From 02be05e311ec2dc59f2a86595ff99e3481ec3544 Mon Sep 17 00:00:00 2001 From: Raymond Hill Date: Mon, 17 Apr 2017 10:10:23 -0400 Subject: [PATCH] Destroyed What uBlock can and can not (currently) do (markdown) --- What-uBlock-can-and-can-not-(currently)-do.md | 42 ------------------- 1 file changed, 42 deletions(-) delete mode 100644 What-uBlock-can-and-can-not-(currently)-do.md diff --git a/What-uBlock-can-and-can-not-(currently)-do.md b/What-uBlock-can-and-can-not-(currently)-do.md deleted file mode 100644 index 00ebd6e..0000000 --- a/What-uBlock-can-and-can-not-(currently)-do.md +++ /dev/null @@ -1,42 +0,0 @@ -#### "uBlock is just a stripped-down version of HTTP Switchboard". - -No. uBlock started off by extracting the pattern-filtering engines (net and cosmetic filters) from [HTTP Switchboard](https://github.com/gorhill/httpswitchboard#http-switchboard-for-chromium) ("HTTPSB"). These engines needed more work to bring them to maturity. Most of that work won't be ported back to HTTPSB. See ["The road ahead"](https://github.com/gorhill/httpswitchboard/issues/378) for details. - -#### "The memory usage isn't actually ABP's fault, _EasyList_ is like 40,000+ lines of rules that all have to be parsed by ABP". - -uBlock also parse _EasyList_, _EasyPrivacy_, _Malware domains_ lists, -and _Peter Lowes's Ad server_ list out of the box and yet uses less than half the -memory of [Adblock Plus](https://adblockplus.org/) ("ABP"), which is itself much more efficient than -[AdBlock](https://getadblock.com/) (at least this is what I have measured on Chromium-based browsers). - -#### "uBlock has all the features ABP has!" - -uBlock is its own thing, it doesn't try to be Adblock Plus or any other. - -The `$document` filter option is not supported, see [issue #405](https://github.com/chrisaljoudi/uBlock/issues/405). At time of writing, I see 10 such filters in _EasyList_. - -**Read carefully:** Not supporting `$document` filter option has absolutely **nothing** to do with uBlock being more efficient than ABP. It's a principle thing: the purpose of the `$document` filter option is to disable a blocker on a specific site. I do not want uBlock to submit itself to 3rd-party filter lists for when it should completely disable it self. - -#### "ABP has all the features uBlock has!" -No. uBlock currently offers you more: - -- [Extends the filter syntax](https://github.com/gorhill/uBlock/wiki/Static-filter-syntax). -- [Dynamic filtering](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering), the ability to point-and-click to filter on/off `script` and `iframe` tags, on a 1st- or 3rd-party basis. I consider this to be a [key feature](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering---examples) of uBlock. -- Element picker is more modern. -- Let you select most common filter lists out of the box, without the need to import them first. -- Supports hosts files (hostnames are translated into the equivalent of `||www.example.com^`). -- Ability to whitelist single web page, or a whole section of a web site. -- Ability to not load cosmetic filters (saves lot of memory). -- A log of the net requests showing allowed/blocked net requests, and which filter, if any, matched each net request. - -#### "uBlock has a smaller memory footprint than Ghostery or Disconnect." - -No it doesn't. Last time I checked, uBlock has a larger memory footprint than both -[Ghostery](https://www.ghostery.com) and [Disconnect](/disconnectme/disconnect). That's for their own memory footprint. I didn't look into their contributions to the memory footprint added to each web page. - -Regarding CPU footprint, I don't know, I didn't measure yet (maybe I will), but my hunch at this point is that the CPU overhead is higher than that of uBlock. I did run [CPU benchmark a very long time ago](https://github.com/gorhill/httpswitchboard/wiki/Doesn't-HTTPSB-add-a-significant-overhead-to-network-traffic%3F), and this was the case -- but after such a long time, I have to assume things have changed and I would need to benchmark again -- a time-consuming task. - -Keep in mind that uBlock, like ABP, Adguard, and some others allows users to enter their own filters, something not possible with Ghostery or Disconnect. - -There are also other differences, or similarities: uBlock, _Disconnect_ -and ABP are licensed under [GPL](http://en.wikipedia.org/wiki/GNU_General_Public_License).
