash registered with this ID: b2b68cce-8814-444f-9cde-e2d262101021 which is the same as the ones reported in comment #0

These are stack overflows, i doubt we can do anything.

if gfx.direct2d.force-enabled is true, then the plugin does not crash. if gfx.direct2d.force-enabled is false, then the plugin crashes.

I get no Firefox crash, what crashes for me is the plugin container, which runs the plugins in a separate process as the browser itself.

Confirm. In my Minefield (Mozilla/5.0 (Windows NT 6.1; rv:2.0b8pre) Gecko/20101210 Firefox/4.0b8pre ID:20101210030339) plugin container crashed. After refresh page, video run normaly.

Comment 8

I think this is most likely a plugin problem. I can only reproduce this on 64-bit versions of Windows.  On 32-bit versions of Windows this is not reproducible (at least for me).  Since the plugin is a 32-bit plugin, this is possibly a problem with the plugin and not Firefox.

If someone can provide proof of this failing on a 32-bit version of Windows in Firefox or can provide proof of this NOT failing in a different browser on 64-bit Windows, that would probably disprove my claim.

Comment 9

[u279076]

I was just able to reproduce this on 32-bit Vista -- so it seems like my claim in comment 8 is flawed.  I had to keep reloading the page until it would reproduce (took about 12 tries).

Unable to reproduce using Firefox 3.5.17, so it appears to be a Firefox 4 regression (OOPP related?)

Same behavior on Firefox 10b3 on Win Xp, Win 7/64.

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
