About Google Chrome's "This extension may soon no longer be supported"

Starting with Google Chrome 127, there will be a warning for uBlock Origin (uBO) in your chrome://extensions/ page:

This is the result of Manifest v2 support being deprecated in favor of Manifest v3.

uBO is a Manifest v2 extension, hence the warning in your Google Chrome browser. There is no Manifest v3 version of uBO, hence the browser will suggest alternative extensions as a replacement of uBO:

uBO Lite (uBOL) is pared-down version of uBO with a best effort at converting filter lists used by uBO into a Manifest v3-compliant approach, with a focus on reliability and efficiency as has been the case with uBO since first published in June 2014.

However the focus on reliability and efficiency in a Manifest v3 environment meant having to sacrifice many features beyond those not possible within a Manifest v3 framework.

See the official uBOL FAQ webpage for more details about how uBOL compares to uBO.

Manifest v2 uBO will not be automatically replaced by Manifest v3 uBOL; 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.
