Hi OnTheRoad41, this error message indicates that the site is trying to use an obsolete encryption cipher which is vulnerable to the "Logjam" attack that was in the news earlier this year.
What does that mean?
Even though you trust the server, a "Logjam" attack compromises the security of your individual connection to the server, lowering the protection normally provided by SSL to a level that is easily cracked and read by others on the network. That is why Firefox protects you from making this connection.
What can you do now?
The very best solution for the protection of all users of that server is for United to change some settings on the server. If the information you can view on the server is sensitive, then this fix is overdue, so we encourage you to report the problem ASAP.
If you cannot wait, you can try disabling these old ciphers in your Firefox, which hopefully will force the server to try some more secure ciphers when connecting with you. Here's how:
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste dhe and pause while the list is filtered
(3) Double-click the security.ssl3.dhe_rsa_aes_128_sha preference to switch it from true to false (disable Firefox from using this cipher)
(4) Double-click the security.ssl3.dhe_rsa_aes_256_sha preference to switch it from true to false (disable Firefox from using this cipher)
Then try the site again; you might have to reload the page using Ctrl+Shift+r to bypass cached information.
Success?

Dark blue on Linux terminal difficult to read


Change Blue into Cyan ... it is just a lot more readable.

How?
Very easy once you know it:

Open a shell and stay in your home directory.
Do the following:
$> dircolors | sed -e "s/34/36/" > setColors.bash

This will create the file setColors.bash containing the current color settings for the terminal with the value of 34 changed into 36.

To try the setting, do the following:
$> .  ./setColors.bash

Your current terminal session will now show directories in cyan instead of blue. Use ls -l to see the difference. Notice also the dot followed by a space in front of ./setColors.bash.

To make the change for all your future sessions, you need to modify the profile script which is run when you create the terminal session. In case you're using bash, look for the .profile_bash file.

You can then either copy the content of the setColors.bash file into the profile file or call the execution of it. Make sure to execute the script in the current shell  and not in a subshell by using the mentionned dot space notation.

I needed to remove the screenshots ... thanks blogspot ... just doesn't work.

Example of how it looks before the change:

The output of dircolors: (notice the 34's)


Create the setColors.bash script:


The content of the setColors.bash file: (notice the changed values for 34 into 36)


The line appended in the .bash_profile file in the hone directory of the user:



Example of how it looks after the change:
