It's not clear to me from reading the article, if the headline is correct. From what I understand (non-native speaker) with the mentioned fix ABP uses less memory than last year without that fix. But does it make FF use less RAM in general, compared with FF with fix but without ABP? That's how I understand the headline, ABP makes you save RAM compared to using FF without ABP. But that's not how I understand the article.
Mmm, I see the ambiguity. It's meant to mean that "the combination of Firefox + AdBlock Plus will use less memory than it did previously", not "Firefox + AdBlock Plus will use less memory than Firefox alone".
The fix will also reduce the memory usage of Firefox when used without AdBlock Plus, but the difference will be small.
