Videos are not working in Firefox

Hey everyone,
This seems to be a common problem, but videos are not working on Firefox, and not just for YouTube. I have updated Adobe Shockwave and Flash, re-installed Firefox, deleted/created a Firefox profile, started up Firefox in Safe Mode, turned off HTML5, checked if any of my plug-ins are disabled, and none of those have helped.
When I get on YouTube and click a video, the video itself doesn't even load. On other sites, in the box where the video should be playing, it says "No video with supported format and MIME content can be found." This kind of confuses me because I have updated the Adobe Flash.
Thoughts? Anything would be appreciated at this point.

Hello,
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. <br/> <br/>[[Image:fpSettings1.PNG]] <br/>
# 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.

  • Javascript "Play Video" button not working in Firefox

    When clicking on "play video" (java), QuickTime will not open while using firefox. It does work in Google Chrome and IE. I have tried using a clean user profile & allowing popups, and I made sure the Java and QuickTime addons were working and up to date.
    The problem is with twit.tv/twit. Clicking the "Live" link on google.com does play the live stream, but the actual Java buttons are not working in Firefox.
    == URL of affected sites ==
    http://twit.tv/twit

    Make sure that you do not block [[JavaScript]]
    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    You can use "Disable all add-ons" on the ''Safe mode'' start window.
    You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

    I have no idea what may have caused your MacBook to stop working, but from your description it kind of sounds like it may have started before you ran Software Update and installed the new Apps. Just the general slow feeling and bugginess is what tips me off. You said that you weren't sure if you had closed all open windows, that doesn't matter if the computer restarts itself. It automatically closes all other open applications when restarting.
    As to your data being retrievable, if when you take it in they do a fresh install of the OS, then no, it will not be unless you want to pay several thousand dollars to a software retrieval company.
    I am glad to hear that you have taken into the Apple Store to get it fixed, and that you have all of your purchased music backed up to your iPod. You should be able to just transfer it all back to iTunes once you get your computer back should it be necessary.
    As a side note, the proper place for this topic would probably in the MacBook forums, not iTunes since there is no evidence that iTunes started the issue.

  • Npapi or webkit plugin are not working in firefox

    I have a Webkit plugin and NPAPI plugin. Both work fine in Safari but just would not work in Firefox (Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3) .
    about:plugins shows it as installed but when I try to access it from html page none of the entry points in a code are being called.(None of trace statement are being hit)
    I think Firefox has problem loading those plugins.
    I have similar NPAPI plugin working fine in Windows environment on all browsers, but MAC is giving me this problem.
    Does anyone has any ideas of what could be the problem?
    I even took a BASICPLUGIN sample for MAC and it has the same problem. Anyb
    == This happened ==
    Every time Firefox opened

    Christofer,
    I solved my problem after not getting any responses.....
    Turns out that some of my xcode compilation switches had to be changed, send me your minimal code that I can compile and i will help you finding it......My NSAPI plugin works just great with all mac browsers....in fact it is the same code excatly as i have for windows, just had to rename some files from .cpp to .m so that I could yuse some cocoa objects....

  • Video.seek() not working in Firefox

    The Video.seek() method does not appear to be working in
    Firefox.
    It works fine in Flash Player 9 and IE.
    I have the 9,115 plugin for Firefox.
    Has anybody else ran into this problem?
    Thanks!
    dustoff.

    Did a little more analysis.
    NetStream.seek() does not work in FireFox if seek() is called
    immediately after NetStream.play().
    This does work in Flash Player 9.
    However, I discovered that NetStream.seek() DOES work in
    FireFox once the video is playing and called via an EventListener.
    Just wanted to clarify.
    However, in Firefox - I do want to show the first frame, and
    then stop.
    So any advice would be appreciated.
    Thanks!

  • Image - maps are not working in Firefox but it does work in IE. Some help required.

    Hey there,
    Last week i've been building a website for our company. However, there is still a problem with our banner/slider. I've uploaded some images and the slider is currently working. But the image maps ,using <map> & <area> taggs, are not functional in FF. They do work in IE so I suppose it should be working correctly.
    I've tried using Chrome & Safari but the problem keeps persisting.
    Some help would be nice (:
    Marnix.

    Doesn't work in Firefox, Chrome, and Safari? <br />
    Sounds like you're using non-compliant code.

    You could try posting the URL to a test case at the Web Development / Standards Evangelism forum at MozillaZine, and see what they have to say. The support helpers over there are more knowledgeable about web page development issues with Firefox. <br />

  • Flash movies made in keynote are not working in firefox

    I have just finished a 65 page iwebsite at
    www.acendedmasterscards.com
    it is a card reading with a flash movie - made in
    keynote for each card. It looks beautiful in
    Safari but in firefox I get a blank white bit
    instead of the movie. Help! I would also love
    comments on the site! Karen.

