I am not sure what happened today but all of a sudden All of my Firefox extensions were spontaneously and simultaneously disabled!
I have done a few things in about config trying to re-eneable them but nothing suggested by others has worked.
I even went and removed the extension and tried to reinstall it via the
https://extensions.jdownloader.org/firefox_48.xpi for the older web browser 48+ and got an error message
I have attached screen shots and not sure what to do atm any help is appreciated.
Again I am running Firefox 48.0.2 on Mac OS X 10.6.8
There are also some other posts from others that have had similar problems today with Firefox all of a sudden disabling all sorts of addons. Not sure if it has to do with signing and dates maybe associated with them or not but it might be the issue also.
Seaching for such as this shows a lot are having issues too"
