Well, actually idk whether it's from this extension fault or from Firefox or from Zorin OS Lite 15.3. The icon doesn't show up in the toolbar and no options too in the add-ons manager so I cant configure it. I dont have this problem in Windows 7 and Windows 10.

占用资源非常低，但是拦截功能也只有一般，百度搜索页面上的广告无法屏蔽。还是推荐使用的！

"Tray" popup window doesn´t fit (its design is a little bit broken). Please fix it. Beside that, it works perfectly.

This does what it says. Blocks the ads. That's perfect! However, some UI elements seem a bit "odd".

The power button is HUGE when the extension is clicked, and the extension page and stuff look so outdated.

Except that, it's fine!

Voilà 15 jours que je galérais comme un damné, passant d'une extension de blocage à une autre sans trouver satisfaction : c'est à dire sans que mon navigateur ralentisse TERRIBLEMENT chaque fois que je tentais d'écrire quoi que ce soit dans une fenêtre de recherche ou de sélectionner une option, rajouter un favori etc etc etc... dans quel que site que ce soit, notamment et surtout Youtube, avec presque 200 élements bloqués en moins de 5 minutes. Puis, TILT, j'ai E-N-F-I-N compris mon erreur stupide : IL SUFFISAIT DE RETIRER LE FILTRAGE ESTHETIQUE (qui peut se nommer ''filtre des scripts'' sur certaines extensions). Cette fichue option ralentit effroyablement le fonctionnement des sites, surtout Youtube. Pas la lecture des vidéos mais toute opération doublée par une autre en arrière plan ! C'est une plaie ! Fort heureusement elle se désactive facilement avec Ublock Origin depuis ses options directes, une chance ! En tous cas depuis sa désactivation tout roule pour moi. j'ai également retiré les mises-à-jour automatique, pour augmenter la vitesse de mon navigateur et ce que je conseille pour tous ceux qui ont un PC ou une connexion lent-e comme moi. RDV dans quelques temps si j'ai changé d'avis ou constaté d'autres désagréments je viendrai modifier mon avis et ma note

Very good extension, but unfortunately it cannot be synchronized between Chrome and Firefox, and Firefox cannot be synchronized with the Android version of Firefox, so it is often exported and imported between different browsers. Can users synchronize to their own cloud storage services?

Por ahora todo va bien. Bloquea los anuncios de youtube y de paginas de pelis piratas. No vuelve lento el navegador.

Would be great if we could set the default behavior to allow ads

It's a great add-on, no doubt about it. But I have two main issues with it:
a) I've recently noticed that YouTube videos played with this add-on on, won't show as "watched" (or partially watched) on my YouTube account.
b) As someone who doesn't mind adds (I mostly use the add-on for privacy and security, not as an add-blocker) as long as I support the site I'm using (e.g., it isn't part of Big Tech), it's pretty annoying to have to turn-off the add-on site by site, when it'd be much easier and practical if I could just turn it on on a few sites that I don't want to support.

There might be workarounds for these two issues that I'm just unaware of, though. It's a pretty thorough add-on that gets updated all the time.

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.
