Cannot play videos using FireFox, but they work in Safari?

I am attempting to play some videos from my schools student extranet. The videos play with no problem on Safari, but not on FireFox. Anyone think they can walk me through a solution? I would greatly appreciate any assistance!

I can't attach a file in Gmail using Firefox, I can attach files when using Chrome and Safari, so it must be Firefox.

Shockware flash is unresponsive and I cannot play videos on firefox..Please help???

I have a constant problem with shockwave. I have shockwave flash 15 plug in installed and am using FF 33.0.2
I constantly get a message that shockwave flash maybe busy or may have become unresponsive. It completely freezes up my Firefox. So I cannot watch any videos using Firefox.
Everything works perfectly on Chrome.
I have tried all the solutions previously suggested such as disabling hardware acceleration but nothing helps.
I am ready to absolutely ditch Firefox..... This is so frustrating..

Does it make any difference to disable the protected mode feature? The feature has security benefits, but is not compatible with all systems for some reason. You can disable it by creating or editing a settings file.
The following pages/posts provide different approaches for that:
* Adobe support article under the heading "Last Resort": [http://forums.adobe.com/message/4468493#TemporaryWorkaround Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]
* Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209
* Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078
You may need to exit and start Firefox up again before this takes effect.
Any improvement?

Hello Pam.
Go into Tools > Add-ons > Plugins and see if Flash is installed. If not, install it ( [http://support.mozilla.com/en-US/kb/Installing+the+Flash+plugin] ). That should let you watch YouTube videos.
If you already have Flash in your Firefox, make sure it's up to date. If it is and it still doesn't work on YouTube, 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, except Flash (just to check), to see if Firefox goes back to normal?

Hulu wont play videos on firefox but work fine on IE; flashplayer on youtube worked after html5 switchover, same issue for hulu videos?

Recently updated both firefox (version 27) and flashplayer plugin (12) and I then started having problems trying to play videos on youtube or hulu. After messing about with troubleshooting, I got the youtube videos to finally play (apparently, had to change to HTML5 mode) but now I still can't play the hulu videos. Hulu works fine on IE (which I used to use before FF) although, that is the ActiveX version of flash player. I've tried most of the suggestions that are out there for this particle problem and none of them seem to work. What I have yet to try is fixing the mms.cfg file located at C:Windows/System32/Macromed/Flash and that's only because my equal sign key isn't working.smdh. The file that was there initially couldn't be opened or was corrupted so I'm thinking this might be the game changer I'm looking for. Any other relevant suggestions would greatly be appreciated as well. Thank you

oh, there is still a pending issue with youtube unfortunately. I can play videos individually but if I click on a video that is part of a playlist it lags and then goes to a blank space where the video should be. Is that a flash player issue? So, I can play videos individually but not playlists.
Any word on that would be awesome
Thanks again

After trying all procedures I can find in Flash Player Help I still cannot play videos on Firefox, I

I am running Windows 7 64-bit and have tried every procedure I can find, and I still cannot get video on any browser.

Do you mean you can not play video but you can play game or other Flash contents?
What about version info page which is extremely simple Flash contents?

I recently upgraded my Mac to OS 10.6.5. Now the links in my incoming emails will not open in Firefox, but they will in Safari. What do I do?

there is nothing more to add.... links from a wide variety of sources simply do not open up firefox and open the website like they used to. I can copy the links and paste them into firefox and they will open.

this answer does not help at all. It tells me how to change my mail client for outgoing mail. I use iCal from mac, which is the default mail program, and it works well for me. The problem is with INCOMING mail that contains clickable links that will not open the page in firefox. When I click them nothing happens. iCal and Firefox used to play together just fine; now firefox doesn't answer when I click a link sent to me and received in my iCal.
Thanks for your help.

CallExternalInterface perfect in Firefox , but not working in Safari?

I finally figured out how to implement the callExternalInterface code. All works perfect in Firefox, but when I test in Safari, I get nothing. Any ideas at all would be helpful. Below is the code...
callExternalInterface(movieVars)
//appended url might be something like....
//index.htm?movieVars=deepLink&movieVars1=residential&movieVars2=theRest&movieVars3=anders on"
function callExternalInterface(movieVars, movieVars1, movieVars2, movieVars3) {
    getMovieName("myMovie").callPlayBall(movieVars, movieVars1, movieVars2, movieVars3);
function getMovieName(movieName) {
    if (navigator.appName.indexOf("Microsoft") != -1) {
        return window[movieName]
   else {
       return document[movieName]
</script>
<script>
    function getQueryVariable(foo, foo1, foo2, foo3) {
      var query = window.location.search.substring(1);
      var arrayHere = query.split("&");
      var param0 = ""
      var param1 = ""
      var param2 = ""
      var param3 = ""
      for (var i=0;i<arrayHere.length;i++) {
        var pair = arrayHere[i].split("=");
        if (pair[0] == foo) {
            param0 = pair[1];
        else if (pair[0] == foo1) {
            param1 = pair[1];
        else if (pair[0] == foo2) {
            param2 = pair[1];
        else if (pair[0] == foo3) {
            param3 = pair[1];
      } //-- end of for loop
    //alert("p0: " + param0 + ", p1: " + param1 + ", p2: " + param2+", p3: " + param3)
      callExternalInterface(param0, param1, param2, param3)
</script>

Java is not working with Firefox (but is working with Safari)

My computer is showing that Java is not enabled via Firefox. When I try to go into Tools/Add-ons, I see that there is no Java plug-in on that list (though I previously had no problem with Java). When I run software update on my Mac, it tells me my software is all up to date. Not sure what else to do. Java is working in Safari, so the problem is clearly with Firefox. I've tried disabling all my plug-ins, and clearing my cache. Nothing has helped.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2.
There will be fix for this in Firefox 6 or in Firefox 5.0.1 if that version will be released, so that Firefox will find the plugin again.
I don't know if all Java applets will still be working on OS X 10.5 with this fix (Apple recommends updating to OS X 10.6).

Again I ask why can I not play video using Firefox?

Firefox will not allow me to play any kind of video. It just won't play since I did the last update. I'm not a good computer fixer upper. So I need simple, easy to follow instructions.

hello brpstcmo, you could try to [[Reset Firefox – easily fix most problems|reset firefox]]...

-Restore from backup
- Restore to factory defaults/new iPod

I cannot play video on safari but works fine on google chrome? What do i need to do to fix it?

If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. Safari > Preferences > Extensions
It can also be installed as a plugin in /Library/Internet-Plug-Ins.
Try uninstalling the currently installled Flash plugin (required for most YouTube content) then reinstall new > Troubleshoot Flash Player | Mac OS
From your Safari menu bar top of your screen click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now from the menu bar click Develop > Empty Caches
