It most definitely is as well. In fact it's better because you don't have the slower page loading times anymore.
And everyone I know who used UBO and switched to UBOL has had no complaints about ads not being blocked.
Whereas people who don't actually use it love to continue to insist that it's this degraded experience that doesn't work as well. And usually when one of them comes up with an example of some ad not being blocked, it turns out because they hadn't configured UBOL to use complete blocking mode.
Everyone who you know is irrelevant. I've tested and see that ads pass through, and tracking passes through with uBo light on Chrome. I can see it in the browser trace, and I can see it in DNS logs.
Your test is irrelevant. There is always going to be some tiny percentage of ads that passed through with any ad blocker. So the fact that you have seen ads passed through with it doesn't actually mean anything.
The only thing that means anything is how well it operates with your average browsing on a daily basis. And it's such a popular extension because it does an amazing job at blocking ads. That's just a fact. The only people who seem to claim otherwise appear to be the ones with an ideological axe to grind. It's silly.
Your opinion is nothingness. I've tested on the same page that uBo on Firefox blocks more than Chrome, and especially it blocks hidden tracking. That's the reality. All else is irrelevant.
