在「10 Ad Blocking Extensions Tested for Best Performance」這篇看到各個 Ad Blocker 軟體的比較。
其中最知名的 AdBlock Plus (ABP) 會最慢的原因也很簡單，因為他預設值會放行廣告，這導致了效能掉很多：
If you’re wondering why the popular AdBlock Plus got low scores in some Chrome tests, the answer is simple and it’s purely down to the acceptable ads check box. Disable “Allow some non-intrusive advertising” and AdBlock Plus will performance wise, sit in the middle of the pack.
在 ABP 把 acceptable ads 擋掉後速度就比較接近了。不過，如果你願意接受 acceptable ads，也不應該選擇 ABP，因為其他也有支援 acceptable ads 的軟體效能比較好：
Whatever your opinion on acceptable ads, using the option in ABP is not recommended and if you wish to support showing specific ads while browsing, use something else. AdBlock, Adguard, AdRemover and SuperBlock all have an acceptable ads option of some sort, but none suffer a performance drop like ABP.
最後的結論，不論是 Google Chrome 或是 Firefox，贏家都是 uBlock Origin：
The overall winner in Firefox is simply the quickest, and that was µBlock origin. µ AdBlock is a fair choice if you want an easy to use but fast blocker, the rest are almost identical so it’s down to personal preference and the options available as to which one you use.
The winner in Chrome is a closer call when you consider the results from all three tests. But as it got a couple of firsts and a second, we would say µBlock Origin is the definite winner, it truly is fast and efficient as the author claims. Both Ghostery and Adguard are still excellent choices and are viable alternatives to µBlock Origin providing good performance in all 3 categories.
網路廣告愈來愈誇張，阻擋的功能變成趨勢了，在桌機上支援的軟體愈來愈完善，而在行動裝置上，iOS 9 也開始支援了：「Content blocking in iOS 9 is going to screw up way more than just ads」。
