same here the update caused all web pages i loaded to not load or function correctly however i am not going to rate it less stars simply because of a bug that im sure they will fix maybe if they do not fix it i might but for now i just chose see all versions under version history in the more information panel below and installed previous version then disabled auto update until there is another update.and ty developers for keeping my privacy safer i appreciate your hard work and time.

works fine

Previously this was the add blocker I loaded on all our computers and recommended to others. However YT's new algorithm will not play videos if this blocker is active. If I turn it off, everything plays. I really miss the old days and I certainly will not pay $14/month ransom to YT, it's not worth it.

doesn't work properly anymore, safe to assume get compromised. better safe than sorry, people!

latest update broke everything. disabled it for now.

has worked wonderfully for years but firefox updated aug 4 and now this extension is preventing many sites from loading. twitter won't load at all, other sites are missing half their images. switching it ublock origin, i guess

Worked great (for many years) until recent update. Many sites won't load. Even Google won't work right with it... dropdown menus and image previews quit working.

I uninstalled / reinstalled. Same problem. Bummer.

Had to uninstall permanently. Now I have ads cluttering up websites, and it sucks. No substitute that I know of. And it hasn't been updated to fix the problems from what I can see here.

Starting from today, this extension breaks every website I use: buttons disappear, links not clickable, webpage cannot load, etc. It worked fine before. Hope developers fix it soon.

I loved it! works supper well.
Just that google lastly is playing dirty and working bad when it detects this ad blocker.

I hope there is a way to the websites cannot detect the ad blocker.

After aug4 update, breaks most websites. I reckon the dev will fix it asap, but ive already changed extension. So long, Adblocker Ultimate!

Doesn't work with safe filter on. You can disable it in Settings ->Filters -> Security -> Click on switch / Не работает с включенным фильтром на безопасность. Отключается в настройках -> Фильтры -> Безопасность -> Переключаете в выключенное состояние

Great adblocker, also great for disabling distracting elements! Unfortunately when I woke up today, a lot of sites had issues, from YouTube, to Google, to DuckDuckGo, to WhatsApp and more. They all worked again after disabling this extension. Hopefully the error gets rolled back or fixed soon :) (Thank you devs for all the ads you've saved me from so far!)

After Firefox upgrade to 116.0.1 64 bit this extension corrupts almost every web site, amazon, walmart, amazon, facebook, yahoo, etc.

Up til now the extension has been great but due to reasons unknown (but likely the latest update), the extension now breaks a huge amount of different sites which renders the extension useless. Hopefully the developer will update and/or fix the extension soon.
edit: can confirm User 16992077's suggestion works. the issue seems to be with the security filter which can be turned off and the extension will then work as normal

I started disabling all of the add on and found out this thing stops all the site I use. I had this for long time now it stops working.

idk what happened but starting today, it seems youtube vids won't play while this addon is on. 🤷
never had that problem before.

As many others have pointed out, after the 4 August update it blocks a lot of websites entirely. Ones I've used daily with no issues. Another user recommended going into the extension settings, Filters tab, and turning off the Security filter (Ad filter continues to work fine), and this solved the problem for me.

Started messing up stuff on firefox today...

Hope this helps anyone who sees it. Many sites stopped working after the 4 Aug update, but I managed to get them working again after going into the extension settings, Filters tab, and turning off the Security filter. The Ad filter continues to work fine.

Youtube blocks playback now, if you have it activated on their site, uninstalling, I'll have to look for alternative

Like everyone else has said, the new update just completely ruined my online experience. Half of the websites I use won't load and I've just decided to remove this ad blocker entirely.
