Does Add-on to fix signing issue really need to be installed

[Mo_D]

I haven’t experienced any loss of extensions. Do I need to install this add-on to prevent inevitable future failures?

Would it be better to wait until such failure occurs to install the fix?

I hate to say it, but I’m hesitant to install anything from them now.

If you are on 52ESR, you don't really need the fix, since you can just set xpinstall.signatures.disabled to false and install or run any extensions you like.

Thanks. To be clear, the correct name of the pref is xpinstall.signatures.required. False is the value to disable the requirement for signatures.
