Flash player invisible on some sites with Firefox 4

I have my problem documented on Adobe's forums @ http://forums.adobe.com/message/3589972#3589972 but they have been unable to help me so far and suggested I post the problem here.
At http://www.adobe.com/software/flash/about/ the animation doesn't appear. Neither can I view the global settings panel @ http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager02.html
Similarly, I cannot see the player @ http://www.liveleak.com when I click any of the links. There is just a blank space where it should appear. I can however hear the audio. Neither can I see the player @ http://www.vimeo.com.
However, the animation works correctly @ http://www.adobe.com/shockwave/welcome/ I can also view flash videos @ http://www.bbc.co.uk/news/ and http://www.telegraph.co.uk/ The staged video demos @ http://www.adobe.com/devnet/flashplayer/stagevideo.html also play correctly. Also, I can play flash video on Youtube although I've signed up to the html5 trial, so most of these are in that format now.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

FLASH Player 10.1 NOT WORKING WITH FIREFOX PLEASE HELP!!

Hello I need help with this problem quickly. I have had this problem for the last month and it's driving me crazy.
I am running Firefox 3.6.10 on a 32 bit on Windows Vista I have tried uninstalling and re installing nothing is working. I have read through many post and still haven't got any luck please Help.
Here are some of the things listed on my system32 Macromed flash
FLASH 10K.OCX
FLASH INSTALL
FLASH PLAYER.XPT
FLASHUTIL10K_ActiveX.dll
FlashUtil10_ActiveX
FLASHUTIL10k_Plugin
NPSWF32.DLL
PLEASE HELP THANKS IN ADVANCE

Hi, Just got my Internet connection back! Without knowing what add ons/plugins/extensions you have in FF, it is difficult
for me to say what else may be conflicting.
Other than that, your choices are either Uninstall 3.6.10 and Install a version that wasn't giving you a problem. You could Install the FF beta.
Mozilla has a list of many extensions that conflict with FF if you want that link to look over. One of the other links has to do with other issues that may be helpful.
Let me know and I'll post those to you.
Thanks,

Why is Flash Player still awful at interacting with Firefox?

If I try to watch a 60fps video through flash player on Firefox I can't get the 60fps I'll get something like 30-40. If I try to watch multiple videos that use flash player, flash player crashes.
I don't have this problem with other browsers.
I have GTX 580 and an i7 2600k.

hello, it might be an issue with the protected mode that [http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html adobe has introduced] for its flash plugin for firefox. you could try if [http://forums.adobe.com/thread/1018071#TemporaryWorkaround disabling protected mode] makes a difference.
in case you'd like to troubleshoot the issue further, it would be best to contact adobe's support & file a bug report at bugbase.adobe.com (choose "Adobe Flash Player" as the product & "Browser Integration" as the product area), since they will have a better understanding of the internals of flash protected mode & therefore may know what else might be at the root of the problem you were seeing.

Problems using Flash player 11.8.800.168 with Firefox 23.0.1 ?

I am trying to use Virtual Credit Card Number software with Firefox. I downloaded Flash Player 11.8.800.168 But when I try to open the Virtual Number software it continues to tell me to install Flash player. Any help out there?

Is this Virtual Credit Card Number software a website or a stand alone application? If stand alone, then I would recommend installing the Active X (Internet Explorer) version that you can download here: http://get.adobe.com/flashplayer/otherversions

Flash Player 9 won't work with Firefox-Mac 867 dual mhz

I'm using a Mac G4 dual 867 mhz, OS 10.3.5 and can't get Flashplayer 9 to work on Firefox. I have the 10.3.9 update but can't get it to install. Is the problem the OS version or something else?

