FWIW, I am using uBO and NextDNS. No popup on that site.
@Kees1958 How is the AdGuard extension working out for you compared to uBO?
Some initial explanation.
Ghostery did a study on Adblocker efficiency after Google published Mv3. In those studies uBO processed the rules the fastest of them all (considering the amount of rules uBO has enabled in default mode). uBO's first launch in which the filters were read and re-ordered for effective access took way longer than any other adblock extension. Gorhill responded by compressing the blocklists and caching the optimized and re-ordered filter set (only re-creating it for updates).
Because I only use 5000+ rules and update my list a few times per year, uBlock initialized blazing fast (small list with few updates means it could use the cache). When I hit Shift Esc uBO only has used a second (probably less) while other extensions used up to 3 seconds CPU time to initialize. That said the new AGv4 uses only 1/3 of initializing CPU time and 2/3 of processing time (when opening a fixed sequence of websites). Still old uBO is a fraction faster than AGv4 when doing this comparative performance test. Because most is done in parallel after browser start when systems idles waiting for your response, the speed difference in practice is not noticeable anymore (now less than 0.2 seconds).
When people use default uBO (with way to much useless malware blocklists) and compare it with AGv4 optimized, my guess is that AGv4 default optimized will have a slight performance advantage over uBO default. In terms of blocking experience (as
@SeriousHoax has posted a few times), the AG (optimized) blocklists work better on AGv4 than uBO with default blocklists, the new and improved modifiers of the new rules engine will improve this (clean web experience) advantage even more.
As posted in the AGv4 thread (
link) the main advantage of AGv4 for me is that it is ManifestV3 ready. But you know me. I have a history of switching between uBO and AG, but at the moment I prefer AGv4 over uBO.
