Slow down the browsing experience.

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).

The extension itself works fine, but they have started charging for it.
Initially, it was completely free on both iOS and desktop. After that, they started charging on iOS after three pop-ups were blocked, but said that desktop would remain free.
However, I've just received a message from the extension saying that they will also only allow three blocks per day on desktop.
Consent-O-Matic is completely free, works just as well (or even better) most of the time, and is open source.
The daily messages telling me to pay on iOS were annoying; I won't put up with them on desktop either. It was nice while it lasted, but I'm going to uninstall it.
If you're OK with paying, go for it — it's a fine extension. Otherwise, just install Consent-O-Matic.

Sadly, a case study as to why to not enable automatic updates. Clippy and Louis Rossmann would be sad. Created an account to review due to recent changes.

I will give the author credit where it is due, he seems to be updating the extension regularly. It's now on version 3.31 and as far as I can tell, the subscription wording was added back 3.29, and I've since downgraded to 3.28 and will leave it there until I find a replacement. I will also give the author credit for creating a popup to let me know as I hadn't realized it had stopped working. And I learned that downgrading an extension is a built in feature of Firefox.

The only other extension I know that charges is PushBullet, but their free option is quite more generous than '3 times a day.' I also rather look at it that something has changed for the developer as he now feels he needs funds and hope things turn out well for him. It's easier to think that, than something like he just got greedy. Or maybe it's better the other way around?

For what it claims, it seems to do what is says. Only had some issues with locally hosted sites, but the blacklist feature is useful enough for that.

Edit:
Updated to 2 stars due to friendly developer response. I cannot go farther than that because they change the extension after the fact. Would have no issue if it was like that from the start. It's unfortunate because I see where the developer is coming from (as a programmer myself) and I understand the thought process, but can't support the act. If you see this Francisco, I thank you for your offer, but I'll have to refuse on principle.

The extension causes YouTube Watch Later and other Notifications to load painfully slowly.

Potentially a fantastic addon, but in use it seems to really slow down FireFox on all platforms.

Get this issue resolved and your onto a winner, likely up there with some of the most popular.

Until then, it's on ice.

popups not detected
(clear the cookies 1st in your browser before test)
for example the cookies messages of the site
https://www.thomann.de/


same problem with the addon "Auto Cookie Optout"

EDIT: to answer the developper:
No www.thomann.de has still the same problem, so i don't know how you test your algorithm recognition.

This extension feels underbaked. I liked that you could select which type of cookies to accept so I switched from the I Don't Care About Cookies extension to Super Agent. Just in the past hour or two, I've run into two websites where Super Agent didn't detect their cookie prompts. Needs a single-click reporting feature for websites where the cookie prompt isn't caught by the extension.
