Flash Player 11.3.300.262 crashes Firefox on Win7x32

Hi everyone.
Flash Player 11.3.300.262 is better from the last one, but I still can’t use it.
It doesn’t work in a computer that I have with windows 7 and 32 bits. The Firefox crashes, Opera and even Chrome don’t work properly.
It works on other computer that I have like, Windows Vista 32 bit (I have to disable Real Player). Other with Windows 7 64 bit.
Regards.

What is the problem with Adobe Flash Player 11.3.300.257?

I tried to update to Adobe Flash Player 11.3.300.257 using FireFox. I get the screen that says "initializing" and that seems to go okay. I am then shown the screen that asks me how I want to handle updates. I choose notify me. Then the download starts. It completes 47% and then I get a message that says Timed Out. Adobe does not seem to have any solutions. I downloaded it fine on Internet Explorer. FF is the only problem

Currently, I don't have any version of Flash installed as a plug-in on Firefox.
On Internet Explorer, I downloaded the 11.xxx - no problem.
The previous version of Flash for Firefox was 10.3.xxx - I was using that until I went to a frequently visited website and it prompted me to update to the latest version.
I began the download.
First thing I saw was the installer started "Initializing." That stopped and then I was ask to select an update method (automatic, notify me, no update). I selected Notify Me. I clicked Next and then download and install started. It stopped at 47% and gave me a Timed Out message. It then said that it was unable to install. I turned off my antivirus software etc. No luck. No message that I can find indicates that it is getting blocked.
One of the suggestions I read was that, if the 11.xxx version did not download and install, then I should uninstall the earlier versions. I did this. Still no success. The problem continues.
Bing Maps: That has been going on for about one year. I cannot get any search results if I type in a location. The map appears for a brief second and then disappears. It is like it is getting blocked but I cannot figure out how. It does not happen on IE. I was using Firefox on Bing maps fine - this was an overnight change.

Flash Player 11.3.300.257 has issues with Firefox 13

Yesterday I did a speedtest on http://speedtest.ziggo.nl. My download value was the same as my upload value so I contacted my provider to see if there was a problem. Discovered myself that the problem wasn't my internet connection but the update of Flash Player I did some hours earlier. On Internet Explorer and Chrome I get normal download values when I do a speedtest, but on Firefox the download value is the same as the upload value. Also I get a lot of 'Flash Player is crashing' popup windows.
I use Firefox 13 on Windows x64. Updated to Flash Player 11.3.300.257.
I uninstalled Flash using Adobe's uninstaller and installed a previous version (11.2) and everything was working fine again. I got normal download and upload values when doing above speedtest. When I updated to 11.3.300.257 again, the download value was as low as the upload value again and besides that a lot of Flash error popups again.
So apparently the Flash Player 11.3.300.257 plugin for Firefox has a serious bug of some kind?

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)

Flash player 11.3.300.257 plays video too fast

Hi
I have just updated to the lastest version of flashplayer 11.3.300.257. Now, all vidoes in youtube and bbc iplayer etc that use flashplayer run very fast and without sound (just like fast forwarding x4).
I am on Windows Vista Business Edition (all updates included)
Browser is IE9.
I have tried a clean reinstall of flash player a number of times but same issue.
I have cleared caches and deleted all history etc via the advanced section of the software.
I have also removed the hardware acceleration. Nothing has helped.
However, if i run in "safe mode" it seems to run at the correct speed. I have uninstalled all recent software updates (such as skype) but still the issue remains. Is it likely to be a conflict issue?
I have tried to install a previous version of flashplayer from the archives page but get an error message 1722.
Can anyone help?
Nigel

For my reference, here's the bug:
https://bugbase.adobe.com/index.cfm?event=bug&id=3217331 - Flash player 11.3.300.257 plays video too fast
In order to get traction on this, they're going to need to be able to reproduce it.
It would be great if you could do two things:
- Provide direct links to a couple videos that reproduce this problem.
If they're on different sites, and based in the US, even better. (Geographic restrictions make it hard to troubleshoot. We can VPN, but that can mask/introduce network and timing problems.)
- Provide the output of dxdiag.exe
Go to Start > Run > and type "debugdiag" no qoutes, then hit [Enter]
Save the output and attach it to the bug above.

Flash Player 11.3.300.265 Crashes when paused video/stream loses focus to a different firefox window

Whenever I have a video or stream in fullscreen and paused and I try and use my other screen for firefox, it will crash.
I have the latest update of flash player (11.3.300.265) & firefox (13.01, also tried 14.0 beta)
EDIT: Forgot to mention that I have hardware acceleration disabled in both firefox and flash.

Hi,
I had the same. Adobe blamed RealPlayer for the bug but that's not true. It's the protected mode. You have to turn it off via editing a file manually.

