Hello

I use Mozilla Firefox on Windows 8.1, with Adobe Flash Player,

and I get an error while loading a video:

"Video not available".

We have difficulties playing this video.

This has happened on Facebook. On YouTube the videos load very well. I tried all the solutions only Adobe and Mozilla offer in their help the two centers, but nothing is done, videos will not load on Mozilla Firefox. (On chrome and IE the videos load very well).

This happens on both of my computers, one is a new laptop with good material, and the other is an old PC.

Everything is completely updated: Windows, Firefox and Flash player.

And this problem also happens when I opened Firefox in Mode safe mode (without Add-ons or extensions enabled).

I tried unsuccessfully to solutions:

For anyone facing the same problem, my problem has been resolved thanks to philipp of Mozilla support forum.

Put on the link: https://support.mozilla.org/en-US/questions/1069607

Basically, the problem was with the K-lite codec pack.

Uninstalled, and restored the Tweak Tool defaults, and now it works!

  • From 50.0, Firefox will not load the tabs. How can I treat?

    Recently (very probably coinciding with the 50.0 update), Firefox suddenly stopped loading tabs. All the pages get stuck on 'connection '.... "as well as system as topic tabs: support and about: config. Google.com and other Web sites and locations internal intranet do not load.

    The first tab that opens at the start of Firefox will sit on a white page indefinitely, not to load the page speed dial 'shortcut '. Not even the tabs system such as topic: support load. If a second tab is open, and the first tab is closed, then the tabs system become available, but websites will always be blocked to 'connection '.... »

    This troubling behavior began to appear in dozens of jobs in our Organization. On each of them, except one (so far), we were able to resolve by obtaining: support to load using the method described above and refreshing of Firefox, which leads me to believe there is some sort of problem with the profile.

    On a desktop, Firefox seems to work after a refresh, but after an instance of Firefox is closed and a new opening, the new question asserts itself. When you open Firefox under a new user profile, it works once before breaking. On this particular station, I tried uninstall Firefox and reinsert several times without success, as well as facility nightly, which presents the same exact issues as the regular version. I'm stumped on how to solve this problem for the end user. I even tried to run CCleaner.

    Any ideas?

    Hi HaggenIT, can you please try the following and see if it works: enter Subject: config in the address bar of firefox (confirmed the message information where it appears) & search for the preference named browser.tabs.remote.autostart.2. Double-click it and change its value to false.

  • area of Firefox tabs not available click on, not appearing is not on the desktop

    You can disable the bar le/Firefox Menu in Firefox 4 button. You have the menu bar.

    To Toggle the bar menu, power on/off (Firefox Button extinguished/turned on), do one of the following ways to check/uncheck (Menu power bar):

    • Hold DOWN the ALT key while pressing the VTM letters on your keyboard
    • Using the Menu bar: click on view > toolbars, click on menu bar
    • Using the Firefox Button: click on Firefox Button > Options, click on menu bar
  • Facebook and Firefox does not recognize Firefox as my browser. Cannot install Firefox Add-ons.

    This all happened all of a sudden in itself. I have not installed new programs or software of any kind. I have Norton Security software, but it was installed on my PC for 6 months without any problem. I uninstalled Firefox3.6, 10. And reinstalled it, but this does not solve the problems.

    The user agent string may have been changed, try resetting as shown here - sites say that Firefox is obsolete or incompatible, even if it's the latest version

  • Firefox does not allow Silverlight to run Netflix content on my browser after the most recent Microsoft update.

    The Netflix support rep said that I now need to remove Firefox for 64-bit operating system and install Firefox 32 bits, which I don't even think is possible. I have Windows 7 Pro 64 bit. Netflix was working fine until the update of Microsoft ran 36 hours ago. Now only Internet Explorer run Netflix content successfully. I uninstalled and re-installed Silverlight, rebooted my PC and no dice.

    As for the 32-bit Firefox version you already have: 39 of Firefox is not available in a 64-bit version, at least not officially.

    I think that your Silverlight is a different version of mine. Could you visit the Microsoft test page and see if he says you're good?

    In addition, what kind of error do you receive when you try to access Netflix on Firefox? Details would be useful.

  • Firefox will be available for IPAD and IPAD Mini soon?

    I am very surprised that a great browser such as Firefox is not available for download on the App Store or on your website for IPAD & IPAD Mini. I already installed on my Mac. Is this a site or you do not plan for Firefox become available for download on IPAD & IPAD Mini? Please let me know - thanks.

    Phillipp said, Mac does not use iOS, they are running MacOS and Firefox can be downloaded and run on them. (iPads, iPhones, iPods) iDevices running iOS, which is very restrictive strategies to reduce competition with the Apple software.

  • Satellite T130 - 10G: Firefox does not read any video or flash content more

    My Firefox does not read any video or flash content more. And in watching the news of repair troubleshooting/malfunction in Firefox under graphics, he said that "Direct2D activated" and 'WebGL Renderer' have been blocked because of the version of the graphics driver.

    I downloaded a new version on the Toshiba site, but an update of the driver can not find the new version.
    I had briefly solved the problem by installing the new driver from the file but it is not recognized in Device Manager.

    Automatic update through Windows just tells me that the driver is up-to-date.
    I have the Satellite T130 - 10G.

    Would be great if someone could help.

    Thank you!

    Hmmmm... as you know Toshiba doesn't support third party software so I think that your question has nothing to do with Toshiba directly.

    You find the same content with other browsers?

  • I have 3 short videos I tried emailing stuck in Outbox of my iPhone 6. They tried to send more than an hour. I can't delete them, "Change" is not available in the Outbox. How can I get rid of these so mail will stop trying?

    I have 3 short videos I tried emailing stuck in Outbox of my iPhone 6. They tried to send more than an hour. I can't delete them, "Change" is not available in the Outbox. How can I get rid of these so mail will stop trying?

    Can drag you across the message in the Outbox overview to get the Red delete button? It's been a while since I had paste an email in the Outbox, so I don't remember if that's possible.

    IF your account is an IMAP account, try to delete the e-mail on the Mac. Actions sync between devices in IMAP email, so they should be in the Outbox on the server and you should be able to get to them in the Mail from Mac application, use you it, or in a web browser on the server.

    IF this is not possible for some reason, try the mail application to the phone reboots and the closing force force the phone and then try again. Press the Home button twice quickly. You will see small glimpses of your applications recently used. Blow up the Swipe on application brief mail app to close

    To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.
