I have noticed lately that when it comes to some webpages I actually have to disable this because it wont let me view anything on the site, then have to go into settings and turn it back on, other then that it blocks what i want it to.

hatte nicht den gewünschten Effekt erst der Perceptual Ad Blocker, den es leider nur mit Chrome gibt, zeigt Seiten wie Spiegel, Zeit, Bild wieder werbefrei und ohne Adblock Blockierung an! ich hoffe, den gibt es auch bald für firefox!

the drop down menu is totally confusing.

there is some weird symbol, a circle with a line in it at the top. I hover and submenu pops: CLICK to disable... CTRL+CLICK to....etc...

The thing changes color. I have NO IDEA what the the gray color means. I have NO IDEA what the BLUE COLOR means.

Below is says "requests blocked" followed by some numbers. THAT DOESN'T CHANGE whether I'm blocking or not.

Check boxes would be SO MUCH better.

cannot block Yandex banner on main page

uBlock Origin、Adblock Plus都不能防http://btkitty.kim/广告和弹窗。你在btkitty.kim上搜索番号、电影广告一堆，弹窗跳个不停。请改进。

Getting more and more ads these days

I've used this for a few weeks now. Seems good, but it needs to be more pedagogic in how to use it. It's like it's overly simplified and the understanding for what's what is lost. Since it's efficient and does take very little from cpu etc, I hope for more clear user pedagogy.

Was really pleased until Firefox 57 came to town.

Used to be fantastic but doesn't block Youtube ads reliably anymore.

Depuis la version 57 (beta), les pages refusent de se charger au milieu de la navigation (après quelques pages ouvertes).
J'ai du changer en ADP pour bloquer les pubs.
J'espère que cela va être corrigé dans 4 jours ? avant l'arrivée de firefox 57 !

Ubuntu Gnome 16.04.2 LTS 64-bit

Ebay pages do not load properly. Item descriptions are blank. Need to disable uBlock Origin whenever I go to Ebay. I don't know what other web pages are affected by this bug since the text just gets blanked out. So now you are on a web page and information is blanked out, but you don't know because it could just be a blank area in the web page.

One small issue, other then that it's all good.

El add-on es muy bueno, pero en las ultimas actualizaciones de Firefox causa problemas generando constantes reinicios del navegador inclusibe recien iniciado esté, se procedio a la revicion del navegador basandome en el foro de firefox, y al realizar la revision de cada uno de los add-on´s se llego a la conclucion de que esté era el que causaba el problema.

I felt obliged to edit part of my review from earlier on 10/28.

Re: uBlock Origin 1.14.16 and NoScript 5.1.2 / 5.1.3 now seem to work in Tor Browser.
It took several "removes" - uninstalls / reinstalls of NoScript before both addons worked in Tor Browser.
Finally had to remove most NS about:config or prefs.js entries left after uninstalling.

NoScript's remnant prefs "shouldn't" have bothered uBo, but apparently did.
That's the only thing different on the *LAST* uninstall / reinstall, when uBo and NoScript finally worked. No settings changes were made in either addon.

FWIW, NoScript and uBo did fine on my 2 machines, until the last few days. They both had updates in Oct '17, so one or both created an issue for the other.
Side: It's goofy not to be able to edit a recent review vs. forced to give another star rating.
