Cannot read property 'messaging' of null
occures on page with facebook comments plugin unstalled
Chrome Version 54.0.2840.98 (64-bit) uMatrix 0.9.3.6
Similar to what I'm facing here - https://i.gyazo.com/b1d0f19bae034763505f21c19340558d.png
Mine happens randomly though and on any page.
@uBlock-user that is a different issue. The error message reported by OP typically occur on dynamically updated pages after stopping/restarting uBlock Origin without refreshing these page.
Your case is different, and it occurred to me once while testing uMatrix. If you have repro steps for this one, that would help, as I was not able to reproduce.

@gorhill Were you able to reproduce my bug or this bug ?
Secondly, for my bug, you need to have Chromium 57 or 58, install uBO and uMatrix, run them together for a while and if you click on any cell on the matrix, the cell will be unresponsive and when that happens if you right click and inspect that cell you will see what I posted in the picture.
Also, I have few additional Hosts File list for uMatrix if that makes any difference.
