Firefox 16.0.2 will not open You Tube with latest Adobe Shockflash 11.4 etc.

Forefox 16.0.2 on MAC OSX 10.8.2 with most current Adobe Shockwave Flash will not open You Tube videos. Photo of video shows, it seems to load, but then nothing happens. I have gone through all the suggestions on your site and spent a great deal of time and still cannot reach a solution. This is very maddening, as much as I love Firefox.

Did you try the solution given in this article?
[[Flash 11.3 doesn't load video in Firefox]] (applies to Flash 11.3 and above) 
'''Solution 1: If you have RealPlayer installed - update it'''
If that doesn't resolve the problem, maybe something here will help (and let us know what you've tried already)

CS2 will not open. Greeted with "Your Adobe Photoshop user name...

CS2 will not open. Greeted with message "Your Adobe Photoshop user name, organization, or serial number is missing or invalid. The application cannot continue and must now exit." I click OK and PS closes. I've been using this regestered copy on this PC (running Vista 32) for years (daily or at least weekly) without problem until today. Any ideas on how I can get it working again? I have disc somewhere? Thank you.

Unfortunately your cs2 disc is no good except for the things such as the goodies or extras that came on the cd, because adobe disabled the activation servers for cs2 products.
You can try this:
(in other words something removed the info from the windows registry)

More than likely though, you'll have reinstall photoshop cs2 using the new non activating installer.
Use just the photoshop cs2 download and serial on that page.

I have used Firefox on my computer for several years. Today, after upgrading to the new version, I was not able to open Firefox. I have tried several times uninstalling and re-downloading Firefox. It still will not open! What is wrong?

I have used Firefox on my computer for several years. Today, after upgrading to the new version, I was not able to open Firefox. I have tried several times uninstalling and re-downloading Firefox. It still will not open! Is the new version not compatible with Windows Vista?

I hope that link points to mozilla.com or mozilla.org
You will have to close firefox.exe with the Windows Task Manager from the "Processes" tab of the WTM since you don't have a widow to close.
The best way to close Firefox is through File > Exit, for those who stuck with the "Firefox" button click on the Firefox button then Exit. It is not perfect but it is a lot better than just closing the window with the "X" in the upper right corner

I updated Firefox and now it will not open at all. The hourglass shows that it's working but then nothing. I went to add/remove and removed mozilla and reinstalled it and still the same thing. It worked fine before I updated.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Itunes document manager pro will not open a document with .cwk extension. It will catch the document then error message states that it cannot open document. Can anyone tell me what Im doing wrong?

Itunes document manager pro will not open a document with .cwk extension. It will catch the document then error message states that it cannot open document. Can anyone tell me what Im doing wrong?

Forgive my ignorance but I have never hear of iTunes Document Manager Pro. If you mean Document Manager Pro, i was able to find that. Back to your problem, have you tried opening one of those files in the iOS iWorks apps? Form the quick read that I did about this, .cwk files can be opened by Pages, Numbers or Keynote, depending on what type of document that it is and those files can be read by Document Manager Pro, after properly saving them. I don't see that you can go directly from the .cwk file in Document Manager Pro without converting them first.
I took a very quick look at the app, so I may be a missing something about its capability.

I am running windows 7. We updated firefox and it would no longer open. I uninstalled it and reinstalled from firefox website. I click on the firefox icon and it will not open. Help please

It installs and I attempted to launch the browser and it never starts. I tried to uninstall, but it says firefox is running. I restart my computer and uninstall and try again. It still will not open after install is complete. Why won't it ever open up? Help please!

Right-click on your Windows Taskbar and select Start Task Manager. Look in Task Manager for processes running that are Firefox-related, such as Firefox.exe or plugin-container.exe. If you see either of those, right-click each of them and select "End process". Then try again to start Firefox in [[Safe Mode]]. 
*If Firefox will start in Safe Mode, select the option you are presented with to disable your add-ons and plug-ins and restart Firefox normally. You likely have a plug-in, add-on, or a combination of two or more that is causing the problem. Because Firefox allows users to customize endlessly, sometimes there can be conflicts between customized items. From the Firefox menu bar, go to Tools -> Add-ons then re-enable them one by one, restarting Firefox after each and testing after each one to see which one or combination of two or more is causing the problem. 
*If Firefox will not start in Safe Mode, make sure you again check Task Manager and end any running instances, then uninstall Firefox and download a fresh copy from mozilla.org/firefox using another browser temporarily. Re-install Firefox (see: [[Installing Firefox on Windows]] for more help ) and try running Firefox again.
Please report back your progress.

All my pdf documents have turned into firefox html documents and will not open correctly

All my pdf documents have suddenly become firefox html docs & will not open unless I go into the folder, right click, 'open with', etc. I haven't changed any of my settings. I think firefox did an update yesterday, however, so I'm connecting it with that, possibly...

Try this:
# Right click your PDFs, click Properties
# Go to the General tab
# In the '''Opens with''' section, click the ''Change'' button
# Select Adobe Reader (or Foxit Reader/Whatever PDF viewer you use)
# Click Apply then OK.
Does it work then?

Is there any possible way to speak to a person about fixing my firefox browser? It will not open and I do not want to lose the information stored there.

My firefox browser will not open, so I can not try most of the solutions recommended. I do not want to lose stored information such as bookmarks and pass codes so would unstalling and reinstalling cause me to lose that information? I need to speak to a person to help with this, but do not know how to go about it. Should I be contacting Norton or Mozilla?

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
:[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Firefox 7 and 8 will not open, I have to revert back to 4 to get it to start

Everytime firefox upgrades it will not open. No error, just no response. this happened on all updates to 7 and now 8. Each time I have to reload 4. The only advice I found was to somehow set the antivirus. I had McAfee. I completely removed it, but no joy. I now run Symantic Endpoint Protection, but it still doesn't matter. I have a Dell D610 running XP Pro 5.1.2600

Firefox "starts" but browser will not open on desktop

When I click to open Firefox min Windows 7, the program loads, i.e., I can see the window on the Aero Bar, but the browser will not open on my desktop. I have redone my profile and that seems to solve the problem for a while, but then the same problem reoccurs. This happened with four different profiles. When I do get the browser open on the desktop, I find a load of error messages in the error console.

Hello Joseph.
You may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal? [http://support.mozilla.com/en-US/kb/Safe+Mode Safe mode] will do it easy, if you can't hope Firefox.

Firefox 5.0.1 will not open, I just upgraded to it.

Firefox will not open. I have been to the task manager over and over and stopped the already running firefox, no help. I just upgraded to the new 5.x.x, and now it will not open ever.

You may need to delete the Firefox program folder before (re)installing the latest Firefox. 
In case you still have problems after installing then check your security software.
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

I've just updated firefox and now it will not open at all. Please help!

I use gmail and a couple of days ago I started having trouble accessing it and in fact any google related site. Apparently my version of firefox was not supported so I updated to the current version this morning but then found that firefox would not open at all. There are no error messages. I have tried restoring my settings to those of yesterday but although my system says I have returned to the old version 3.5.15 it still will not open. I can now only access the internet by using an ancient version of Microsoft Internet Explorer - which is also not supported by gmail. Although I'm limping on I could really do with some help!!

Perhaps give one of the following documents a try:
iTunes for Windows Vista or Windows 7: Troubleshooting unexpected quits, freezes, or launch issues
iTunes for Windows XP: Troubleshooting unexpected quits, freezes, or launch issues

Firefox 16.0.2 will not open You Tube with latest Adobe Shockflash 11.4 etc.
