1. The minimum system requirement for Firefox 14 is a Pentium 4 or newer CPU that supports the SSE2 instruction set; then why can my CPU that only supports the SSE instruction set run Firefox 14 just fine? And what if any limitations will I face?

2. Why does QuickTime Player plug-in 7.7.2 play videos without audio in Firefox 14 or Internet Explorer 8? QT 7.7 claims to natively support many audio and video codecs. Does that mean QT 7.7 supports many audio and video codecs and they are included with QT 7.7; or QT 7.7 natively supports many audio and video codecs, but you need to install the third-party codecs you need, or QT 7.7 can't play audio or video in those file formats?

3. Why does the Windows Media Player plug-in "mswmp.dll" not work in Firefox 14?

Note: both the QT and WMP plug-in are enabled and I followed the Firefox troubleshooting steps. Also, the QT plug-in crashes in Firefox 14 about ninety-five percent of the time!

1. Maybe Firefox requires SSE2 just for advances features such as HTML5 support. Or maybe you didn't notice your processor had SSE2 suport, check with CPU-Z your processor features.

2. I have no idea, but you could install a codec pack such as K-Lite Codec Pack, do the videos play on standalone QT executable?

3. Check in about:plugins that it is enabled.

And maybe 2 and 3 have relationship with 1. Maybe SSE2 is required for plugins to work well.

1. Maybe you're right. I'm positive my CPU only supports SSE, not SSE2.

2. Even with the K-Lite Mega Codec Pack (every audio and video codec known to man), QT 7.2.2 the standalone executable or the plug-in won't play video with audio in IE8 or FX14, yet the same videos play in Windows Media Player with audio. All the correct settings are enabled in QT, too. It must be an issue with QT 7.7.2 for Windows. Can somebody confirm?

3. Both the QT and WMP plug-in are enabled. Maybe.