Gary,
Thanks for quick response
"First, through IE6, verify your installed version:
http://www.adobe.com/software/flash/about"
Doing this doesn't show installed version, as it does when I
go there from my laptop.
"Can you get to other sites? If yes, does FP work there? If
you couldn't get to the doc's website at all, it's an IE6 related
issue, not FP."
Doesn't work at Adobe either. I can get to the doc's website
but his intro page is a flash video. Get black screen and if you
right click it will say "about Flash Player 9" so I know I'm there
and FP is installed and running
"Many things can be the cause, probs w/IE6 (settings),
AV/IS/Spyware/Adware/Popup blockers, etc.. These can also affect
FP."
I tried checking the IE6 settings per stuff on the forums,
disabled AVG AV and WINXP firewall and none of that helped. Pop-up
blocker says it isn't on.
"I'm surprised that your desktop XP didn't have any FP.
Usually it does have it, but the older versions don't show up in
the Control Panel/Add or Remove Programs list. They're way down in
C:/Windows/System32/Macromed/Flash folder."
Didn't look at Control Panel , just that going to web site
said we needed FP.
"If you can get to the site and ya just can't view flash, try
these things:
Then, go down to the Flash folder and see what's there. You
should have a FlashUtil9x, a Flash9x.ocx, an uninstall file and
maybe a txt file. While online as an Admn User, dbl click on the
Util9x and a "wizard" panel should appear. Follow the instructions.
Close/restart IE, test (go to the site). If no-go, reboot, go IE6
and test again.
Yes, this may get you to FP10, but your IE6 and flash will be
working."
Already did this also, the only "wizard" that comes up either
automatically updates to FP10 or does nothing. In one of your
previous threads you said it would "set" FP. What does that mean
and what screen/button/icon should I be seeing?
Anyway, one of the several times I did it, I let it install
FP10 but it didn't solve the problem.

Problem with Flash player in Ubuntu 11.04 for Firefox

I am running Ubuntu 11.04 on my laptop and use firefox as my main browser.
I have a very strange experience when browsing video sites like Youtube.com or Bumperhit.com
Some videos are playing all right.
But some others, show an error message "Please install Flash Player" etc etc.
I am unable to understand, why this is happening only for some videos?
Also when I try to install the flash Player from Adobe's site, there is no option to save the program.
I would like to save the program, so that I have to download the installable multiple times.
Thank you in advance for your valuable guidance.
Regards
Sujata

Adobe offers the Flash installer as a tar.gz archive and as an rpm archive.<br />
Both files can be opened with a proper archive manager and you can copy to libflashplayer.so to a plugins folder in the Firefox Profile Folder (you need to create that folder) or to another folder that Firefox scans for plugins if you do not want to install the plugin via the software installer.

Adobe Flash 10.1 Won't Operate iSight On Some Sites With Mac OS 10.6

i have Mac snow leopard 10.5, but every time i download the update for 10.6, my adobe flash player (10.1) that operates my iSight cam doesn't turn the cam on with some sites... not all sites... just some. my photo booth application works. it's happened three times now and i've used Time Machine to go back and restore my Mac to 10.5 and Adobe flash works perfect on all sites with that snow leopard version. does anyone know of any reason that would be happening? i've checked firewalls, global settings....everything. i even get the adobe message asking if i want to allow my cam to be turned on, but even when i click yes, it will not turn it on on some sites. the audio works fine... what could be causing this??? thanks.

Hi, the Mac helper isn't on the forum anymore so we depend on other Mac users to help. However, this thread has info on iSight so I thot it may be helpful.
http://forums.adobe.com/message/2871603#2871603
I'm not sure what is causing your exact issue with updating to 10.6 and FP 10.1. Have you tried turning off the hardware acceleration? I'm not sure if that would help, but you could try. I'm not that familiar with Mac either, but not knowing what the upgrade has that appears to conflict with FP 10.1 doesn't help either. It must be something.
To turn off h.a. go to this link and right click on the Flash logo and click on Settings, then Display Settings and UNcheck the h.a. there. http://www.adobe.com/software/flash/about/
I hope you can find a solution.
Thanks,

I've down loaded adobe flash player but when I try to veiw video on firefox I'm still told that I need adobe flash player. How do I get firefox to see the flash player download?

