Porque firefox no muestra imagen al reproducir videos? Poeque firefox no muestra mensaje ni icono de descarga iniciada o descarga fallida?

Cuando intento reproducir videos de youtube o de algún otro sitio en el navegador firefox este no reproduce el video, solamente el audio, otro problema es que al querer descargar videos el navegador me da la opcion para hacerlo pero ya no muestra el icono de la descarga en progreso por lo que no puedo comprobar que una descarga haya iniciado.

You are using the '''first beta release''' of Firefox 4; it is not meant for general public use. Not all plugins may yet be updated. Only experienced testers should be using that new beta release. When using an early beta release of any application, you can expect problems. You can go to the Quicktime site and/or Quicktime forums to see if there is information there concerning the compatibility of your version of Quicktime with Firefox 4.

Just installed the latest Version of Firefox and it wont play any videos or games? Help, so tired and frustrated with this web browser.

I just installed the newest version of Firefox version30. It wont play videos on youtube but i figured out what to do to fix that (change to "never activate" on Shockwave Flash add-on in plugins).
But if i leave that setting on then the game that i try to play on Facebook tells me turn on flash and when i do i still get a blank screen on FB. What do i need to do?
Im sure theres a simple answer. Ive tried at least 6 different things by reading others solutions and they have not worked. I dont get why why im still having problems WHEN I JUST FRESHLY INSTALLED THE NEWEST FIREFOX AVAILABLE FROM YOUR SITE!!
These annoyances are exactly the reason I and many others have left Firefox for Chrome after being loyal for many years. Help please!

Try to set the Flash plug to click-to-play by setting the permissions for Flash to "Ask To Activate" in "Firefox/Tools > Add-ons > Plugins". That way you can activate the Flash plugin when you need it via the Lego block icon on the location bar.
Also, I don't even see Flash listed as installed on Firefox. Are you sure you have it installed? Try downloading it from the below site

I am unable to watch Youtube videos on Firefox ?

I don't know why I am unable to play Youtube videos on Firefox (this problem stated around mid Sept. 2014).
I explored many solutions but in vain. Firefox/flash (I am not sure) is behaving weirdly, I found some solutions on 'Mozilla Support' when I apply these, I am able to play YT videos but after some time (usually after a re-boot) I get the screen "An error occurred please try again Later" and this cycle repeats. I use a public Wifi/LAN of my university and everyone(using Firefox) has the same problem, and everyone noticed the problem at the same time.
Some solutions I tried are:
1. Deleting Cache, Cookies, History etc etc
2. Uninstalling and Re-installing Firefox and flash.
3. I do have the latest version of both flash and Firefox
4. Using Firefox in safe-mode (Sometimes even in safe-mode I couldn't play YT videos)
5. Disabling Hardware Acceleration (though I use a I5 machine with Windows 7 and Intel(R) 3000 Graphics card).
6. Tweaking DNS settings (changed my DNS server address to 8.8.4.4 etc)
7. Degrading to previous versions of Firefox (I used FF 28.0 in Linux worked fine for a while and then the problem repeats itself)
I am confused, I am not sure where the problem is, because I use Linux(Ubuntu 14.04) and Windows 7 and in both of them Firefox won't play YT videos but Chromium/Chrome does. As I said before videos would play for certain time and then they would stop playing giving me "An error occurred please try again Later......". Another observation is there were only 2 resolutions (1020p and 240p ) available and the result won;t change even if I change them.

Hi, first of all Thank you for your instant response.
Yes, I have updated to version 33, Now the problem is not as random as it was before. I found that I have absolutely no issues when I use FF for the first time after starting my computer. At this point there is no issue at all I can watch videos when both logged-in/logged-out and also they work perectly if I switch between flash and HTML5.
But as soon as I restart Firefox I cannot watch the videos at all. No matter if I am logged in/logged out, I did try HTML5 but still it didn't work. The error message was same in all the cases "An error occurred, please try again later".
We are secured by "Cyberoam" so I don't have access to proxy sites.
By the way these observations are for Windows 7.

Updated my mac to mountain lion 10.8.3 and now my app store, mail or facetime won't open. Also, I am not longer able to play videos through firefox. I tried downloading the combo for mountain lion and it refuses to install? Can anyone help me?

updated my mac to mountain lion 10.7.8.3 and now my app store, mail or facetime won't open. Also, I am not longer able to play videos through firefox. I tried downloading the combo for mountain lion and it refuses to install saying that I need to see developer. Whenever I try to open my appstore, mail or facetime it says that the programmes need to be installed and might not be compatible with this version of mac operating system. Can anyone help me?

It's not a bad install of Mountain Lion. I've had the same thing happen to me, but it affected not only Mail, but a variety of other programs including iPhoto and MS Office, where I had to delete preferences, caches, and reinstall the OS as well as the program itself. I'm still having issues with Mail, so I've gone to another program.
Everything was fine upon the initial install. I restarted my iMac about two weeks after the install, and that's when the issues began to happen. I've reinstalled Mountain Lion twice, but the same issues arise.
As I mentioned above, you'll need to figure out which preferences are causing the issue, then reinstall the program, as a fresh reinstallation will do you no good unless you wipe the drive completely.
Here's a thread that helped me with iPhoto:

My Mac keeps crashing (whole system) when I'm watching videos with Firefox, any idea why?

