When I use the Clippings keyboard shortcut (ALT+SHIFT+Y), instead of getting the Shotcut Key pop-up like usual, I am now getting the "Search for clipping by name" pop-up. I tried hitting TAB to switch modes, but nothing happens. I've read some posts with the same issue, but haven't been able to resolve by myself. Please help!
This started happening about two weeks ago.
Clippings 6.2
FF 72.0.1 (64-bit Win10)
Per 
this post I did open Developer Tools and got this in Console:
Source map error: Error: NetworkError when attempting to fetch resource.
Resource URL: moz-extension://a19aa089-5605-4e6e-ba61-7ce08197f79c/lib/purify.min.js
Source Map URL: purify.min.js.map
I have tried:
- Restarting FF
- Updating FF (latest version as of today)
- Turning add-on off and on
 
- Uninstalling and reinstalling add-on
- Toggling shortcut key mode on/off and changing the character
