Here is a sequence of steps that has been known to work.
- Uninstall BOB and clickies.
- Leave all the other API-associated addons on there as Chrome extensions.
- Install TamperMonkey (from the Chrome store). (Check to make sure it is in extensions and running.)
- Install clickies from userscripts.org, okay the TamperMonkey installation, and allow the next popup about website URLs something. (Check to make sure it was in TamperMonkey and enabled (by clicking TamperMonkey icon to the direct right of the address bar in Chrome then selecting Dashboard, you'll see the script listed w/ a number in a circle). Then sign into CC and check to make sure it showed up there.)
- Install BOB following the same steps.
You may want to uninstall Tampermonkey before all this, just to start clean. You might even remove everything, then put in those other add-ons prior to putting in TamperMonkey, Clickies and BOB.
