### Release notes
https://github.com/gorhill/uBO-Extra/releases
### Description
An (optional) companion extension to uBlock Origin[1]: to gain ability to foil early hostile anti-user mechanisms working around content blockers.
### Purpose
Instart Logic's technology used to disguise third-party network requests as first-party network requests, INCLUDING the writing/reading of third-party cookies. I consider this to be extremely hostile to users, even those NOT using a content blocker, as it allows third-party servers to read/write cookies even if a user chose to block 3rd-party cookies.
The company behind the technology understand how hostile its technology is to users, and thus tries to hide what is being done by making it difficult to investigate by detecting whether the browser's developer console is opened, and when it detects it is opened, it ceases completely to make use of the obfuscation mechanism. The developer console-detecting code works only for Chromium-based browsers however, and therefore the obfuscation technology is not used when using Firefox (a different web page is served for Firefox).

***
The extension has no interactive UI, just an icon in the toolbar to remind it's enabled.
Your browser should allow you to hide the icon if it annoys you. Use uBlock Origin's logger if you want to see and possibly filter WebSocket connections made visible by uBO-Extra.

Works perfectly and updated frequently. I like all the custom options available so you can choose exactly what is blocked. I haven't had a problem with most news websites which are usually good at detecting ad blockers.
Use junto Ublock Origin + o Complemento uBlock Origin Extra os 2 são imbatives
機能は詳しくわからないのだけど、他の方がレビューしているように特定の条件で機能する uBlock Origin の追加の拡張機能のようですので、入れています。 お守り代わり。
Simplesmente PERFEITO. Valeu equipe de desenvolvimento dessa extensão. Meu muito obrigado!
Beutiful
Not much of an IT guy but.....This extension was suggested to me and WOW, This thing works!.....With the Original UBlock Origin of course
Дуже гарна аплікація.
Крутое расширение +300 % автору.
otima tambem
ótimo
The only good thing about this extension is you'll now know what websites don't want you as their customer. Too many websites capable of detecting this and uBlock Origin.
I guess it works? Maybe add it's functionality to the UBo extension so this doesn't need to be downloaded seperately
Um, is Extra needed with new Edge. I opened the websites on the list of websites that are helped by Extra with Extra off. And websites opened okay. Anyone know whether Extra is needed with new Edge. Thanks
Muy bueno ...Pero espero lo mejoren pues no me gustan los anuncios son muy molestos...
Since the update not a single page loads on chrome on any devices that have this extension installed. it has to be turned off for -every single webpage- for them to work.
Please add a way to block ads on kissanime.ru <3
Works great with blocking ads on gmail that gets pass the normal ad-block.
For those who are complaining that this Extra app is not blocking all anti-adblocker messages... The Extra app tries to block those messages, but some sites use really clever ways to detect adblockers, which are nearly impossible to block. You would see those anti-adblocker messages even more if you weren't running the Extra app, so let's be thankful for the efforts of the author, after all it's a free. ;)
The icon of uBlock Origin (the original, not the extra) has disappeared. I choose to hide the icon of Extra in Chrome menu and it worked well. The origin was showing and the extra was hidden. After a couple of hours, the extra was showing and the origin had disappeared (not hidden). I go to "Manage extensions" and the uB-origin was not simply "disabled". It had a "Reload" button beside. As this had never happened to me before, I'm unnistalling this "extra" thing.
funciona bien para bloquear publicidad
An absolute must-have plugin for any browser with all the junk on the internet these days.
Leo opiniones contrarias, para los sitios a los que yo entro, ver series sobre todo me funciona de diez, es una gran ayuda
Não tem opções como o origin, bloqueia muitos que não precisa; Portanto não mereçe o nome e tão pouco o extra precisa melhorar.
funciona bien
I use both uBlock origin and it's companion (uBlock Origin Extra), alongside adbock plus and script safe, and the uBlock origin extra does not block adblocking detectors. I have been to several sites that show a blocking window across the web page that shows a huge red hexagon with the words 'Adblock' and a diagonal line across it with "I know ads are annoying but unless we charge you to view this site, ads are the only revenue that keeps this site running, so, to continue viewing this site please disable your ad blocker", and there's a link for instructions on how to disable adblock plus and many other ad blockers, which does go to show that uBlock origins extra does not work at bypassing adblock detectors,
Lovely, A good assistant of Ublock Origin. They are also look like mortal combat team.
no acibaraba en las paginas regulares
it doesnt do anything
The most recent version, it seems, completely blocks all IMAGES on MSN.com... and all the images from any article that is clicked on. And so on and so forth. And turning it off for that site brings all the ads back.
Endlich wird einem auf wetteronline.de keine 3rd Party Werbung mehr untergeschoben. Super!
On Reddit, if my cursor went over a link it would freeze/slow my cursor down.
Hasta el momento funciona increiblemente bien. Muy recomendado
funciona bien
Still can't evade the mechanism that the Dallas Morning News uses to stop blocker users.
Funciona Bien Piola
Mandatory, particularly on gamepedia.
Absolutely indispensable, must have unless you like getting pestered every few minutes by endless nonsensical ads
uBlock Origin is the best browser blocker ever made... In my opinion the only one add-on in the Chrome Web Store that deserves the hassle. XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX........................................
Sangat direkomendasikan untuk pengguna uBlock Origin
It's a shame we have to use this to protect ourselves like this but in the battle against raging spamfests and infected flash ads, Raymond Hill should be heralded as an angel of freedom. Ublock Origin is the most seemless undemanding and efficient blocker I've ever used.(and I used host files in the late 80's) This addon for it works like an anti-missile missile, undoing the insidious adblocker blockers now found on most media sites.. Highly recommended
Отличное дополнения для Origin-ального расширения. Описанию соответствует. Конечно, если читать это описание :D
Funzt nirgends mehr, überall poppt werbung auf, toller blocker lmao!
Wehr sich nicht wehrt, lebt verkehrt. uBlock Origin Extra hilft wirksam gegen den Werbewahn. Die "Macher" reagieren schnell auf Veränderungen. Vielen Dank
excelente
Works like a charm, always wondered where some cookies came from. Pretty shady of some sites.
No bloquea los anti-addblock
Why isn't this integrated into main app?
With new Chrome update it's now useless at washington post.
