Unable to start CID

For several days now, IceDragon would always crash on start-up. I used task manager to kill the process and made a second attempt. Until today this has always worked but this morning it will not start unless in safe mode. I removed many tabs to see if that would help but still nothing.

I’m guessing it may be something to do with an add-on. The most recent addition was Privacy Badger.

Any suggestions to get it running again please?
