I see, but lite is much less effective. google has worked hard to make it lose its capabilities. it may still be effective at blocking youtube ads (though as it cannot use frequently updatable blocklists it probably has a higher delay for fixes when something breaks), but it cannot have specific rules for less popular sites, because of chrome’s low limit on allowed filtering rules, and even though it can hide ads, that’s not the sole function of ublock origin. ubo is a complex content blocker, with versatile tools to defuse site tracking on lots of websites. lite cannot do that anymore effectively, because both its capabilities have been reduced (e.g. it cannot edit network traffic anymore I think), and the number of filtering rules that it can load.

and even before lite, ubo could not be as effective on chrome as on firefox, because of slight differences in the extension api, with not so slight practical differences.
