where do I find "about:config file to allow me to fix this error - ssl_error_weak_server_ephemeral_dh_key
I have read the feedback which suggests changing a setting in the about: config file but cannot find it.
I need to access a webpage and this error - ssl_error_weak_server_ephemeral_dh_key will not allow me to do so.

In order to change your Firefox Configuration please do the following steps :
- In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
- Click I'll be careful, I promise! to continue to the about:config page.
Note that the DHE cipher suites were disabled for a reason and re-enabling them will make you vulnerable for the Logjam attack. You can consider to use a separate profile with the two involved cipher suites enabled and use that profile for accessing the blocked sites.
You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.
