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.
I’ve been using uBOLite for about a year and I’m pretty happy with it. You don’t have to give the extension access to the content on the page and all the filtering on the browser engine, not over JavaScript.
I hadn’t heard of this.
The FAQ says it’s not a 1 for 1 replacement. There’s a lot of features which can’t be ported.
It’s probably better than nothing for most people, but not as good as uBO was.
Still, I wonder why it’s not mentioned more often.
