Firefox 社群討論區

ATT is my internet service provider. I use their website as my home screen. Yesterday, I started getting an error message when I tried to go on-line. I have contacted ATT, and they have determined that the problem is with Firefox, and not their website. I can go from the ATT screen to any other website, and it works fine. This is the message that I get:

Secure Connection Failed

An error occurred during a connection to www.att.com. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Below are two attached images, please take a look. From my understanding there are two different translation features built into firefox, you can identify them by looking at the attached screenshots. I very much dislike the translation features which has the "page icon". The other option which looks like an "alphabet icon" and has "EN" attached to it is very much welcome. I want to add this translation feature to the toolbar, however when i open up the "customize toolbar option" there is no translation feature available. How can i add it? I do remember that in previous firefox version, the translation feature was pinned to the very right of the bar.

I want to know what should I change to change between these two appearances. I tried to change everything with `browser.search` in about:config, but I don't see anything that changed it.
