this shows that there is no encryption tab:

1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
2. Click I'll be careful, I promise!, to continue to the about:config page.
3. Use the page's Search bar for security.enable_ssl3 double click that if its bold, it should now unbold.
4. Use the page's Search bar for security.enable_tls double click that if its bold, this should also unblod.

NOTE: If its not bold, dont double click it.

i cant fine the line security.enable_ssl3 and its make no different when i double click security.enable_tls ( still remain bold )

You can now only set a minimum TLS version and a maximum TLS version (0 means SSL3).

See http://kb.mozillazine.org/kb.mozillazine.org/Security.tls.version.*

• security.tls.version.min
• security.tls.version.max
• 0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, etc.

there is no encryption tab in advanced panel

i can't connect to facebook

You need to open the certificates tab (Options > Advanced > Certificates), there you will find the settings.

You can also check the connection settings in "Options > Advanced > Network".

• Tools > Options > Advanced > Network : Connection > Settings
• https://support.mozilla.org/kb/Options+window+-+Advanced+panel

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Please help me i can't find ssl setting after update to firefox 23 please help me

سلام من بعد از آپدیت به فایرفاکس 23 نمیتونم تنظیمات اس اس ال رو پیدا کنم لطفا کمک کنید نمیتونم برم فیس بوک

go to "about :config" search "security.tls.version.max" and set it "0" اون آدرسی که تو خط اول گفتم رو تو فایرفاکست بزن توش چیزی که خط دوم گفتم رو سرچ کن و به 0 تغییرش بده.حل میشه

Is there any way that we can bring back the "Encryption" tab ? because some websites does not work if we remove "Use TLS 1.0" check mark , so we have to mark it again to be able to access them and doing this repetitively using "about:config" way is a little hard .
