Flash Player 11.3.300.262 Not working with Firefox. I think I found the problem.

Question

*Flash Player 11.3.300.262 is not working with Firefox. I think I found the problem.*
Millions of people got off work & turned on there computers recently to discover that Firefox is not playing any videos or flash content. Just like me, millions of people are randomly searching the internet in a futile & frustrating attempt at answers. Unfortunately, many of those people will simply stop using firefox & deem it a glitchy, unreliable browser.
This happened to me a couple days ago. I started up my computer & got a pop-up from Adobe saying that I need to update my flash player to 11.3.300.262. I've always thought of adobe as being a reliable software company, so I clicked on it with confidence that things will be working even smoother. To my horror, I relalized that right after the update, my main browser, firefox was destroyed. Then I went on the frustrating process of uninstalling, re-installing, running virus scan, researching the internet like a lost child. I said to myself, "that's why I hate updating stuff, because updates always seem to change stuff you don't want it to change & there always seems to be a problem with the updates." I usualy update software months after it releases, because microsoft & all the other software companies always seem not to test there stuff properly before releasing them. Then we have to look at a glitchy computer until the next update fixes it. Well, that is my rant. Now let me discuss the problem I found.
Problem:
What I did was, go into my firefox extentions menu & I disabled the 11.3.300.262 & I re-enabled the previous flash player. After that, everything worked perfect again. Then a today (a week later), I turned on my computer & my firefox wasn't playing any videos or flash content again. I went into my firefox extenions menu again, & I discovered that my old flash player had been deleted, & this new glitchy 11.3.300.262 had been enabled. Why did adobe feel the need to into my computer & automaticly delete & update my flash player. Now it doesn't work. THIS IS REALY FRUSTRATING!
The Issue I discovered:
"RealPlayer" is the most popular video program & it is installed on millions of computers. For some strange reason Firefox does not want its users to use Real Player. Specifically the RealPlayer Browser Record Plugin 15.0.2. I also discovered that my Browser Record Plugin 15.0.2 was automatically disabled when the Adobe 11.3.300.262 was automatically updated also.
- Maybe this could be because of some copyright conspiracy to keep people from downloading videos from the web.
- Maybe firefox wants people to use there download add-on instead of RealPlayers downloader.
I don't know what ther reason is. But what I do know is Nobody is going to delete there RealPlayer from there computer just to use FireFox. We can simply use Chrome or Internet explorer. I took the advise from Adobe & disabled the FireFox RealPlayer Extention. I also went into my RealPlayer preferences options, But there was no option to disable download recording from FireFox. BECAUSE I ALREADY DISABLED THE ADD-ON in FireFoxes menu.
Solution:
Step 1: Adobe needs to update all the computers with the previous flash player. That way we can choose to enable the previous flash player in our FireFox. or wait until a new update fixes the problem with firefox.
Step 2: Adobe & FireFox need to get together & go back to the drawing board. They need to create a update that actually works on computers that have Real Player installed on them. I don't care which company does the update. All I care about is if it works. Thank You.
Oh yea, Im running FireFox 13.0.1, Windows 7, HP computer, Real Player is up to date.

Hey Chris,
I was able to duplicate this issue on my Windows 7 laptop as follows:
     1)  Completely uninstall FlashPlayer (using your tool) as well as Mozilla Firefox and Mozilla Maintenance Service (used Windows 7 - uninstall from Control Panel).  Please note that I checked the box that said "Remove my Firefox personal data and customizations" to ensure that Firefox was completely gone from my laptop.
     2)  I then went out to the Firefox website and downloaded the "Firefox Setup 13.0.1.exe" app to my laptop.  I ran this app to install Firefox.
     3)  I then went to the following website http://www.ishmael.org.uk/karaoke02.php as I know that this URL uses Flash Player (obviously you can go to any URL that uses Flash Player - I'm just letting you know which one I used).  I then clicked on the icon on this page to install Flash Player.
Once the install was completed, the URL stops responding and appears to be locked up (although it will occassionally hiccup and display portions of the page and then lock up again).  You will eventually get a pop-up notice from Firefox that has the header "Warning:  Unresponsive script" and says the following: 
     A script on this page may be busy or it may have stopped responding.  You can stop the script now, or you can continue to to see of the script will complete.  Script:  chrome://browser/content/browser.js:6551 
Selecting "Stop script" will get Firefox working until you hit another page that uses Flash Player.
To ensure that the above URL is not the culprit, I used one from your website http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html and had the same results.
Hope this info helps!
Jeff
NOTE:  As a reminder, I do not have RealPlayer installed on my laptop (and never have had it installed)
