How can I make my Quicktime plugin work again?

Before installing the Firefox v3.6, my quicktime plugin was working. After I installed v3.6, the quicktime plugin didn't work. I tried to uninstall v3.6 and installed back v3.5, but the quicktime plugin is still not working. How can I make it work again or how to fix this? Thanks.

Is there a way to undo the installation of Firefox v3.6, meaning to remove any traces of Firefox 3.6 installation, because this problem only came after I installed Firefox 3.6.

I'm able to play streaming videos from websites (e.g. http://www.singingsuccess.tv/videos/?vid=251) BEFORE I installed v3.6. AFTER installing v3.6, the streaming video now shows a blue Q with a question mark in the center. I tried to uninstall that version and install back v3.5, but the problem still exist.

Thank you and hoping for your prompt reply. More power.

Re: How can I make my Quicktime plugin work again?

The video on the website you posted requires Adobe Flash, not QuickTime. You must have an old version of QuickTime set to play Flash content, which is why you are seeing a blue Q with a question mark. You need to download and install the latest version of QuickTime for Windows from http://www.apple.com/quicktime/download/

While you are at it, you should update your other plugins. You can go this page to see a list of outdated plugins and update links:

Re: How can I make my Quicktime plugin work again?

The issue I believe is not with the plugins update because all the plugins have been working right before I installed the new version of Firefox (v3.6). After I installed this new version, the problem started... And also, the plugins I have are updated.

What I wanted to know is if there would be a way to "Undo" the installation so as to regain back whatever was there in my Firefox, or is there any way to remove whatever files the installation has saved in my computer.

Anyway, thanks Alice for the information and for trying to answer my problem.

Does http://www.mozilla.com/en-US/plugincheck/ show that QuickTime is up-to-date?

I doubt that the Firefox update has anything to do with your problem with steaming video from http://www.singingsuccess.tv/videos/?vid=251 - That page, like I said, is supposed to work with Adobe Flash, and having an old version of Quicktime can cause the problem you reported.

Are there any other streaming media sites you are having problems with, so that someone can check?

See Troubleshoot and diagnose Firefox problems for steps you can take to troubleshoot Firefox.

If you want to completely remove Firefox (e.g., in preparation for a "Clean Resinstall"), see http://kb.mozillazine.org/Uninstalling_Firefox#On_Windows

You can also try to delete mimeTypes.rdf in the Profile Folder

Re: How can I make my Quicktime plugin work again?

I've tried and checked the links suggested here by cor-el and Alice. Unluckily, still the problem exists... so I'll see what else I can do about it... maybe use Internet Explorer in the meantime until FF gets a fix on this on later FF versions... because the site with the flash content is playing perfectly with IE browser, so maybe I'll just have to do with that at the moment. Additionally, I tested a site with quicktime flash content and it was working. But the Adobe site where they have a sample flash is showing this "Question mark and Q" image. So, hopefully, when FF releases a newer version, I won't face the same problem when I install that new version.

Thanks cor-el and Alice for your patience in helping me fix this problem... I really, really appreciated your help, especially the links you gave. I learned a lot from those after spending time reading those. Thanks a lot! =)

<sigh>

That's because QuickTime is trying to play the Flash content but it cannot.

Sorry I can't help you further but, you did not answer my question, Does http://www.mozilla.com/en-US/plugincheck/ show that QuickTime is up-to-date?

If you have an old version of QuickTime and can't update for some reason, you can reconfigure it in "QuickTime Preferences -> Browser -> MIME Settings" to not play Flash media. See http://kb.mozillazine.org/QuickTime#QuickTime_browser_settings

As a last resort, you can disable the QuickTime Plugin in Firefox, so that you can view Flash content, by going to "Tools -> Add-ons -> Plugins", selecting the QuickTime plugin, and clicking "Disable".

Re: How can I make my Quicktime plugin work again?

Hi Alice. I found out from the link you gave that my quicktime plugin needs to be updated. When I tried to click on update, it showed me to the site of quicktime for downloading and installing a newer version of quicktime (not just a plugin but the whole quicktime including the player). Currently, my version of quicktime is with license (v7.0.3). My question is if I install this newer version of quicktime, will my license still be valid with this newer version or it will become an unlicensed version with limitations to most of the functions of quicktime? I tried to install the quicktime.exe via firefox to update the plugin but it gives an error because the file is not a ".xpi" file but a ".exe" file. Moreover, my current version of quicktime plugin has been working perfectly just before I installed the latest firefox version, so I don't think that my current quicktime plugin is the one causing this issue.

I also tried your other suggestions of disabling quicktime from playing flash content in the MIME settings via QuickTime Preferences, as well as disabling the quicktime plugin in Firefox via Tools -> Addons -> Plugins. But both didn't fix the problem.

So, do you think if I install the new version of quicktime I will still have a licensed version of quicktime?

Thanks for your patience in trying to fix my problems...

Re: How can I make my Quicktime plugin work again?

You actually have to update the entire QuickTime application to get a new version of the QuickTime plugin that Firefox uses.

I don't know what you mean by a licensed version of QuickTime. Do you have QuickTime Pro (paid version) or the free version?

If you are updating the free version, just download it from http://www.apple.com/quicktime/download/ and then install it on top of your current version (no need to uninstall it first).

If you are updating QuickTime Pro, I copied this from http://discussions.apple.com/thread.jspa?messageID=12301362�

Download a free version of Quicktime. Open it and choose Edit. Scroll down to Preferences and choose Register. Once you enter your Registration Key, it will automatically update your version to QuickTime Pro (this is what I just did on my PC).

You could also post a new question in the QuickTime for Windows forum at discussions.apple.com
