Update from 09.09.2025:

This addon seem to work pretty well, its one of the few not being scam and with real hard working devs behind it. The cookie protection differs from other addons which proofs you indeed use your own algorithm and don't just copy script from others. With outstanding results! Unfortunately, this addon is not only not longer free but the authors were really non-transparent about it:

In August 2025 "Super Agent" turned into a subscription model, which may be okay (you two guys keep working hard for providing support and updates).
BUT: You really should be honest with users - you know FF auto-updates Addons by default. You should make a disclaimer and exposing the last free version for all those users who just want to continue the free (unmaintained) addon. Even better: Providing a link to it with instruction how to stop auto-update in FF. Also, your addon history completely lacks of changelogs - uncool :(
Since you did not do this, this is the reason for [-2 stars].
One additional [-1 star] for not adding the purple commercial $ category in FF store to your addon. You better do that if you not want somebody to report it.

End of review (only some additional info):
I am not much of a programmer, but very experienced in testing ad blocker addons for FF for about 10 years now. For years now "Adguard", "Super Agent" (has AI) and "I [still] don't care about cookies" (static list - always up to date) are outstanding winners for cookie consent. But I think the most honorable engine is included in "Cookie-Banner-Blocker" (otsmr) as it contains multi-level detection but continuing development is abandond by now.
You should add the latter engine to yours and make some exceptions for pages like apps.datev.de (auto-logout even if added to your whitelist) and reCaptchas in general as Cookie-Banner-Blocker has a false positive there (it wrongly block all Captchas).

Never charge for something that used to be free.

excellent app, makes browsing the web a lot more pleasant. set it & forget it!

for me this extension is crucial. It works on most websites and saves a lot of time. I will support it since its services are a true difference maker for me

I don't visit a ton of websites often, so I forget I even have this until I do visit one, get the pop-up for cookies, and watch it disappear before I lazily click "accept cookies". It works, it's great.

I really like this extension. People are such weenies for always wanting something for free. I wonder what how they would feel if their time an energy was taken for granted so flippantly. The funny thing is, there have been several times that I thought about how much I liked this and wanted to go for the paid version, but I couldn't figure out how to get a lifetime subscription. So if the dev would like to drop a hint, I'd love to pick one up!

Used to be free and perfect, but now the developer just chases money with a crappy subscription model, making this plugin completely useless now. Sad to see.

The fact that there is a forever licence is a good option, but not for 30 bucks. Maybe if that was 2.99 I'd consider it.

Whew, I expected to find a backlash here.

It’s never easy for users to accept when a product moves to a paid business model after being free for a long time. We’ve seen this before with the Reddit API, Twitter API, or YouTube introducing Premium. In the end, developers are free to take that step, and I think it’s unfair to leave negative reviews just because of that change alone (especially from those who never gave a positive one when everything worked alright which - to be fair - includes me as well).

That said, I would have appreciated clearer communication beforehand, and maybe a discount for existing users as a small thank-you for their loyalty. Still, this is ultimately the developers’ decision to make.

Personally, I’m not a fan of subscriptions. Right now, I’m still weighing whether to go for the lifetime option or to look for an alternative. But I genuinely value that a one-time lifetime payment is an option at all, it’s something you rarely even get to choose these days.

The extension itself has always worked flawlessly for me, both on PC and on Firefox for Android. Sites that weren’t supported were usually added quickly after reporting, which shows real commitment from the team. And considering work that goes into developing and maintaining it, the pricing feels fair to me.

No matter if I will decide to pay or not, I hope the developers manage to rebuild trust with their userbase and appreciate their work. At the end of the day - when we're ignoring the fact it has been free before - this is a solid extension at a fair pricing model, despite the shift to a paid model having tarnished our feelings towards it.

you expect me to pay for stuff that can be done through ublock for free?
yah! that uninstall addon button comes real handy thanks.

I'm glad that the developer has listened to the users feedback and increased the limit. Now the extension is at least usable, and perhaps even useful. Only time will tell.

I don't understand people being upset just because a developer wants to earn some money off his work, what's wrong with that? That being said, I still despise subscriptions in general, and $30 is way too much for what it does in my humble opinion.

PS: remember that not everyone lives in a "first world" country, so the value proposition changes depending on where you're from.

The extension has a lame subscription model now that's unreasonable to pay for. Uninstalling, do better devs.

Edit: increased to two stars after reading dev's responses to past people, I still don't want to use this since I dislike subscription models and want to stand on principal, but I can understand the dev's reasoning somewhat.

Subscription business model slop. Boo. I would have purchased it if it was single-payment, developers have gone mad with subscriptions. Boo. Switching to Consent-O-Matic.

Simple and effective

Suddenly started charging a ridiculous rate for what was free. It is one thing to charge for your work - it is another thing entirely to suddenly switch to a paid model with zero transparency. The website for this extension doesn't mention anywhere that it is NOT FREE, nor does the extension page on the store. I will no longer be using this as a result

Update: the developer waited almost 2 weeks since my review, updated both this extension's store page and their website, and they've now posted a response claiming I was wrong. But neither place mentioned pricing (or "not free") when I originally posted. The pricing on the website is buried in the FAQs page, so technically it is there (as of now). Claiming that you informed customers of the business model change by putting in a pop-up that asks for money is not most people's idea of being transparent (compare that to a pop-up that warns me for several months in advance that you'll start charging)

Annoying pop up since newest update

Just spams people for donations