I was trying to view a video I uploaded to facebook using firefox. The system told me to down load adobe flash player. I did but still get the message that I need to down load flash player. How do I get firefox to see the down loaded adobe flash player?

by installing from within Firefox, Internet Explorer has its own version (Active-X).
Make sure you are starting in the correct place for Flash
* http://www.adobe.com/software/flash/about/
If you want to read PDF files in you browser, you might also want
* http://get.adobe.com/reader/
After the download,
#bring up the download manager ("Ctrl+J") and start your installs. As soon as the install comes up,
#close Firefox with '''File > Exit''' or "Firefox" button > Exit. Give Firefox some time to close.
#If install does not proceed, '''terminate "firefox.exe"''' and '''"plugin-container.exe"''' from the "Processes" tab in the Windows Task Manager.
#* Windows 7 shortcut to the WTM is "Ctrl+Shift+Esc"
#* or on any Windows system from "Ctrl+Shift+Esc" then choose Windows Task Manager.
#*Make sure that "firefox.exe" is no longer running -- if it is still running then terminate it by selecting the use "End Process" button or from context menu, and do the same for "plugin-container.exe" if it is found there.
#proceed with the install.
'''Warning''': this is the Adobe site and they have chosen to to provide crapware along with their own product. Only install the product you were planning to install. Do not install additional products: including -- "Free! McAfee Security Scan Plus" or "Google Chrome". Installing Google Chrome on your own and installing it because it is offered on the Adobe site are two different things.
Find updates for your installed plugins at http://www.mozilla.com/plugincheck/ mozilla.com/plugincheck
-- best to use Adobe's site to really see if their plug-ins are up to date.
Please fix your caps lock or read what you type, do you think anybody could read my answer if I typed in all caps.
If the above fails to correct the problem, I would try uninstalling Adobe Flash from your system entirely first, from the control panel then "Programs and Features".

Installing Adobe Flash Player 10.0.42 Plugin for Firefox 3.5.7

I currently have Firefox 3.5.7 installed and am trying to access a site that requires the current version of Adobe Flash Player (10.0.42). When I download and install it, the website still doesn't recognize flash player being installed.
I go to Adobe.com, make sure I am downloading the one for WinXP/Firefox and install it, then it says that it is successfully installed. However, when I try to access the site, and it says that the current version of flash player is not installed, with a link to the adobe site to download the latest version (which I already did).
I have tried uninstalling the flash player, from both Windows and Adobe's uninstaller, and reinstalling with no success. I have even tried uninstalling/reinstalling Firefox, still nothing. For fun, I tried updating IE, and it works fine, but I REALLY don't like IE.
Another note: when I uninstall Flash Player, it doesn't remove it from my machine (add/remove program list), even when Windows asks, "Adobe ... is already uninstalled, would you like to remove it from the list?" Additionally, when I go to Adobe's Flash Player version tester site, it reports that IE is running version 10.0.42, but when I access it with FF, it shows a link to download the latest Adobe FP.

The flash plug in does work with the Crome browser but it will not work with Internet explorer.
I looked in the manage add-ons and it says enabled.
I also went into the safety tab and deselected

Restarted and still does not work.

Chrome uses a different and separate plug-in.
There are things about IE you need to know, especially 11. Specifically:
"User-Agent Strings"
That doesn't mean a lot, I'm sure, but it's the root of your problems, and Flash Player has nothing to do with it.
Microsoft "rewrote" the User-Agent Strings for the abomination they call their latest and greatest browser. User-Agent Strings are what websites use to identify the browser you're using and provide the proper content for it's browser engine, like ActiveX stuff, and Flash or HTML5 video. Thanks to the geniuses in Redmond, WA, the User-Agent Strings for IE11 (which has a Trident engine), ID it as either "Gecko" (Firefox) or "Webkit" (Chrome). Problem is: when the site the directs to the content for one of these two engines, the Trident engine in IE can't intepret it and the site then sees IE as an "unidentified" browser.
The problem with an unidentified browser is that the plug-ins in that browser aren't recognized either, so even though you're up to date, it says you need the latest Flash Player when you use IE11. YouTube... has converted to HTML5 video so if it doesn't detect Flash Player, it can display HTML5 (MP4) video which requires no plug-in to play. Facebook can't do that, because HTML5 doesn't apply to games... only video.
Microsoft has no plans to "fix" the mess they've created because they think it's a great idea to block you out of the websites you visit.
They recommend using "Compatibility View" and pretending that you're using an older verison of IE... Problem with that is that it's seen limited success, and you have to enable it for EVERY page that has problems... individually.
I'm not big on "pretending" so I recommend actually using another browser.
Firefox (from Mozilla)
Opera (from Opera)
Safari (from Apple)
Chrome (from Google)
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.