I'm having trouble installing Flash Player 11.3.300.257

Last week I got an automatic pop up to update Flash Player. I did as I normally do and a little while later I noticed that Flash Player is no longer working on my computer.
My system:
Dell Precision Workstation 690
Windows 7 Ultimate (64 bit)
Mozilla Firefox 12.0
I have full administrative rights on this computer
I can provide other info as requested.
The steps I have taken so far:
The initial update installation appeared to work normally with no hang ups or delays. At the end of the installation Firefox opened to the Adobe page saying the installation was succesful. However, it became clear when I tried to watch video on Youtube and other sites that Flash was not operational.
I went to the Flash download page again and tried the installation again, but had the exact same result.
I checked the Plug-Ins in Firefox tools and it verified I have the latest plug ins installed for Flash Player.
Rebooted the system and tried again. Same result. (I later shut down the system overnight and the next day tried again with the same result)
I found the Flash Player uninstaller and ran that. Rebooted. Installed latest version. Same result as before (Installation seems to complete as normal but Flash is not working).
I tried a clean installation per these instructions; http://forums.adobe.com/thread/928315
I got the exact same result as before.
Throughout the process, including after the clean install, I have checked this page http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
Each time I see the same thing - Under where it says "Can you see the movie below?" I see nothing. No movie and not even a grey box. Just blank white page until I see the box saying "Yes I can" and "No I can't".
In another thread similar to this ( http://forums.adobe.com/message/4421001#4421001 ), someone asked the original poster this:
"What files do you have in
C:\Windows\system32\Macromed\Flash ?
C:\Windows\syswow64\Macromed\Flash ?
Can you also post the contents of the FlashInstall.log files from both these folders?"
In a pre-emptive effort if it helps anyone, this is my answer to that request:

I have never had an issue updating Flash Player on this computer before and nothing of any significance has changed (ie, hardware, software, admin rights, etc). I'm at a total loss and I would appreciate any advice anyone could give.

Flash Player Protected Mode provides a modern, sophisticated set of security protections that we see as critical in today's security landscape.
We highly recommend that users not disable ProtectedMode. Also, it's worth noting that by manually changing your mms.cfg, you have opted out of Protected Mode for all future versions of Flash Player, as we will continue to honor that preference. This puts your system at risk, and that risk will continue to grow over time.
Ultimately, this is an issue with the RealPlayer Browser Record plug-in. There is a more technical explanation in the Mozilla bug referenced above in the thread, but the simplified version is that the security enhancements designed to prevent the introduction of malware via Flash Player make RealPlayer Browser Record plug-in no longer compatible with Flash Player for Firefox. You can disable the record functionality to eliminate this issue, while retaining the ability to view both Flash and Real Player content.
To disable the Real Player Browser Record functionality while maintaining the enhanced security provided by Flash Player with Protected Mode, do the following:
    Launch RealPlayer
    Click the RealPlayer icon in the upper-left corner of the window, and choose Preferences
    Choose Download & Recording from the left-hand menu
    Uncheck "Enable Web Download & Recording for these installed browser"
    Click OK

Adobe Flash Player 11.3.300.257 isn't working properly.

Hi! Ever since I updated my flash player I haven't been able to use anything that uses flash. It just keeps crashing every few pages and lagging. The browser I use is Firefox and my PC is a Windows 7. I was wondering if it's happening to others too and if you're working on fixing it? Or should I just try to download the older version instead?

I'm sorry you are running into this problem with Firefox. If Flash content is causing your browser to crash, at this time I'd recommend reverting back to a previous version. We are hard at work on solving this problem, but we do not have a fix available yet.
How do I revert to a previous version of Flash Player?

Non-responsive scripts after installing Flash Player 11.3.300.257

Adding more info, I do not happen to have RealPlayer installed.
After updating FlashPlayer to the latest version I experienced non-responsive scripts - I use NoScript plugin with Firefox, as well as Java 7 update 4.

Java 7 update 5 has been just released, thanks for replying.
I did not install it though, in order to try to reproduce the problem.
I am a Mechatronics Engineer and I have a non-common OS and software configuration.
There is a numerical simulation application in my system which requires a programming language compiler to run, and such compiler requires the OS primary SDK and framework to be "understood" by the system.
That said, I believe all the debugging routines might be somehow limiting FlashPlayer abstraction layer functionalities.
As awkward as it may seem now, Firefox did not crash after one absolutely random measure I took.
I opened this page: http://www.adobe.com/support/flashplayer/downloads.html and downloaded Windows Flash Player 11.3 Plugin content debugger (for Netscape-compatible browsers) from this link: http://download.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_plugin_debug.exe.
Although there is a hanging before opening the about page and Youtube, flash content is indeed presented.
Well, there might be a different abstraction layer approach regarding this content debugger version.
I wait for further insight from you guys.

After updating to the new flash player 11.3.300.257

Hi,
After i updated to the new flash player, i am facing problems with my flash media, such as youtube videos and flash games, youtube loads very slow and sometimes it loads sound without video. flash games doesn't load at all.
some other video sites, the video area shows all black or all white.
i have followed some solutions that i have found in this site .. but nothing helped ..
what to do ?

Flash has recently updated to version 11.3. Some users are reporting issues with this version of Flash and Firefox. The video may appear black, white or grey and never play. This article has a few solutions that have been reported to work. " http://support.mozilla.org/en-US/kb/flash-113-doesnt-load-video-firefox "
tried all this solutions but nothing worked

Re: Flash Player 11.3.300.257 Keeps Crashing On Mozilla Firefox 13

I want to know if the dev team has tested out my issue. When you load the game Lineage 2 in windowd mode, then firefox and flash site like youtube, it will 100% of the time freeze solid firefox. This is easily eproducable and you need to get touch with NCSOFT about this and fix it. The game is free and u don't need an account to make this issue happen. Just install lineage 2 www.lineage2.com and runt he launcher app then load lineage 2. When the logon box pops up this is the death point. Press alt+ enter fopr windowed mode. Run firefox and a flash site. BOOM. Totaly frozen.
I think the GAMEGUARD anticheat system included with this game is somehow interacting with the new flash somehow. So work with gameguard and ncsoft to get this fixed.
I expect a follow up on this issue as I have already stated this about 1 month earlier with no response.

Thank you Duhmez,I have followed the instructions at
http://support.mozilla.org/en-US/kb/flash-113-crashes
Hopefully this will work with Firefox...then I will try Chrome & I.E. 9 to
see if I have similar issues....thanks for your response...Doc

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

*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)
