Adblock Plus (ABP) is an ad blocking extension for Mozilla Firefox (including Firefox for mobile), Google Chrome, Internet Explorer, Opera and Safari web browsers. Mozilla, within the week issued warnings that the memory consumption of Adblock Plus can be considerably high in some scenarios, even sucking up to gigabytes of memory from PCs using its Firefox browser.

Albeit, the amount of memory consumed may well increase no matter which browser you use, though Mozilla seems to be only one on the look out.

Instance given, PC running Firefox without AdBlock consumed 194MB of memory. Whilst 417MB was the case with AdBlock on. And in another test, memory usage jumped from 370MB to a whopping 1,960MB with the AdBlock plugin enabled.

Nicholas Nethercote, a developer for Mozilla, in a blog post appealed on ABP authors to work with them to reduce this overhead. In the meantime, it’s worth keeping these measurements in mind, particularly, if you hear people complaining about Firefox’s memory usage.
