This happened a bit ago and I found the one topic with the similar name but I can not comment or reply there as it essentially seems to have been locked for additional posting and remarks or I have not posted enough yet.
Regardless this has just happened to my Firefox v48.0.2 on my primary work machine and while it hasn't happened yet on my laptop which is running v66.0.3, I am concerned and not sure if things have been fixed yet on Firefox end or not and if I will end up experiencing this on that machine also as others seemed to have mentioned in the other topic.
my base question is how can I at least re-enable them in v48.0.2"
I have tried the xpinstall.signatures.required resting it to false but it still has not re-enabled them.
Any real suggestions or input as to what I can do is appreciated and also any input as to maybe follow whats happening on the Firefox side to see their progress on fixing this.
I can not really upgrade my OS on the main workhorse machine easily as there are many things that have to be converted and updated application wise and soem are well just no longer available properly to do the job that machine does for me atm.
TIA
