Hi All,

I wanted to enable to SSl 3 and TLS 1.0 in my Firefox ESR 17.0.x web-browser, the changes that we can do in ESR 23 or higher versions are not working (like about:config solution)

I am using a file as security-prefs.js in following location c:\programe file(x86)\firefox\Mozilla Firefox\defaults\pref\ and I am not able to do so,

the contents of the security-prefs.js is as follows :- 

pref("general.useragent.security",       "U");

I believe these were the default settings in Firefox 22 and earlier: 

pref("security.enable_ssl3", true); 
pref("security.enable_tls", true);

Are you trying to lock them so they cannot be changed?

@jscher :- yes these are the settings for Firefox ESR 17, I am not trying to lock them but trying to change them as to accept only SSL 3.0, TLS 1.0 or SSL 3.0 and TLS 1.0 both.

I am doing so by adding the above mentioned file to prefs folder of firefox in programe files

I am able to get security changes for SSL 3.0 and TLS 1.0 individually but not able to enable them in combo i.e. SSL 3.0 + TLS 1.0.

I'm not sure what you mean. If both are set to true, doesn't that mean that both are enabled?

Note that in later Firefox versions security.ssl3.rsa_fips_des_ede3_sha = false to prevent issues with TLS

These are no longer supported in current Firefox releases since a long time 

pref("general.useragent.security",       "U");
pref("security.enable_ssl2",             false);

@jscher :- yes if both are set to true that does mean that it should enable both but somewhere in the script I am making some mistake which i not allowing me to do so, that is where i need the help.

@cor-el :- thanks for your comment, making security.ssl3.rsa_fips_des_ede3_sha as false helped me out
