Ok so here is a test.
#### Steps
1. Ensure click-to-play (or whatever equivalent) is enabled before launching the benchmark
1. Have only the "new tab" opened
1. Quit Firefox
1. Launch Firefox
1. Paste `http://news.yahoo.com/` in address bar, wait for page to finish loading, stops video top right
1. Open new tab, paste `http://news.google.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.huffingtonpost.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.cnn.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.nytimes.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.foxnews.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.nbcnews.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.dailymail.co.uk/`, wait for page to finish loading
1. Open new tab, paste `http://www.washingtonpost.com/`, wait for page to finish loading
1. Open new tab, paste `http://www.theguardian.com/`, wait for page to finish loading
1. Open new tab, paste `https://news.ycombinator.com/`, wait for page to finish loading
1. Leave the browser idle for two minutes
1. Open new tab, paste `about:memory`, wait for page to finish loading
1. Firefox: Click _GC_ button in _"Free memory"_ section
1. Firefox: Click _Measure_ button in _"Show memory reports"_ section
1. Firefox: Write down _"Explicit Allocations"_ value (see notes below) / Chromium: Write down _Σ_ value
So I did the **exact** above steps for no blocker, ABP, uBlock.
#### Results
- **Firefox**
- No blocker: **613.55 MB** (reference memory usage)
- **Adblock Plus** 2.6.6: **625.05 MB** (reference _plus_ 11.5 MB)
- **µBlock** 0.8.2.0: **426.85 MB** (reference _minus_ 186.7 MB, ABP _minus_ 198.2 MB)
- **Chromium**
- No blocker: **1,169.35 MB** (reference memory usage)
- **Adblock Plus** 1.8.8: **1,509.05 MB** (reference _plus_ 339.7 MB)
- **µBlock** 0.8.2.0: **1,042.94 MB** (reference _minus_ 126.41 MB, ABP _minus_ 466.11 MB)
#### Notes
Tested on Firefox 34 64-bit and Chromium 39 64-bit on Linux Mint. No other extensions were present. The filter lists for ABP and uBlock:
- EasyList
- Peter Lowe's Ad server list
- EasyPrivacy
- Fanboy's Social Blocking List
- Malware domain lists
- ABP-specifics: _"Acceptable ads"_ disabled
- uBlock-specifics: uBlock's filters enabled (+80 filters), extra malware domains (+1,459 filters)
Click-to-play **enabled** or equivalent in both browsers.
I chose the _"Explicit Allocations"_ figure because as per Firefox, it is "the single best number to focus on" with regard to memory usage.
Without going into details, hardware is i5 quadcore + 8 GB
If other users feel like repeating the tests, it would be nice just to confirm I got everything right.
