Today Chrome prevented the Internet Download Manager MV2 extension from running. How's the extension doing on your system? A recent IDM update possibly mentioned "extending the use of the MV2 extension," but I'm uncertain.
I use Vivaldi, which uses the up-to-date Chromium engine, and IDM is working just fine here too. Once and a while toggling off the extension and toggling it back on works, on the rare occasion it stops working.
