Google Chrome users with the uBlock Origin extension installed started noticing that the browser flagged the extension as "soon to be unsupported." Here is why this happens and what to do with it.
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.
None of the other Chromium based browsers have the engineering power to go their own way. They are dependent on what Google adds or removes in Chromium.
uBO is the best one though. And Firefox is one of the major mainstream browsers. Is easier to get people to change to something well known rather than an obscure browser like librewolf.
Switching to another Chromium-based browser is a half-measure. Other Chromium-based browsers are on borrowed time.
As time goes on, it will become more difficult for them to maintain v2 support. Nobody has the resources to properly maintain a browser fork with more than minor modifications. And you can bet Google will go out of their way to make this difficult for everybody else.
I mean, sure, use what you're comfortable with if you really can't use a non-Chromium-based browser for some reason. But it means you're likely going to have to jump ship again sooner or later. Why not just jump once, to something with better long-term prospects?
Then again, the folks behind Arc Browser have expressed interest in becoming engine-agnostic, so perhaps there will be a Chromium-free Arc version in the future. That would be very cool.
