I couldn't install extension from the Microsoft store because of the flag "Block unsafe downloads over insecure connections".Today my extensions were corrupted once again and i couldnt install them from microsoft store anymore
Well i did grab them from google webstore, and took netcraft & bitdefender trafficlight as plus
Some minor bug, gonna report it to microsoft
ps. aswell the ublock origin from microsoft store is 1.20.0 still and the newest build on chrome webstore is already at 1.21.6
After resetting this flag to it's default the problem was gone.
