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.

Started messing up stuff on firefox today...

I can't view some (my most visited) websites entirely after last update. Is there a way to revert to previous version?

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.

End of an era... This worked really amazing for a long time but suddenly, today, it blocks most websites from working at all now. Just a big cat and mouse game. Stupid corporations love to spend $10 to try and save $1. Just leave folks alone already. We don't want your ads, end of story.

Became useless after 4th Aug 23 update

Doesn't work anymore on youtube as of 4th of August 2023. It makes the video unplayable, only solution is deactivating it. Looks like google has finally caught on.

Whatever recent update / change was made has broken many, many sites. Some sites don't load at all, leaving a blank page. Some sites load some content and fail to load the rest. AdBlocker used to be a great add-on, but someone did something to break nearly every site on the Internet when this tool is enabled. Someone at AdAvoid needs to review the most recent change and undo it.

No idea what you did in your newest update, but you screwed it completely, incorrect scaling in websites, can't even press enter on a google search unless I disable it.

Сегодня AbBlock Ultimate сломал все сайты, либо не открываются, либо половина javascripts не работает. Обновите плиз

This extension was working great.... until the content delivery services began shutting off access to anyone running it. Pages just won't load anymore. *sigh* It was good while it lasted

It blocks ads, but it's started blocking entire pages or even entire sites. I have to shut it off to access anything anymore.

Not blocking

I thought this was supposed to be free. After 30 days, if was suspended and I was told I had to pay.

Currently completely blocks Google Tag Manager which effectively breaks a lot of websites that utilize it NOT FOR ADS but for functional logic like integrating a GDPR Consent Manager. When GTM gets blocked by the extension all the functional logic will fail to run causing all the web logic reliant on it to also fail breaking the page or parts of it.
The developer needs to immediately roll back the latest changes which block GTM and other scripts completely as this is the most lazy and irresponsible approach to handle ad removal!

It worked at first but then it started completely messing up how pages load and making certain sites I need to log into throw an error that only resolves by turning it off. I've had to whitelist so many sites just because they wouldn't load correctly.

so far so good. keep up the good work

edit: after the august 5 update, websites are not properly working. once the issue is fixed, will give 5-star rating then
