I think people beleve that due to uBO installation they are protected and perhaps you know that some of them even disable filtering modules in installed AV to have "better" protection. uBO have gained milions of users but maybe few thousands know how good prepare this addon to work.
uBO does not block malware downloads. That is what was tested. IP address\URL\web-content blocking was not tested.
The malicious file samples were obtained via honeypots and tested as a drive-by download from essentially private\non-public LAN IPs. It is explained in the test notes.
uBO will never succeed in drive-by download testing because it is merely a web-content blocker as Gorhill explains. It does not inspect any downloads whatsoever. It merely blocks IP\URL\scripts that are in a list.
Web content filtering is good for ad blocking, but for malicious site blocking it is only marginally effective. The only ones who think that malicious web content filtering is of utmost important are browser extension crazed security forum members.
It is so trivial to bypass blocking by what is in a list. Such blocking offers the equivalent of 1 in 100,000 protection.
Of course one can get much better protection out of uBO by configuring it for every single website, blocking javascript, third party scripts, etc, etc. However, only a minute number of people go through all the trouble because it is a major hassle.
