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.

Used to be free and decided to swap to subscription based. Does not advertise that it is sub based.

Doesn't work unless you pay. Consent-o-matic does the same as this plugin but works on more sites, is free and open-source.

This USED to be a free plugin. Sadly, the developer has decided to chase money and remove all utility from the free version, with it only working "up to 3 times a day", otherwise asking for ~$10 per month. So, instead I will be uninstalling.

If you are reading this and haven't enabled automatic updates for plugins, then MAKE SURE TO DISABLE THEM!.

Louis Rossmann was right.

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.

Oh, thinking of making a funtune off "donations" then made very little, turns on the pay wall and blame others for not being nice.
How standard.
Leave.
Now.

Automatically opens intrusive pop up asking you to subscribe before working on more than three pages. Please don't make people pay for features that used to work for free.

Didn't do a ton for me to begin with, then popped up and asked for a subscription after saving me... 1.8 minutes of my time (apparently it kept track).

EDIT: Removed because it kept giving repeated popups. You aren't saving me time with cookies if I'm spending that time again dealing with your own popups.

This is a scam. They want you to pay for the extension after a while you have used it. Don't bother to install it. I will UNINSTALL it immediately!

Very good extension. Fills out every cookie dialog after a few seconds.

Unfortunately, slows Youtube in particular to a crawl, which makes it hard to recommend atm. I do hope this gets sorted out eventually because the concept is great.

bugs that have previously caused issues for YouTube on Firefox have been fixed. The new subscription model is quite restrictive but hope to see adjustments to it made soon. otherwise it seems to be able to automatically manage cookie consent.

Does not recognize any popups in the Finnish language

A helpful add-on that's continually being worked on. I see positive development, which is why I have no problem making a small financial contribution for my increased convenience and the time saved for other things.
Anyone who is upset about this small contribution should offer an at least comparable add-on for free – or keep quiet.

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

ok, but still many sites where cookie popups are displayed, at least you can see in the dashboard that it does work on some sites and saves you some time and nerves
edit: after they unsolicitedly pay walled spammed me and opened ad popups I bought the lifetime license, didn't even bother to answer my E-Mail why they have no way to backup the whitelist db which should be an integral part to the app. Not even a manual backup, not even working when copy pasting yourself between Browsers. No Support Reply.
Get a free one, like EU Consetomatic, which does the same for absolutely free and not just 30 clicks per month or ad spam.

One great app for auto refill all cookies questions.