    I join in the other's congratulations as your site is wonderful. I really enjoy it and I have bookmarked it that I too can post a link to it when I get to an appropriate place in my web building. I will inform you of it.
    I really like what you did with flash and I was trying to do something similar using keynote but I was exporting to a podcast instead of flash and it was never working right. I now thanks to you might try to do it in flash.
    As far as the other browsers are concerned you might ask the question on the keynote forum as well perhaps one of the experts there will have another idea as to why it does not work. In the mean time keep positive thoughts and perhaps safari will become the new ie since it has been released to windows.
    Thanks for sharing

  • Online videos are not working

    I am not able to watch online video through WIFI on my blackberry curve 8900 phone.  Web pages and Images are working fine.
    -Sandeep

    Thanks very much.
    Actually I am trying to play videos from m.youtube.com . 
    1) Google blog says you need a mobile phone that plays streaming videos (RTSP/3GP with H263/AMR). As per blackberry curve 8900 docs these all formats are supported but still I cant play videos. Even I tried other sites , none of online videos are working.
    Any idea what can be the issue ?
    2) Do I need 3G phone that?  AT&T customer supports says you need 3G phone .I am not able to get them as I am using WIFI for browsing.

  • Adobe Plugins are not working for Firefox or Explorer 8

    HI There,
    my firefox and explorer do not open adobe reader files any more.  IN firefox it opens it in a different viewer and when it prints it prints the document as an artifact and the letters are not clear (almost looks like a blurry .jpg).   The plug in is installed but when I go to adobe reader under preferences then internet it says that the program is not available.  I have tried uninstalling and reinstalling acrobat and it still does not work.  I intalled the latest Java thinking that was the issue but still the same.  I can not find a way to delete and reinstall the plugins in Firefox or Explorer.  Are they built into the new Adobe Reader?  

    Can you guide me on how to change it to adobe reader as the default.  I can't figure out where this option is.
    I have to get access to the computer with the probloem to pull up the error message when trying to open a pdf file in Explorer.  I think it says that it can`t find the program or to try shutting adobe down and try again.

  • Flash video has not worked with Firefox browser for years. When will you fix this?

    Anyone who uses Firefox browser (for Windows or for Mac) knows that flash video playback ceased working sometime around Firefox ver 13 and has not worked since.
    The Mozilla people say it is Adobe's fault - instead of fixing Firefox.
    They say roll back to Adobe Flash version 10.
    This solves the video problem, but then, any other services that depend on the latest Flash build, quit working properly.
    This situation leaves millions of Firefox users in perpetual frustration. We can't use our browser of choice to view any web video built with Flash.
    This is so unacceptable. I am unable to understand why Adobe and Firefox don't get together and iron out whatever code incompatibility is causing this.
    I would really like to hear Adobe's explanation for this.

    Uh... I don't know what planet you posted this from, but Flash video has worked flawlessly with Firefox for hundreds of millions of users here on earth, without any gaps since Firefox was still called Mozilla.
    For the record, I have Firefox 28 with Flash Player 13 installed on:
    WIndows XP (SP3-64bit)
    Windows Vista Ultimate (SP2-64bit)
    Windows 7 Ultimate (SP1-64bit)
    Windows 8 Enterprise (64bit-2 machines) 
    Windows 8.1 Enterprise (64 bit)
    OS 0.6.8 Server
    OS10.7.5
    OS10.8.5 
    OS10.9.2
    And I've had Firefox with Flash Player since 2003 on both OS formats. I've never had a compatibility problem.
    I also use Chrome, IE, Opera, Safari and a few other browsers you probably never heard of (like SeaMonkey, Maxthon, Waterfox, iCab, OmniWeb)... Flash works in all of them.
    I'd have to say the problem is with your system specifically, because if it was a Firefox/Flash compatibility problem, there would have been hundreds of millions of complaints about it, for over a decade. That... just isn't the case.

  • Info popups in HULU are not working in firefox now.

    Just recently the info popups in Hulu stopped working ,have tried different settings in adblock ,but it may or may not work. I have not changed any settings and it won't work in safe mode either.

    ''jscher2000 [[#answer-709368|said]]''
    <blockquote>
    Okay, I see, if you hover over some thumbnails, after a brief delay, there is an overlay with detailed information (text, image). Example screen shot attached.
    Based on a quick look, there is an event handler on the entire document body which monitors mouse movement and checks the current target (element below the mouse) to see whether a "hoverbox" should be displayed.
    One script file involved in generating the box is:
    http://static.huluim.com/huluguru/i18n/en-us/application-1685a53a6bc76296280e488084ceb849.js
    Can you load that file?
    If not, can you think of any reason it might be blocked?
    If yes, could you check for errors in Firefox's Browser Console. here's how:
    Open the Browser Console using Ctrl+Shift+j or the Developer menu. At the top, click the Clear button.
    Next, switch over to your hulu tab and reload the page. Switch back to the console and look for errors. These usually stand out based on an X icon in the left or a colored background. Anything sound related??
    If not, click Clear in the console again, and on your hulu tab, try hovering the mouse over a show that should trigger the overlay. Then check the console for any new messages. Anything sound related?

  • Videos will not work in Firefox but work fine in windows explorer. why?

    I tried to verify my plug-in's and all are enabled. I found where was suggested to remove and reinstall Firefox but that did not fix problem either. I tried to change viewer for videos but still no luck. Not certain why Quicktime doesn't work. Note, videos when browsing will not open but everything else works fine. Videos work fine with windows Explorer, but not Firefox.

    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
    *Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