Possible Work-around: Flash Player 11.5 stops working on Firefox 17

On Windows Vista SP2, Firefox 17.01, and Flash Player 11.3 through 11.5.502.135, I have experienced repeated and consistent error messages saying that Flash Player has stopped working, and with r502.110 Firefox crashed after the first of these messages.
Googling about, I found an old (3-year plus) work-around that some clever people have applied to the current Firefox and Flashplayer, and it works for my problems on my systems:
Edit Firefox about:config, toggling the line “dom.ipc.plugins.flash.subprocess.crashreporter.enabled" from “true” to “false.” Close about:config, exit and restart Firefox.
I do not know what an equivalent might be with IE, since the problem seems to occur there, too.
I do not know whether this affects the FP sandbox, but have found no indication that FP sandbox functionality is affected or security compromised. Adobe engineers would have to answer that.
Also, while they are answering protection questions, what is the effect of disabling Flash Player Protected Mode? This has been a suggested work-around by the staff here, but no one seems to know what the security exposure would be if the sandbox is disabled.

We have a new 11.6 beta available that you might want to try. In addition, please see this FAQ for Firefox troubleshooting steps.
How do I troubleshoot Flash Player's protected mode for Firefox?

Installed flash player 12. All sites report "flash player required, get flash player".

Flash player 11 worked fine - - no problems. Installed Flash player 12; now all sites report that I have no flash player. Flash object add-on is enabled for all web sites. What's going on?

See: http://blogs.msdn.com/b/ieinternals/archive/2013/09/21/internet-explorer-11-user-agent-str ing-ua-string-sniffing-compatibility-with-gecko-webkit.aspx
MS really did a number on IE 11. They intentionally screwed up the User-Agent Strings so it's difficult if not impossible for websites to identify.
The pages can't recognize the browser, so they don't recognize any of the plugins, like Flash Player. So far, Microsoft has made NO indication that they have any plan to fix it soon. In fact, the loonballs in Redmond actually think this was a good idea.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using an different browser. Trouble with that is it has seen limited success at best, and you have to individually enable it for EVERY page that has problems.
I'm not big on "pretending" so I recommend actually using another browser.
Firefox (from Mozilla)
Opera (from Opera)
Safari (from Apple)
Chrome (from Google)
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.

The flash player plugin is correct installed, but firefox keeps asking to install it and then says not possible

I have installed flash player.
The test site of Adobe says it is correct. When I switch it off and do the test the test says "flash player is switched off, press to switch it on" when I dos so the test says that is corectly installed.
When I open the plug-in screen there is no adobe flash player, but only shockwabe flash player, but switching this one on and off had the above mentioned effect.
I have checked the registry (since I could not find anything about flash player in the program list, software in configuration, nor in program files and found that in the windows/system32/macromed/flash directory are the files flashutil9b.exe and flashutil_10uPlugin.exe and some other files, which gives me the idea that flash player is in effect installed.
Nevertheless a flash file in my website keeps asking for the plugin and tells than that it cannot be found.

An example of my website is http://www.vangelder.nl/example
My real website is protected, but the example shows the problem.
I hope you can give the solution.
The big problem is, that since I have these problems (on several computers, working on XP and Vista) I suppose that the visitors on my site wil have the same problem.
I heve been working hours to find out what the problem is, installed different players, used different formats, searched the internet for a solution and I don't want to export this problem to the visitors of my website.

I have a HP Pavillion all-in-one with AMD processor running Windows 8.1 64 bit. Flash Player 16.0.0.235 with all current drivers. I'm consistantly experiencing a green sceen on all Flash Player videos but I have sound.

                                here are the ones that partially worked: the blaze (works on videos that originate from you tube, but not from news stories)
                                                                                          bing (work on videos from their video section - entertainment type, but not from news videos)
the common thing here seems to be that news type videos crash and entertainment type don't. also videos seem more likely to crash on internet portals like yahoo
