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

This was written a few months ago but the content is still relevant.

Please do not open issues about the removal of support for uBlock Origin in your browser, or other Chromium-based browsers.

uBlock Origin is still fully supported in Firefox and other Gecko-based browsers.

uBlock Origin Lite might be a suitable replacement, only you can make this determination, see "Frequently asked questions (FAQ)" for more details about uBlock Origin Lite.

Important: Note that to make uBO Lite closer to the blocking efficiency of uBO, you need to set the default filtering mode to Optimal or Complete. Out of the box the default filtering mode is Basic.
