I noticed that just about every time i start my computer and open Nightly I get a download popup to download the OpenH264 codec by Cisco. I did and I noticed that there was an entry for it in the Plugins section of the Add-Ons Manager and it states 'Will be installed shortly'. What it had me download was a zip file that contained two files. One that gave a short explaination of the codec and a libgmpopenh264.so file. Now I have no clue what to do with the .so file to get it installed into Nightly.

Is anyone else having this issue and what can I do about it? I am running Xubuntu 14.04 64-bit.

I have been using firefox for years and have a system that work perfectly most of the time, and has all the usual suspects already installed. But when I see the message above, I just get frustrated because there is no link to follow, and so far as I can tell, no information at all to lead to a resolution of the issue.

Thanks for any pointers.

Pages with web fonts, like http://google.com/fonts, are not rendered correctly. All text that should be web fonts is shown with the default font. This is Firefox 20.0 on Ubuntu 13.04 with Gnome 3.8. - Starting in safe mode does not help. - neither does starting with a new blank profile. - There are no error messages in the Error Console. - Javascript is enabled. - not allowing hardware acceleration does not help. - the "Allow sites to use their own fonts" option is checked. - I am not behind a proxy.

What else is there to check?

I am using Firefox version 33.0 with an Ubuntu 14.04 LTS operating system. I get a 403- Forbidden: access is denied message when trying to access my Microsoft Outlook Web App (OWA) email. When I use another computer running Firefox version 33.1.1 with a Window 7 operating system, I can access my Microsoft Outlook Web App email perfectly. Does anyone have any suggestions on how to get my Firefox browser on the Ubuntu machine to be able to access my email on OWA?

Since sometime in October, 2013, I have noticed that more and more YouTube videos stop playing within a minute of starting. Most that stop do so in 15 or 16 seconds. The playing stops because the download stops. I watch this on a network activity monitor I always have running. Not all videos do this, but the problem is becoming more and more frequent. Some videos which played correctly for me in the recent past are now exhibiting this problem.

Other than installing the latest Firefox updates I have NOT changed the software on my machine. I run Linux by the way. I do not think this is a Linux problem because (1) it was all working before and (2) my son who runs both Mac OS X *and* Windows is also seeing the same problem. We both use Firefox as our browser on all our platforms.

I should also note that I am NOT seeing this problem with any of the other video websites I use, only when I go to YouTube. That leads me to believe that the problem is not in Firefox; if it were it should affect videos from all websites.

Additionally the problem occurs whether or not I log into YouTube.

I have not run Firefox in safe mode because all the extensions I use did not affect the download of Videos before, so I don't expect unchanged extensions to suddenly start causing problems.

So, anyone else see this problem? (There was another note which talked about the same problem but it was disabled.)

Also -- pardon my paranoia, but -- I need to ask: Since YouTube is owned by Google and Google has its own browser it wants you to use, Chrome, is it possible that Google is intentionally causing some YouTube videos to fail if it sees that they are being sent to Firefox?

(That is not so outlandish I think. Microsoft WAS at one point caught mangling web pages going to certain web browsers other than IE. And these days Google wants to dominate the Internet just as badly as Microsoft does, so why not pull dirty tricks too?)

If this keeps happening I am going to have to try Google's Chrome to see if it somehow manages to play YouTube videos correctly while Firefox does not. But I really do NOT want to install Chrome because I trust Google about as much as I trust Microsoft, which is to say Not At All.

Thanks in advance.

I have a small Linux based pc running Firefox in kiosk mode. The pc is not connected to the Internet and only has acess to a dedicated server under my control, serving a few webpages and a java applet. Suddenly the system started complaining java my java version is outdated messing up the kiosk display.

- how did firefox figure out the java version is outdated if neither the frond end pc nor the back end server have access to the Internet - is there a way to turn off java security checking in one of the firefox config files? The kiosk pc boots from the network, the firefox profile is automatically generated, so I need a way to change this in the config files, not through the GUI as I won't be there every time the kiosk boots.

I'm running Firefox 13.0.1, I know this is old but security isn't an issue as I'm only accessing my own server and updating the firefox version on the PXE image is a pain.

I'm using Firefox 41 for Linux 64 bit and I need to communicate over a proxy requiring authentication. I have to enter username and password after each start of Firefox. I found at this forum that setting of the following things in about:config would help but it does not:

network.negotiate-auth.allow-proxies : false network.proxy.share_proxy_settings  : false network.automatic-ntlm-auth.allow-proxies : false network.auth.use : false signon.autologin.proxy : true

So is there any way how to save the credentials to avoid repeated prompting for them in each new Firefox session?

Thank you for your help, Martin

Support for enablePrivilege has been removed in Firefox (Bug 546848), so it is no longer possible to get special elevated privileges by using this method.

If a web page (or local html page) is using this then they will have to use other ways get what they want like providing a Firefox extension.

Where is it possible to find an exension of this kind (if it exists)?

I'm trying to use a ssl proxy with accounts.google.com.

Usually, firefox warns me about invalid certs, however it let me add an exception if I wanted to connect to it anyway.

But, if i want to connect to accounts.google.com, it blocks me, and it doesn't let me add that exception.

Why it happens only with this subdomain?

One hour ago I was happily watching youtube videos under Linux using Firefox 20.0 and flash 11.2. I just updated firefox and it is now blocking my flash and prompting me to update. The problem is I can't update because 11.2 is the LAST flash plugin for firefox, there won't be any other version.

Is there a way to prevent firefox from disabling my plugin?

I am running a local apache server for website development. I have always accessed these local sites with http://

Suddenly today firefox is redirecting to https:// and I receive the "Secure Connection Failed" error.

I have completely removed the firefox profile by deleting the ~/.mozilla and ~/.cache/mozilla directories, but the problem persists.

I have set browser.urlbar.autoFill to false, but the problem persists.

I am not running any extensions or add ons.

No changes to the apache configuration have been made.

No system updates have been installed since it was working yesterday.

Even with apache stopped, the local sites still immediately redirect to https://

The sites are directed to localhost via the /etc/hosts file, for example: 127.0.0.1 examplelocalsite.dev

I have restarted the computer and the problem persists.

The problem is not occurring in Chrome.

The problem is not occurring with external http:// websites.

I am not running any type of security software other than a basic firewall configuration with ufw

The problem persists with ufw disabled.

I have purged the firefox installation with apt purge firefox and reinstalled fresh but the problem persists.
