Videos won't play in Firefox, but play in other browsers

I'm running Firefox 14 with a default setting to Yahoo. All videos that are connected either through a link or directly connected through youtube will not play. I either get a white screen with nothing displayed or a black screen with an error message that says try again later. It doesn't matter if I connect directly from Firefox or from Yahoo. If I open my AOL browser through Explorer it will play all videos.

You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3.

Netflix is lagging (video/audio not matching) in Firefox but not in other browsers

When I open Netflix on Firefox, the audio and video start off in sync but in less than a minute the video falls far behind the audio. I tried it in Chrome and it worked fine, just not in Firefox. I also deleted the temporary Silverlight files (suggested on Netflix's support site: https://help.netflix.com/en/node/219) and of course I've tried restarting the browser many times, but it still doesn't work right. Help? I'm using Windows 8.1 on HP.

Please check your antivirus/firewall settings to make sure that silverlight xml application traffic is not flagged.
*[application/x-silverlight] mentioned: [https://community.mcafee.com/thread/28572?start=10&tstart=0]
Are you using 64bit mode? [http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx]
Try to restart the browser after deleting the temporary files, it may also be the size of the cache. It is also possible to clear the cache for just netflix by going to about:permissions searching for netflix and clicking on "Forget this site"
I do not think that accleration would affect it, but to be sure please try:
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows:
#* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux.
#* In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
#In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Video will not play in IE but works in other browsers

I have a flv video on a page which was placed there using Dreamweaver CS4. It plays in all other browsers I test it in except IE7. (Firefox, Chrome, Safari) Others verify it dooesn't play in IE7 also. Doesn't even play when I test in 'preview in browser' while in DW. Page passes validation. Can't for the life of me see why. Any ideas.
http://www.princetonmarketing.net/new/pmg-production.html

You've got all these references to scripts but I'm certain you don't need them all. Is this an older page created in an earlier version of DW?
<script type="text/javascript" src="swfobject.js"></script>
<script src="Scripts/swfobject_modified.js" type="text/javascript"></script>
<script src="Scripts/AC_RunActiveContent.js" type="text/javascript"></script>
<script src="Scripts/AC_RunActiveContent.js" type="text/javascript"></script>
Try commenting out the JavaScripts running on your page and then systematically re-introduce 1 at a time to see where the culprit is.

I just downloaded the latest Windows updates, now videos online will not work on Firefox but will on other browsers, anyone else having this problem?

After downloading the latest Windows updates I found that I could not play videos on YouTube or at other sites. Switching to other browsers I found I could play those same videos now without any problem. So I did a System Restore to determine if the Windows updates had affected video play using Firefox. The restore point was set to the day before the Windows download occurred. After System Restore was completed I could now play videos using the Firefox browser.
To make sure that the Windows update was the problem, I again downloaded the newest Windows Updates and once again could not play videos on any site using Firefox. System restore was used to again reset my computer to the day before and once again the videos would ow play in the Firefox browser.

Actually your reply took me in another direction and I found this on the Adobe site:
The RealPlayer extension for Firefox, Downloading & Recording, has compatibility issues with Flash Player 11.3. If RealPlayer is installed Flash Player content does not appear. YouTube provides an error message when you try to watch a video.
As a workaround, do the following:
Start RealPlayer.
Click the RealPlayer icon in the upper-left corner and select Preferences.
Select Download & Recording in the left menu and deselect Enable Web Download & Recording for These Installed Browsers option.
Click OK and restart Mozilla Firefox.
Once I followed this I could now again play videos in Firefox.

The sound has disappeared on Firefox but works with other browsers. Can anyone tell me how to fix this?

I was watching a video of a musician on YouTube and all of a sudden, there was no sound. I tried it using Chrome and had no problem. I refreshed Firefox, but still no sound. Can anyone help?

If you have problems with current Shockwave Flash plugin versions then check this:
* see if there are updates for your graphics drive drivers
'''https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration'''
* disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

Sound has stopped for firefox but works on other browsers! Why?

I no longer have sound with the Firefox browser. Sound works for other browsers (Chrome, Safari, I.E.) but not for FF. I looked in options, plug ins, etc. I have done everything I could to get the sound to work again to no avail. This all started after the latest update for FF. Please help>

Hi Skytyler13,
There are a few different things that might be causing your issue. Have you looked at the Knowledge Base article [[No sound in Firefox]]? It has a lot of good information that might help you.
Hopefully this helps!

The bottom bar, which shows the URL, the "lock" on secured sites, etc, is NOT THERE on firefox but is on other browsers. What can I do?

