Extension memory usage: benchmarks over time
This page is a place to keep track of comparative memory usage over time. Screenshots are before/after reference benchmark. Great care employed to ensure memory was garbage collected before screenshots taken. To force memory garbage collection, browser left idle for more than 1 minute, then the dev console of each extension opened, Timeline tab, then clicked twice on the trashcan icon.

- Adblock Plus 1.8.8
- Adguard AdBlocker 1.0.3.8

After benchmark completed:
Observations during benchmark:
- ABP/AdBlock/Adguard are CPU intensive. Whereas uBlock consistently shows at most low-single digit CPU usage, other blockers are most often showing double-digit CPU usage, and sometimes in the high double-digit range.
Settings:
- uBlock 0.8.2.2: EasyList, EasyPrivacy, Peter Lowe's, Fanboy’s Social Blocking List, all malware lists (3). Launched with a valid selfie (i.e. less memory churning at launch).
- AdBlock 2.15: AdBlock custom filters, EasyList, EasyPrivacy, Peter Lowe's, Fanboy’s Social Blocking List, Malware protection.
- Adblock Plus 1.8.5: EasyList, EasyPrivacy, Peter Lowe's, Fanboy’s Social Blocking List, Malware Domains. Acceptable ads disabled.
- Adguard AdBlocker 1.0.3.8: English filters, Spyware filter, Peter Lowe's, Social media filter, Phishing and malware protection. Allow acceptable ads disabled.
