- A hosts file with a whitelist of your favorite sites at the top followed by a blacklist of known ad and bad sites speeds up surfing.
- Works on any platform with a web browser.
- Nope. Video game consoles have a web browser, as do unrooted iOS and Android devices, but they don't . On the other hand, most of them don't have browser extensions either apart from Firefox for Android, so it's kind of a wash. --Tepples (talk) 20:17, 19 December 2015 (UTC)
- Easy data control
- Hosts file ads block ads more efficiently than browser extensions.
- Hosts file is processed in the IP stack, which starts before your browser and certainly before
- Hosts files protect applications other than your primary web browser.
- Adblock Plus uses 65 MB or more of RAM.
- More like 128 to 151 MB. Two pages on ghacks confirm it: Adblocker memory consumption | Improved in Firefox 41 but still 65 MB] --APK
- The anti-ad-blocking ClarityRay service, acquired by Yahoo!, defeats Adblock Plus but hot hosts files.
- Adblock Plus is bribed not to work by default.
- Articles show how ad networks pay for inclusion in an "acceptable ads" whitelist and Adblock Plus bought the original AdBlock.
- Adblock Plus adds complexity in user mode, increasing the number of context switches in and out of kernel mode, compared to hosts.
- Disagree. In theory, a browser extension can handle a request entirely in the browser, without switching out to the kernel's IP stack at all.
- Adblock Plus is slower than a hosts file.
- Answers to Which leads to faster browsing, an ad blocker or an edited hosts file? by jjlin, March Ho, and others prove it out. --apk
