because you do not have ticked "Permanently store exception" - I can see it is greyed out.

try to navigate to FF home folder
%APPDATA%\Mozilla\Firefox\Profiles
and find and rename (I prefer rename instead od felete because then you can revert changes) cert_override.txt and cert8.db (I would rename them to cert_override_old.txt and cert8_old.db). Then restart Firefox and check if the exception is clickable now

if this is not working you can try this guide from here

1 - Edit -> Preferences
2 - Advanced tab/button
3 - Encryption tab
4 - View Certificates
5 - Servers tab
6 - [find cert]
7 - Delete button
8 - OK to confirm delete
9 - OK to close Certificate Manager
10 - Close to close Preferences
11 - Add Exception button
12 - Confirm Security Exception button grayed out?
If not, you are done (jump to step 22); if not, continue to step 13.
13 - Cancel Add Security Exception
14 - Edit -> Preferences again
15 - Privacy tab/button
16 - clear your recent history link
17 - Time range to clear (I suggest Everything)
18 - Unselect all; Select Cache [only]
19 - Clear Now button
20 - Close to close Preferences
21 - Add Exception
22 - Unselect Permanently store this Exception
23 - Confirm Security Exception

it means your browser does not trust the certificate which is on the webpage you are browsing. whyt it is not trusted is because it was issued by not trusted certification authority (issued by yourself, for example) or because the content of the certificate does not meet the domain - e.g. domain name on certificat is domain.com and certificate is used on domain.org

I can see on your printscreens you are browsing your LAN so maybe som NAS or something like that and in this cas it is OK because you can trust your own certificate. if you see this when browsing public web like email, internetbanking, paypal etc then you should not login for example because it could be a phishing or so.

helpfinder,

I keep on getting the same message even after I click 'Confirm Security Exception'. I don't get the same message with my other identical device.
