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.
Comment from gorhill (the developer of uBO and uBOL):
I didn’t recommend to switch to uBO Lite, the article made that up. I merely pointed out Google Chrome currently presents uBO Lite as an alternative (along with 3 other content blockers), explained what uBO Lite is, and concluded that it may or may not be considered an acceptable alternative, it’s for each person to decide.

I haven’t used Chrome in years now. Firefox has always been my home.
Did I miss a piece? I don’t see anywhere in the original statement where firefox is actively recommended, just mentioned as an example.

What are the main differences, for someone considering going from Firefox to Librewolf?
Librewolf is to Firefox what Chromium is to Chrome, essentially. Removed many bloated Mozilla anti-features, has sensible (but not paranoid) privacy and security defaults and ships with uBlock origin pre-installed. You can archive all of that with Firefox, but Librewolf makes things easy for you.
