When one browses to a website, and it fails to load with the little grey label that says "A plugin is required to play this content", how on earth does one identify WHICH plugin?

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.

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?

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'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

How to turn off Java version check

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 Suddenly the system started complaining java my java version is outdated messing up the kiosk display.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 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.

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?
