Yesterday, had an auto Edge update. Now when opening edge first time after a computer boot, Edge comes up with error of Safe Web extension failed to load properly. Go to extensions, turn off/on Safe Web couple of times, then it works OK. Sounds like an Edge issue, OK yesterday am & pm boot, Edge updated about 5:00 pm, problem started after that, same on boot this morning. more than coincidence happened after update. It is working but in manage extensions 'The extension failed to load properly. It might not be able to intercept network requests' and remains there even although green ticks are working.
Problem was caused by Edge. Late yesterday evening, MS EdgeWebview2.Runtime came thru'. This seems to be part of of Edge, This has solved the issue, no Edge notifications that Safe Web not loaded. This was the the same item that stopped the Print to PDF functioning. Nice to know MS test these things before release!
Firefox works OK - Extension 3.22.0.2 - Edge had few issues lately at turn of the year - could not print to PDF - numerous users with same issue At the moment,
Forgot to mention - Installed Version of extension 3.22.0.14
