Shockwave Adobe Flash 10.2.152.32 only plays in one 'user account'

Question

Shockwave Adobe Flash 10.2.152.32 won't play anything imbedded using *my* User Account in WinXP SP3(for ex.: items on HuffPost/none of Hulu/no  streaming radio stations' broadcasts listening functions, eg, 'radioplayer' and 'mediaplayer' in these sites'  windows' addies/ no Vimeo (for ex.: someone streaming a view of a backyard bird's nest). YouTube is not a problem at all.
Firefox 3.6.14 ; 32-bit  OS
Flash stopped working on my "user account" in XP when i updated Flash two days ago March 8 2011 AND then updated to IE 8 (from 6)(which we don't use) and also to SP3 for WinXP (from SP2)(not Pro). All the Microsoft updating took about an hour, maybe longer.
Turning off Hardware Acceleration had no effect.
Uninstalled and re-installed the Adobe Flash Player from Adobe's site.
Adobe plays any and all on the DH's user account, but nothing plays on my "side".
I have administrator status and all that.
Checked many FFsettings for allowing javascript, popups, internet zone medium security, etc.
NoScript to allow all or just the strictly needed, in attempts to diagnose this prob, when on a webpage.
Shockwave Flash in Add-Ons is "enabled" bec I noticed yesterday that it was somehow disabled.
Shut down and restarted three times while allowing it plenty of time to do so properly.
MS Windows Media Player Firefox Plugin 1.0.0.8 in my add-ons, also.
"HTML5 Extension for Windows Media Player Plug-in 1.0" in my Add-ons.
AVG Antivirus Free Edition 2011.
Using Sandboxie; however, I use Firefox without the sandbox and do restarts (and i'm careful to save stuff from the sandbox when closing etc)  when adding.
Turned off the Windows firewall at one point while trying to get video/streaming to play after all my updating resulted in this problem.
Curious as to why the plug-in says "Shockwave Flash 10.2.152.32 with that little 10.2r152 underneath" but the version # i installed refers to *Flash Player* not Shock...blah,blah 10.2.152.32 when I obtained it-- is this just terminology quirks or different things?
Thank you for your time; I read many posts to see if any were like my prob, couldn't find one.

Answer 1

1. NoScript is "NoScript allows JavaScript,Java(and other plugins) only for trusted domains of your choice(e.g., your home-banking web site).
This whitelist based pre-emptive blocking approach prevents exploitation of security vulnerabilities(known and unknown) with no loss of functionality..."
This is an extension, an add-on, for Firefox browser. It is not a plugin. I like it bec I can choose to avoid a type of exploitive code/malware that can ride along
with the potentially large number of scripts that run on web sites (many sites have no scripts attached) and bec it keeps my computer from trying to deal with all those scripts.
2. The "AVG Anti-Virus Free Edition 2011" is stand-alone, not a browser extension. I have a Firefox browser extension that is AVG -- called AVG Safe Search 10.0.0.1178.  The other extensions are ColorfulTabs Plus 4080.04; Abine 0.705; Add-on Compatibility Reporter 0.4.2; Interclue 1.6.1.3; four Java things that appeared on their own(Console 6.0.21,22,& 24, and Java Quick Starter 1.0), as did Microsoft .NET Frameowork Assistant 0.0.0; NoScript2.0.5.1; Organize Status Bar 0.6.4;ReminderFox 1.9.9.2 (calender/reminder); StumbleUpon Toolbar 3.63 (it remains hidden  underneath my navigation bar unless I want to use it, which isn't often). All are "enabled" and updated. 
3. Java versions:  Java 2 Runtime Environment,SE v1.4.2_03; Java 6 updates 2, 24, 3, & 7; Java SE Runtime Environment 6 Update 1.
  Thank you!
p.s. As a last-second re-try of a request made of most people here with FP probs, i just un-checked the Hardware Acceleration box at the Adobe Testsite ("F"
animation graphic) and even though that was *ineffective*  the first time I tried it, it resulted in a seeming solution.  ??  Also, at the site, unlike the last time, the
Pipeline advert appeared when the "F" stopped it's little turn...  I don't know why this was different this time, I just hope this solution "sticks and stays". The first thing I tried was Hulu,and the audio was behind the video, so I stopped that one and went to good 'ol 30 Rock and everything matched up okay. Also, radio stations and the Vimeo hummingbird nest stream (yay!) working. Is the un-checking of Hardware Accel'xn going to cause a problem later, I wonder?
Again, thank you guys and esp the patient "eidnolb"  tons for all the attention and help, and I hope everyone gets their Adobe products all dialed-in quickly and easily. If the hardware-acceleration solution "fails", I'll try here again. I love my computer and the inter-tubes!  Knitterer
