They should have forseen the certificate issues and never implemented the system as it is, i.e. disabling addons that have been installed with a valid cert. At most there should be a warning. Addons are losing their configuration because of this and we have yet to see how they fix old FF versions. All of this indicates a total lack of foresight.
However, I see the value in having studies enabled and being able to test features and fixes with certain hardware configurations. Almost every software does it, because it's very useful. Maybe Mozilla, being an advocate for privacy, should be more transparent about it though.
For me, it's the other way around.
