onloadwff.js consistently interrupts debugging in chrome devtools

[niusz]

Frequently when I am trying to debug pretty much anything in Chrome devtools using the sources window, this file: chrome-extension://hdokiejnpimakedhajhdlcegeplioahd/onloadwff.js opens up in the sources window and effectively prevents me from using devtools.

It is disruptive enough that I am considering uninstalling Lastpass. And even I checked blackbox content script it doesn't work. I am using mac10.13.6 chrome 71.0.3578.98

This is your lastpass extension, not chrome creating the error
