I'm unable to play videos of any sort in Firefox (YouTube, Vimeo, etc.). I've installed the latest version of Flash multiple times and I've downloaded the latest version of Firefox. I've also tried disabling Adblock and clearing the cache/history, but nothing works.

For whatever reason, youtube will no longer work in my firefox browser anymore. Every time I try to play a video I get a message saying "An error has occurred. Please try again later." I have tried running firefox in safe mode, but that didn't help. I believe it stopped working after I installed the newest version of Java. So I even tried uninstalling it, but that did not work either. I have the newest version of adobe flash and firefox, so I have no idea what is causing this problem.

I click on the rotating balls of download helper and it looks as though the download is taking only a couple seconds. Then, when I click on it to play it it doesn't work and says, The document “Barney_ I Hear Music Everywhere.mp4” could not be opened. The movie's file format isn't recognized. To see if additional software is available that will enable QuickTime Player to open the movie, click Tell Me More.

I have a 2011 Apple Macbook Pro 13".

Any help is greatly appreciated.

Thanks,

Luke Wilson

As someone who deals with video media on the web quite often, this handicap inherent in Firefox is a fairly big and ridiculously obvious problem. When, if ever, will it be resolved? If Firefox wasn't such a popularly used browser, this issue wouldn't be as much of a concern, but people are using Firefox quite a bit on-line. It seems very strange to me that this otherwise excellent browser from Mozilla can't play back a simple MP4 file in HTML 5.

"Firefox doesn't support MP4 and 3GP due to their patent-encumbered nature."

Is there a way of resolving that at any point? If not, is there a reliable format that I should switch to instead of MP4, like Flash? I'm aware that there are plugins available to make Firefox "see" MP4 files, but asking customers to download and install a plugin is not really a professional solution. Please advise! Thank you.

This has started happening since the last Firefox upgrade (to 14.0.1). It affects two machines - one running Windows 7, the other XP. The symptoms are identical.

Firefox is the default browser on both machines. I'm using only a default profile on each machine. I've checked that there are no stray "no-remote" switches in the command line or environment variables and I've tried deleting "parent.lock". The fact that it has happened to two separate installations, as a result of the upgrade, and the fact that all other functions of Firefox work as expected, makes me doubt that it's a profile corruption. I have also tried opening Firefox in Safe Mode but the behaviour is the same.

Here's what happened/happens:

Previously, if I had opened Firefox in the normal way from the start menu and then clicked on a link in an email in Thunderbird, the link would open in a new tab in the running copy of Firefox. I could do this with multiple links, each opening a new tab.

Now, if I do this I get the "Firefox is already running" error box.

If I close Firefox the click on a link in an email in Thunderbird, it will start Firefox as expected, and open the link. But if I then click on a second link, I get the error message.

If I click on URLs in other applications (for instance Pidgin instant messenger), the links open in new tabs in the running Firefox in the usual way, so the problem seems to be specific to links opened in Thunderbird.

As an experiment, I rolled my FF installation back to 13.0.1 on the XP machines. Everything then worked as before, and as expected, so this is clearly to do with the upgrade.

I tried the two methods I've heard so far to disable the new firefox 19 pdf viewr: -in about:config set pdfjs.disable to true -options>Applications>set pdf view application

The trouble: when I set the viewing application for pdf to Foxit, firefox automatically downloads the pdf to open it in the separate application. Up until firefox 19, the Foxit reader application would open in the browser. Since Foxit does not have a firefox add-on, how do I disable the firefox 19 pdf viewer and use Foxit Reader to open pdfs as a new tab in the browser?

Firefox just made me update to 13.0.1, and now I can't search on with google, yahoo, ixquick, or startpage. Whenever I do I get this:

Secure Connection Failed

An error occurred during a connection to startpage.com.

SSL received a record with an incorrect Message Authentication Code.

(Error code: ssl_error_bad_mac_read)

I've tried reinstalling it, installing older versions, and troubleshooting pages, but nothing works. I can go to websites that I have favorited or ones that I have links too, but I can't just use search bars. Does anyone else have this problem, and know how to fix it?

FireFox v13.0.1 installed on Win 7/64 system.

Adobe Flash and Shockwave installed yesterday.

Whenever I try to view a Youtube video, I select it and the screen with the arrow appears. When I click on the start arrow, the screen goes black and a warning on the screen appears:

An error occurred. Please try again later.

On the same machine, YouTube videos play fine on IE v9 and Google Chrome v19.0.1084.56 m.

Suggestions, or is this goodbye to FireFox?

Thanks

Previously, I had installed the Symbola font because certain symbols were not displaying properly in Firefox (notably on Twitter). Installing the font solved the problem for the most part (the four bit hex characters still didn't show up, but the six bit ones did).

After updating to 13.0.1 the other day, the six bit hex codes do not show the correct symbol anymore with Symbola still installed. I even deleted Symbola from my fonts, redownloaded it (a newer version, no less), installed it, and opened Firefox, and it did not solve the issue. Like the 50 million other things that Firefox broke with the update to 13. -_-

EDIT: This issue has since persisted with 14.0.1.
