I'm a big fan of Firefox. I love the plug-ins. I love the community. I love the fact that it's not MicroSoft (I have a love / hate relationship with MS).
Probably my biggest irritation with Firefox has been when I try to watch video clips online, and I get error messages telling me Windows Media Player needs an up-date. Then when I click to up-date, I get more error messages.
Of course, I should've googled this the first time it happened, but I didn't. I've ignored it and procrastinated, continuing to love Firefox despite this one problem.
Well, I finally googled it and fixed the problem! If you've been having the same problem with Firefox playing nicely with Windows Media Player, you'll be happy to know it's a VERY easy fix.
Here's the download link to get the file you need.

The instructions are on the download page, but in a nutshell... download the plug-in, close all browsers, double-click on the plug-in you downloaded, and watch it self-install. You're good to go. Re-start Firefox and test it on a Windows Media video. If you haven't seen the video of Jon Stewart creaming Jim Cramer then I suggest you watch it as your test.
