10-20-23: getting slower to load or won't load or won't show gui to delete ads. can't capture some site's ads. no way to delete all the little social widgets at the same time. just getting TOO damn slow
3-17-23: Still the best addon on the net. But always room for improvement. Slow to respond often. Doesn't work on little social media widgets because you spend more time blocking each one than it's worth: fb,and others. No way to easily report pages where it does not work. Slow to mark offending jpgs and slow to load and block them. Still a very good addon, indispensable.
12-17-22: So far I see no way to block these little social media widgits which you have to delete one by one and this takes forever. Many sites incorporate their garbage into the main page and it's difficult if not impossible to get rid of it. In short it works like 95% of the time and for 5% you have to put up with website garbage. No easy way within the program to report sites and bugs.
7-20-22: no easy way to report pages that block it's use. Some pages it will not work. Often slow to bring up the block window.
9-16-21: Still great. On some sites when you try to use the eyedropper, the popup for the script to delete the ad does not appear or appears and then immediately disappears or does not appear at all. Making it difficult to select the script that needs to be blocked. Still a great addon though.

If you don't have ublock origin, you should get it. Best add on on the market. Extremely useful in eliminating the garbage idiot admined websites throw your way. Has a learning curve but not bad. Kudos to the developer for this program, wish they'd design a web browser too. Great.

Not working for twitch ads

It would get 5 stars, but it can't block Twitch ads.

Please Make for facebook add

Seemd good but can't block FB ad's even after i subscribed to tons of lists including fb-related

Very good add-on, but unfortunately lately it does not do one of its most important tasks. And that is to remove mid video ads in facebook videos.

Dopo oltre un anno di utilizzo con i filtri di default, il funzionamento merita 5 stelle con lode !

Purtroppo uBlock Origin funziona cosi bene da impedire la normale, quotidiana fruizione - da parte di un utente medio - di decine di pagine web da utilizzarsi per il lavoro, impedisce il normale funzionamento di pagine pubbliche, come ad es. i quotidiani, oltre al funzionamento di centinaia di pagine web lecite frequentate abitualmente.
Purtroppo sicurezza e soddisfasfazione sono due obiettivi non convergenti. Bisogna scegliere quale dei due è prioritario.
---
D'altra parte, non si può disabilitare permanentemente un sito tramite per ogni pagina che si visita, quindi ricordarsi di andare ogni volta nelle impostazioni di uBlock Origin, cancellare la regola e tornare a navigare.
---
uBlock Origin costringe ad una scelta radicale tra il poter visitare pagine necessarie alla propria attività, tra l'avere le informazioni che si cercano, e bloccare quasi tutto rinunciando ad attività necessarie e ad informazioni necessarie o di approfondimento generale.
---
Anche se il problema verrebbe solamente spostato, potrebbe essere utile aggiungere una scelta meno drastica che consenta tramite pulsante, di sospendere solo temporaneamente il funzionamento di uBlock Origin su specifiche pagine, riattivandone il funzionamento completo al riavvio del browser.

It works on my device and blocks almost every ads.
However, this add-ons works better on Chrome & Chromium, including Microsoft Edge Chromium. On Firefox, my webpages load so slowly.
The End.
