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.
You might be surprised! This type of change is usually automated and centralized, so an administrator shouldn’t ever have to even touch any of those Chromebooks. Might be worth having a chat with your school administrators.
My own daughter is in online school now (it’s still a public school, it’s just not in a physical location) so she can use her own computer… but I have to do the user agent switcher thing because the school’s own website testing software isn’t Firefox-compatible. And the school is run by evil Pierson who basically has a monopoly on American public schools, so I’m guessing that’s true for all of those Chromebooks out there too.
Still, I might suggest it to them anyway just for the benefit of the other kids.
Yeah, they sign major contracts that have a lot of stipulations so they get the best deals since theyre govt funded. This backfires, ofc, by locking them into bad products.
Im not saying dont try, definitely do.
