Tampermonkey not running scripts in Firefox Dev Edition 77.0b3

[madmuffinz]

All of my scripts are no longer running on Firefox Developer Edition 77.0b3 (I usually keep dev ediotion up to date)
I am not sure if it's the addon or the browser itself. I am not sure which setting to look into, since I never changed my settings.
I normally use the stable version of Tampermonkey, and I tried installing Tampermonkey Beta, but I have the same results.

Any settings or flags I should look into?

I've noticed that these script work that applies to direct URLs such as images:

Both scripts are working fine here using 77.0 (64-bit).
