µBlock, a lean and fast blocker

Went from the adquard FF extension to ublock origin. Did some testing with the same filters and sites load anywhere from 5 to 30% faster

Great extension!

 

"Security Now" podcast of Sept 1st (with Steve Gibson) about uBlock Origin is online.

@gorhill

Could you please implement "Disable WebRTC" as an option? That would be great.

 

There's new cloud storage support added: https://github.com/gorhill/uBlock/wiki/Cloud-storage

 

There is an option for it already. See the screenshot in post #1454 of @Minimalist post - "Prevent WebRTC from leaking local IP addresses"

 

Quick question: is there any advantage of running other extensions, like Disconnect, together with uBlock Origin?

 

@gorhill - slightly OT - will this feature be coming to uMatrix also?

 

Not really sure if adds any benefit. And i dislike having multiple add-ons for achieving the same purpose..

Here is quick test from Raymond a while ago..You can configure uBlock at various levels, to block the unwanted resources as needed.

FYI, I replaced ABP+NoScript with uBlock Origin (configured in Medium Blocking mode).

I did an quick run over PB for 5 days on top of my uBlockO and it covered all. Here is the post about it..

 

I see, I have to install uBlock Origin ...

 

I have a questions does enabling currently I only got the following 2 filters enabled:

- easylist
- easylist Dutch (where I'm from)

will enabling more filters like the privacy ones and disconnect list make pages on average load faster or slower?
Maybe faster because it blocks more stuff from loading, or slower because it's taking up time blocking ****?

 

Good question. Enabling too much filters will probably slow down overall speed as extension will have to process large list.
When I was playing with extension settings I got best page load times with blocked 3rd party scripts and frames.

 

I tried 3rd party scripts/frames and while very effective it's to much of a hassle for me, get annoyed having to allow stuff frequently.

I've checked some network request times and pages did load significantly quicker with 5 of the major filters compared to 2.

 

uBlockOrigin seems to compare activated lists and only take into account elements of those lists only once. For instance, lets say list A blocks abcdefgh. And let's say list B blocks ghijkl. The B list will only be taken into account for items ijkl, because gh are already being taken care of through implementation of list A.

For instance, I use, among other lists, Fanboy+Easylist-Merged Ultilmate List, and also EasyList. Only 50 filters out of 57108 filters are used in EasyList, because 88895 filters out of 88946 are already being taken care of through Fanboy+EasyList-Merged Ultimate list. If I deactivate the latter and apply changes, then suddenly 56965 out of 57108 are now used from the EasyList.

 

Yes, it removes duplicates and some lists are more or less duplicates of another. Adding different lists will still add overall number of records that has to be checked when loading web pages. Selecting all lists would probably slow down browsing, but I never tried it to see how it would affect speed.

 

uBlock's Advantages are
- It removes duplicate filters (even functionally equal, as uBlock Engine decomposes the raw filter lists to Atomic Filter lists)
- It processes the filters more efficiently, and has more higher resistance towards registering more number of filter lists. I remember one user tested it with > 990K filters.
So, it is uncommon you see slow down when registering to little more number of filter lists..
(And personally i have registered to quite a few of them - here is my count - 117,006 network filters ＋ 51,243 cosmetic filters, on top of Medium blocking mode)

in uBlock, there are 3 sets of filter types -
- Dynamic URL Filters (highly efficient)
- Dynamic Filters (highly efficient)
- Static Filters (aka ABP compatible filters) (not so efficient, when compared to above two types.)

When creating an custom blocking filter, it is advised to create a rule using either Dynamic URL Filtering or Dynamic Filters. As both are much more efficient than static filters.

 

The more stuff is blocked, the faster a page will load.

Do not shy away from selecting whatever static filter lists you need, I haven't ever run into performance issues because of "too many filter lists selected". The relation between number of static filters and time it takes to "scan" a URL for a match is not 1:1, i.e. doubling the number of filters will not double the time it takes to scan a URL. The way uBlock's static filtering engine is designed makes it quite less sensitive to performance hit as filter count increases. I once loaded the 800,000+ hostnames from hpHosts and uBlock was able to handle this just fine.

I may run some benchmarks with silly amount of filters at one point to be sure no myth (aka baseless assertions) see the day of light regarding how many filters are too many performance-wise in uBlock. At this point, the worry should not be performance, but more how much more likely web page breakage will occur with more filters.

 

One way to help page load a lot and reduce privacy exposure without the hassles of blocking 3rd-scripts/frames is to use dynamic blocking in allow-all/block-exceptionally mode -- i.e. blocking your way up proper page rendering instead of unblocking your way down proper page rendering.

Start by globally blocking ubiquitous domains that are useless to you first, as they show up in the dynamic filtering pane.

For example, blocking facebook.com, facebook.net, twitter.com, twimg.com, outbrain.com, and such others as they appear in the lists of connected domains will already impact page load speed. If ever you visit Facebook, Twitter, etc., you can then disable locally the blocking of their respective domains. Not only page load speed will improve, but also your privacy exposure will be reduced a good chunk, as Facebook or Twitter won't be able anymore to build a history of your browsing activity.

 

Absolutely.

 

Is there a version for 'PaleMoon' Atom/WinXP? thank you

 

how to whitelist 3rd party scripts/frames in certain websites ?

uBlockO works in Palemoon, not sure about what is Atom/WinXP

 

You have a download link?
add-ons at firefox to load button is 'greyed' out

 

Maybe check at the below link -
https://github.com/gorhill/uBlock/releases

You can find xpi for stable release at above place ..

 

Thanks for your response, awesome! And thanks for the tip with dynamic blocking too, will def look into it extension is gold
