Firefox 4, Movies, and Netflix no longer working

I found it unusual that the issues that I was having only seemed to happen when using FF4 and above. I tried everything; e.g. reinstalled all drivers, different combinations of legacy drivers, etc, etc.

This morning I realized it HAD to be something with FF. So in FF, under Tools > Options > Advanced, I unchecked the option for "Use hardware acceleration when possible". Everything seems to work perfectly now. BTW, I also have the "Optimize for Video" option enabled in the DisplayLink tray utility.

Now I can calm the heck down and focus on some work.

I'm sorry to say that you didn't fix the problem at all. In fact, this is not Mozilla's fault, it's Microsoft's, but because they do not make the DisplayLink driver, then the issue is with DisplayLink. Disabling accelerated graphics is only a workaround, not a fix. Preferrably, you should be able to use Firefox, or any other application, that uses acceleration in your DisplayLink devices with non-Aero configurations in Windows because this used to work even though it no longer works now.

There's no reason to accept a workaround as a solution. Sure it fixes it only with Firefox, but then that also breaks all acceleration which newer versions of Firefox benefit from.

Well they should get on it or hire some developers who are up to the task. This bug has been around for a while. Having someone from their company chime in and suggest using an Aero theme is ridiculous.

The symptom is with how newer versions of FF are handling hardware acceleration, as opposed to older versions. Maybe they should start there.

Oh, they know the issue and what's wrong because they can tell you that it specifically was Microsoft's fault in one of their updates. The thing is, they've never stated if it's possible to fix or not and if not, why they haven't gone to Microsoft to get it changed. There's no reason the API from Microsoft should fail if Aero is off since some systems can't even use Aero.

It's more important to explain if it's fixable, why it's not (if not), and how long it's going to take. And honestly, I don't believe anything's not able to be fixed or I could just sell off the DisplayLink hardware I've already purchased as it's fairly useless if I can't put applications in any of 'em.

Windows update broke the video in basic mode implementation last month, so video will only work in Aero mode on Windows 7 at the moment.

That's what we were just talking about. And it broke sometime in February to March which is why we're both peeved it hasn't been fixed yet. Not to mention some other bugs which I wholly dislike associated with OpenGL, but I'd rather not go into those because I can't even use the monitors for hardly anything anymore anyway.

Now the issue is much worse with Windows 7 x64 SP1 and IE9. I'll never purchase another Displaylink product again.
