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 Suddenly the system started complaining java my java version is outdated messing up the kiosk display.

- how did firefox figure out the java version is outdated if neither the frond end pc nor the back end server have access to the Internet - is there a way to turn off java security checking in one of the firefox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'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 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'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

I have updated my Firefox to the latest stable release 57 in a windows machine. I would like to know if TLS 1.2 is already enabled in my browser or do i need to make any changes in the default setup in order to make it active.

When i check "security.tls.version.min" it's shown "Value 1". Is that the right value to TLS 1.2 ?

Kindly advise.

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.

As of about firefox 63, it will no longer be possible to prevent firefox from checking for updates as the preference (option) to do so is being removed. In the past, it was simply a matter of setting the option to never check for updates. This is important in an organization as you want everyone to be at the same level. In such organizations, the latest firefox would be obtained once, checked out, then rolled out to the organization from it's support system team/person. Is there going to be a way to prevent the message "an update is available, please install?"
