EDIT: Apologies. Updated with a link to what gorhill REALLY said:
Manifest v2 uBO will not be automatically replaced by Manifest v3 uBOL[ight]. uBOL is too different from uBO for it to silently replace uBO – you will have to explicitly make a choice as to which extension should replace uBO according to your own prerogatives.
Ultimately whether uBOL is an acceptable alternative to uBO is up to you, it’s not a choice that will be made for you.
Will development of uBO continue? Yes, there are other browsers which are not deprecating Manifest v2, e.g. Firefox.
That’s by design. uBlock is blocking ad and spyware network requests. It’s common for sites to crash or error because of this. They’ll depend on a call to Google or Sentry or DataDog to succeed before continuing with their initialization. As a platform engineer for several web properties, I die a little inside every time I see this happen.
It works flawlessly on my personal devices. I’m assuming the errors are due to something with our intranet security.
Have you tried VPN?