Ok so I got a new mac and as usual install firefox which is my favorite browser, suddenly my computer started crashing, not just firefox the whole system froze and I had to reboot to make it work again, I didn't know what was happening until I noticed that said crashes happen when I was watching videos on firefox, I tried to use chrome and the issue was gone. So anyone has any idea why this is happening? I really would love to start using firefox again!

Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. [[Image:fpSettings1.PNG]] 
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
Does this solve the problem? Let us know.
If this does not fix the issue, you may need to reinstall Adobe Flash Player on your computer.

How do I get rid of the Annoying Video from Firefox Flicks that pops up on my homepage?

Hi,
You can update Firefox and check: https://www.mozilla.org/en-US/firefox/new/
If the problem persists you can then Reset Firefox and start afresh.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
If you have security software (antivirus, firewall etc.) installed, after updating Firefox you may also have to delete all existing instances of Firefox and its related processes/files in all the different configuration modules/areas of the security software like process monitoring, sub/spawned process control, virtualization, HIPS etc., in addition to the security software's main configuration panel. Instead create new fully allowed/trusted rules for Firefox + its related processes in all the different modules/panels - a genuine/original Firefox installer as well as all the installed EXEs (Application) and DLLs (Application extension) are digitally signed by Mozilla Corporation (right-click > Properties > Digital Signatures). Even otherwise, some security software may also ask again when Firefox and/or its sub processes are started, and you may be able to allow/trust at that time.

[Solved] embedded videos in firefox take a lot of CPU time

Playing embeded videos in Firefox take a lot of CPU time. Actually my old computer is not able to play these videos correctly if they are in HD. The problem appears with flash videos (not so surprising, flash sucks...) but also with html5 videos (there is an option in youtube to turn that on). However if I succeed to have the direct URL, these videos play perfecrtlky fine in mplayer using not more than 10-20% of CPU time. Is there a solution to that? Is there any possibility to use an external player to play HTML5 videos in firefox? If anybody knows, Why this problem, are the mozilla folk aware of this problem? (Note that I posted a thread a long time ago for this problem but concerning flash only)
Last edited by olive (2012-04-27 20:33:59)

There's not much you can do to make HTML5 videos as fast as Xv, see http://swfdec.freedesktop.org/wiki/FAQ. They are slow for the same basic reason as Flash... the video overlay cannot be used because the standard allows for controls and CSS to be rendered on top of the video.
As for redirecting to an external player... this is not as easy as it could be. If the videos appeared in <embed> tags or <object> tags, one could use Mozplugger, Media Player Connectivity and other programs, but I don't think one has been written to handle the <video> tag. An upcoming update to firefox will make it use gstreamer, however. If this still results in slow playback, it will at least make it easier to use an external player. I imagine you would have to patch firefox to make it use a port on the localhost as the video sink instead of the screen. Then you would run gst-launch to receive that RTP stream.

When i open a youtube video in firefox it immediately shows that whole video is streamed when it is yet to stream fully

I am using Firefox 3.6.13. When i open a youtube video in firefox it immediately shows that whole video is streamed (the progress bar shows red instead of grey). But the whole video is yet to be streamed. The information of how much is streamed becomes unavailable.
Listing 2 of the problems encountered because of this
1. Unable to estimate how much time I have to wait before the video is fully streamed
2. Cannot go forward or backward in the video in the streamed part.
(This problem does not occur in IE. I tried the link given below)

I think once I did not even see the page in my history

I am unable to view some (but not all) videos in Firefox. But I can view ALL videos when I use Internet Explorer. Please help. I do not want to use IE.

as stated, I am unable to view some videos in Firefox, but I am able to view them when I use Internet Explorer. How can I view all videos when using Firefox. Thank you.

That is Flash.
You do have the Flash player installed according to your More system details list, so Flash should be working.
*Shockwave Flash 10.3 r183
*http://www.adobe.com/software/flash/about/
Start Firefox in [[Safe Mode]] to check if one of the extensions 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.

Ff no reproduce video en Android 4.4. Ff doesn't play video in Android 4.4.

Hola. Tengo una Samsung Galaxy Tab 4 con Android 4.4 Kit Kat.
Es imposible ver videos en Firefox. En otros navegadores los videos se ven bien, pero no en Firefox. De ninguna versión. Ahora mismo tengo Ff37, pero el mismo problema existe en todas las versiones anteriores.
He deshabilitado todos los plugins y complementos y el problema persiste.
Gracias por su ayuda.

It is impossible view any video in Firefox. In other browsers, videos play ok, but not in firefox. None version. Right now, I have Ff37, but the same issue appears in all previous versions.
I have disabled all plugins and add-ons but the issue is still there.
Thanks a lot for your help.

Hi there
First, please report it to Adobe using the link below. But I'd have to say I'm inclined to believe the issue is likely on the Android side. I mean, since it seems fine in one browser and works.
