I can't even get it to download from the FireFox for Andriod Add-on page. For 4 years I've tried to get this add-on & others downloaded, but, nothing, no error msgs - nothing happens. . . Likely a FireFox & maybe even and/or issue with Samsung.. But, have people really looked at the dysfunctional maze to try & contact Firefox or posts requesting info on the forum that go unanswered... O well, someone finally needs to get a 1 star after 4 yrs.... Sorry

Loved how this blocked a lot of things, but at the same time, disliked how it blocked a lot things...Some pages won't open and it's frustrating. It may be that I have other similar extensions, but not worth the aggravation of disabling each one to see which one is causing the conflict, just to reinstall them again. Had to get rid of this. I'm by no means "techy", so I can't figure out what's wrong. Any developer response, I most likely will not understand...Also, dislike the privacy policy, which isn't so private..."Store unlimited amount of client-side data", really?

manca una chiara gestione: impostare una eccezione in tale ad-blocker è facile come la lettura del geroglifici. attuabile solo per i pochi... impostare youmath.it come eccezione, pur mantenendolo privo da fastidiose pubblicità è un mistero, anche per voi?

Causes the 20 "/usr/lib/firefox -contentproc" processes to baloon up to 26.4 GB (WITH A "G") each of *virtual* memory! If I disable it and restart they go back to ~2GB. If I re-enable it (don't have to restart) it jumps to ~32GB Each. All 20 processes.
(Linux Mint 20.2).

It was the best content blocker around until one week ago or so, when I updated my system and it started to make Firefox crash on the Facebook website. It crashes every few minutes, when one tries to change the audience of a post, check who reacted on a comment and on a few more occasions. Firefox 94.0.2 on Debian 11 here.

Logger button is missing in Firefox Nightly (Android)!

Problem in writing on several comment box on Facebook. Once disable the add-on, no more problems!

I don't know what is happening but Ublock Origin has suddenly stopped blocking ALL adverts - cannot add new ones, can't edit - can't do anything - sick of huge Google ads spread over every damn page.

Doesn't work on modern Android phones with Firefox for Android

Let's pretend that people can read English! What do I mean? I mean stop putting pictures in place of words because it pictures are worth a thousand words and I don't know what your icon means without a tutorial! I'm not going to keep clicking your icons and trying to figure out what they mean! Can't even figure out how to get rid of white list.

How does this work? No instructions. No nothing, just a bunch of useless information "about this extension".

Firefox settings says "disabled by private viewing. Don't know how to correct this. Please help.
TIA

Ublock Origin causes DNS leak with VPN browser extensions, revealing my ISP. In order to use a VPN extension securely, I have to disable Ublock Origin. With 'DuckDuckgo Privacy Essentials' (https://addons.mozilla.org/en-US/firefox/addon/duckduckgo-for-firefox/), along with more restrictive browser settings (block 3rd part trackers, etc.), I'm adequately covered for tracking. All I need after that is an effective ad blocker and I found a great one called 'AdBlock for Firefox' (https://addons.mozilla.org/en-US/firefox/addon/adblock-for-firefox/) - which not only allows me to run a VPN browser extension securely along side of it, but it even blocks YouTube ads. Ublock Origin has not only become a problem, it no longer serves any useful purpose for me. Ublock Origin add-on removed.