As above, the bar across the bottom, which shows the URL, the "lock" symbol on secure sites, etc., IS NOT THERE on any firefox page I open. It is there on other browsers but I would like to continue using firefox. What should I do?

In Firefox 4 and later you no longer have the Status bar that showed the padlock in previous Firefox versions.<br />
The padlock only shows that there is a secure connection and doesn't guarantee that you are connected to the right server.<br />
So you might still be connected to the wrong server if you make a typo in the URL and someone has claimed that mistyped URL.
The functionality of the padlock has been replaced by the [[Site Identity Button]] on the left end of the location bar.

My gmail Contacts will not load in Firefox, but OK in other browsers Please advise

For months now, in each versions of Firefox, when I open my gmail and click of Mail/Contacts, an''' oops''' error message appears, and the Contacts will not load. However, in other browsers, IE and Chrome there is no problem, so it '''has''' to be a Firefox problem. Please help to solves this.

A Web site won't load properly in Firefox, but will in other browsers, and most other sites load normally in Firefox.

I have intermittent problems with a Web site not loading properly (rather than a gray background with pictures and clickable captions linking to news stories, a page consisting only of text and hyperlinks loads). The page loads normally in Internet Explorer. The problem with Firefox seems to be limited to this one site. I've previously reported it by clicking Help | Report broken Web sites. Thanks for any suggestions

I had this problem. I fixed it by right clicking on the website page and found I had inadvertently ticked "block images from this website". Uncheck this and it's fine!

Java is not running in Firefox, but runs in other browsers.

I am trying to run java in my Firefox 3.6.13 browser.
Java works perfectly in Internet Explorer, but I rather use fire fox.
I have java installed, and it appears in my (about:plugins) page as all enabled.
yet when I go to the java website to detect java, I end up watching the swirling bar go on forever and then it reports I have no java installed.
Every page that uses java appears blank, the page loads around the java perfectly, but its just an empty space where anything java is.
I made sure to check the control panel and make sure it is enabled for mozilla family as well as the next gen java is selected. unfortunatley no matter how many times I uninstall java/fire fox, and re install, Java will not work

The ''' "Search" ''' box isn't going to do you any good, you need the '''Run''' box. There isn't a "file" in the Firefox Program Files folder that you can use to launch the Firefox SafeMode. ''Firefox 4.0 has a fix to get around this problem in Vista and Win7, so you won't have to activate the '''Run''' box.''
See if this works in Windows 7: <br />

I can't access a site in Firefox but can in other browsers even when I copy and paste address. It pulls up a different site.

This is the address http://www.coupons.com/coupons/?pid=16141&nid=10&zid=dt75
It should be Publix Paws coupons but instead it pulls up what is located on http://www.coupons.com/
The site pulls up fine on Explorer and Chrome. I just installed Firefox.

I use babylon as my dictionary and it dosen't work properly with firefox, but works with other browsers!

Babylon as a dictionary has a feature to simplify finding of word's meanings. This feature is using of middle mouse button to click on any word and in any application such as internet browsers to find its meanings, but this dosen't work in firefox 3.6. When I press middle mouse button on a word, it dose not select it correctly or may be select another word. Any solution?

I had this problem. I fixed it by right clicking on the website page and found I had inadvertently ticked "block images from this website". Uncheck this and it's fine!

The source code for my website shows up wrong for title line in firefox but not in other browsers-how can i correct it? My ranking depends on this.

My title line is correct when I check the source code in Google Chrome. Why is it coming out differently in Firefox?

Works here.<br />
I see the same "Accent and English Skills Training for Success" title in Firefox as in Google Chrome although the title tag has a different value: <title>EnglishWorks.us</title>
Is that title set via JavaScript?

No animation or videos will play from Firefox, but other browsers still work fine. I have checked plugins and even updated to the Firefox 14 beta - no fix

As of yesterday no animation or videos will play from Firefox, but other browsers still work fine. I have checked plugins and even updated to the Firefox 14 beta today, but this did not fix the problem.
this problem started yesterday; before then there was no problem.
I have updated everything I can find, and ran a system restore and disc clean.
The problem still persists. What am I missing here?

This happened to me too. This problem started suddenly with no changes made on my part. I had 11.2 Flash version with Firefox 13. I tried updating to the new Firefox, same problem, then updated to Flash 11.3. I even uninstalled RealPlayer.
I read a solution on another forum and it was as easy as clearing my cache. Everything works fine now (even after reinstalling RealPlayer and allowing the download button function).

Videos won't play in Firefox, but play in other browsers
