I’ve never seen this on Firefox ESR until today.

of forum page below:

Could be that Firefox ESR does not support TLS 1.3 or it is not turned on inside the browser.

Not an issue here.

I don’t know what TLS means so I uninstalled it.

Not a smart move IMHO.

I’ll probably install it again.

What is TLS?

@mchain,

Thank you.

I’m running FF ESR as well but can’t confirm your issue.

I just reinstalled it and I didn’t get any warning message. Also remembered all of my add on’s.

EDIT
Additional Info
Not nearly as many privacy add on’s as there used to be.
