Firefox Browser Validation Error 54
I cannot access access Ancestry.ca due to a Firefox Browser Validation Error 54. Ancestry says this is a client side problem, it is not on their side. Sometimes I can access and sign in the website with no problems, then when I sign out, I cannot sign in due to a Firefox Browser Validation Error 54 again. This has been ongoing for about four months. How can I fix this Browser Validation Error 54 so I can access Ancestry.ca.

I have several versions of Firefox and had no problem.
I have no idea what that error means.

Is there a reason you are using an older version of Firefox?
There is security software like Avast, Kaspersky, BitDefender and ESET that
intercept secure connection certificates and send their own.

Verify that you meet the System Requirements (GTK+ and GLib) for the current Firefox release.
It your Ubuntu Linux distribution still supported with updates or has it reached EOL (end of live) ?
