Hi,

with the latest update of umatrix, it can not block requests/connections of other addons or firefox itself (behind the scene).
it does not even list the requests/connections in the log.

for example

before the update of umatrix:
while updating the filterlists of uBlock Origin i could see in the umatrix logger that the requests were blocked.
and only after i allowed them in umatrix, the filterlists could be updated.

after the update of umatrix:
uBlock Origin can update the filterlists without being blocked and there are even no logs of the connections in the umatrix logger.

is this a bug or one of the new restrictions of being a webextension?

the ability of umatrix to block such requests/connections was the most important feature why i used it.
so it becomes nearly useless for me.
