Hi,

I cannot get YouTube videos to play in my desktop's Firefox browser. I'm running Windows 7 64-bit with Firefox 24.0.

I have searched for solutions to the problem, and tried all of these:

-Completely clearing my cache -Disabling ad blocking software on youtube.com -Installing the latest version of RealPlayer -Installing the latest version of Flash Player

None of these have worked. Every YouTube video I load just displays a large black rectangle.

What should I do?

Hi, Since I've upgraded from FF 23.0 to FF 24.0 I am unable to change the video quality in Youtube to HD. The video plays on the default low quality setting, but if I change it to 720p or 1080p a black screen appears and it won't play. When I hover the cursor over the play bar at the bottom of the image I can see live stills of the video.

Things I have done or determined so far:

(1) Problem started with FF 24. Which had the same addons before the problem started.

(3) Started Firefox in safe mode with all addons disabled. Problem is still present.

(2) Opened the same videos in Internet Explorer 10 and I am able to play the videos fine in any available Hi-def setting. So I'm guessing this means it is not a computer problem, or Flash problem.

(3) Updated Shock flash to Version 11.9.900.117 (after step 2). The problem is still present.

Any help would be much appreciated.

Firefox has stopped letting me open a new tab. If I click on the plus sign, hit Ctrl-T, or go to File>New Tab, nothing happens. The only way a new tab will open is if I click on a link in an email, then it opens the link as a new tab. I use tabs frequently and it's very annoying to have to go find an email with a link just so I can open a tab. It doesn't matter if I have only one or several tabs open. I haven't installed anything other than Firefox and Windows (I have Windows 7) updates. I am running Firefox 24.0 but the problem started with the earlier version.

Recently I have noticed that when I go to access my outlook email accounts the password is already filled in by something much longer than my password (I only see the dots, as expected). I want those erased, but don't know how to 'remove' it. I can manually erase them and input my password and it works fine. How do I stop those 'automatic' passwords?

After Firefox auto updated to version 24.0, it has been consistently crashing. I tried unchecking "Use hardware acceleration when available" and making javascript.options.baselinejit.content, javascript.options.baselinejit.chrome, and javascript.options.ion.content false but that did not solve my problem. I don't want to have to switch to a different browser but I can't get anything done with how often Firefox is crashing.

Forced to use the windows 2000 OS. By release date 24.8.1esr is identical to 31.1.0esr (not working on w2000) and close to 32.0 (newer than 28.0) So, between 28.0 and 24.8.1esr, wich is: - faster - safer - less resources - better rendering - accept more new addons/extensions/plugins - has better chances to become obsolete (die) the latest

I an stucked on windows 2000 for an undefinite period in the future and I wish to be able to use the best browser Firefox has to offer.

I use the PORTABLE VERSIONS, at some point, I could share the same profile between 28.0 and 24.8.1esr. I guess they can share alternatively the same files in the profile folder ?

Today, after updating my PC to windows 8.1, I noticed that the minimize, maximize and close buttons have disappeared from my browser. There is an empty blue box in the upper right corner now, with no functionality. How do I get my buttons back?

I'm trying to use Google Drive through my gmail account on Firefox.

When I click on the Upload button my only option is to "enable folder upload...", I click on that and get this message, "Enable folder upload Your browser doesn't support the uploading of entire folders. We recommend that you use the Chrome web browser instead, which supports folder upload. Alternatively, you can install a Java-based Folder Upload applet in your browser." I also get the option to "Download Chrome" or "Install Applet", and when I click on install applet the message "Java Applet installation failed" appears after a few seconds.

I'm running OS X 10.8.5, Both Firefox and Java are the latest version and enabled. I've gone into Java settings in System Preferences and made sure it was "enabled", I deleted the temporary files folder as well, I also cleared my cookies, cache and history in Firefox and restarted.

I don't know what else to do, please help, I don't want to install Chrome. Thanks, N

When I try to use google street view in firefox v. 24 for linux, I get a balloon saying that I must have flash player 10 or higher. I tried to install the lastest version of flash. When I restarted firefox it said it was installing new plugins, so it seemed to notice that I had updated flash. But I still get the same message when trying to view content that requires flash plugin. I copied libflashplayer.so to every plugin directory that I could find on my system, but maybe I still don't have the right one. Where firefox expects to find plugins does not seem to be documented anywhere.

Where is the setting in the FireFox browser for speaker volumn? In the last 2 days, I have not audio while on the internet. Something changed some of my settings and I don't know where to change them back. Thanks!

I use Firefox for my browser. On Firefox, I usually look at youtube videos, and I like to have high-quality video streaming, which Firefox usually allows me to have. But as of recently, whenever I load a YouTube video and try to change the quality, regardless of where i am in the video or how i am changing the quality (changing quality to higher or lower has same effect on video) , the video will go black, the audio will stop and it is obvious that the video is no longer running. I do not remember when this started but it hasn't been for long, maybe 1-3 months. If I make the YouTube player widescreen and reload the page, the video will default at 480p, but I still cannot change it in this position either. I tried doing this in Chrome, and I can change quality, but I don't feel like using a different browser just to play videos, and frankly, Chrome sucks. I don't know what caused this. I think this is related to the new layout of the YouTube video player.

When I try to google a question I am getting a box that says Google is not a trusted website and to the effect that there is no security certificate, I am only getting this on Firefox, when I use Internet Explorer I can Google without problems

Have installed Java 7 update 45. Have both 32- and 64-bit versions installed from Oracle website.

Works in Chrome.

Firefox 24.0 displays error message stating that the Java plugin has known vulnerabilities.

On the support page there is a link to this explanation from January 2013 which regards Java 7 update 11. https://blog.mozilla.org/security/2013/01/11/protecting-users-against-java-vulnerability/

Does anyone have a permanent fix and preferably an explanation for this?

I know how to allow Java to run once as well as always on a specific site https://support.mozilla.org/en-US/kb/how-to-enable-java-if-its-been-blocked

What I'm wondering is why Firefox still blocks Java per default when Java has been updated many times since the explanation was written.

Thanks a bunch!

I have recently switched to Firefox from Google Chrome, and I am finding that I am unable to open any pdf files from the web in any way in Firefox. I cannot download them and open them in Adobe Reader, and I cannot preview them in Firefox, nor can I use the Adobe plugin. I have tried to use the solutions posed by users on this site, but none of them have worked. Any time I make a change to settings to try to solve this issue, the change never allows me to view the pdf file, and the setting reverts to the previous setting after the browser has been restarted. I don't care how I view the file, but I need to either be able to view it as a preview or I need to be able to download it.

Any time java is required, for example on the verify java page, Firefox/chrome/IE freeze then crash giving this information. I have reinstalled java, chrome, IE and reset Firefox. Problem Event Name: AppHangB1

I upgraded to Firefox 24.0 a few days ago. (At the same time, I also upgraded to the latest java.) I have a Dell laptop running Windows XP.

After I upgraded, Disqus comment boxes (and some others) no longer appear in my browser. And I don't mean fail to load, that's an old Disqus problem (occasionally). They flat out do not appear.

As a result, I've gone back to using Chrome, which shows them just fine. I like Firefox better than Chrome, but if I can't see comments on my usual sites, it's dead to me.
