How fix Error code on Firefox: SSL_ERROR_UNSUPPORTED_VERSION

Error SSL_ERROR_UNSUPPORTED_VERSION pops up because the website uses an outdated encryption methodology which firefox doesn’t really support now. To temporarily access the website do the following:

  1. Type in “about:config” into the firefox browser address bar
  2. You will reach the “Proceed with Caution” page click on “Accept Risk and Continue
  3. On the net page in the “search preference name” section type in “security.tls.version.min
  4. Click on the pencil icon right next to the search result and change the no in the box to “1
  5. Open a new tab and try re-opening the website again.

Once done browsing the website follow the above steps and revert the no in the box from “1” to “3”. This is a very common problem faced while accessing civilian portals in most govt websites since they haven’t modified the encryption technologies at their end.
