8 months after the first, three star rating:
the add-on has been improved, is now much more stable and works well. Protects the privacy and saves loads of time. There are still sites where the settings need to be updated manually, but not too many and I'm not letting perfect be the enemy of good.
The "old" review: Good idea, but unstable implementation. Some pages hang (e.g. connect.garmin.com, with trust arc), with no way of cancelling the process, the only way is to disable the CoM. There seems to be an option to not run the CoM on a page (a check box "keep running on this site?") but it does not affect the process in any way.
Please fix it and/or provide some way of giving you feedback and learning about fixes.

Absolutely fantastic! Thank you for developing this extension!

A must for every avid Internet user. Works like a charm on most sites, and improves the experience on the internet extremely, especially when looking for news articles on sites I don't regularly visit. It would be interesting, if there are further lists that could be included, or whether new lists are included in the Standard .json.

O add-on que precisaba!! Marca todas as opcións dos avisos de cookies da GDPR seguindo unhas sinxelas liñas configurábeis. Tamén podes marcar que non funcione en certas páxinas. Aforrando tempo sen parar!! Grazas!! :)

Excellent module from a liable source, unfortunately, I had to uninstall it since it was blocking the access to my online bank. Otherwise, it works perfectly on a lot of websites.

very funny and scarry to see in the PiP opting out frame, scrolling through 100's of data thieves.

It's a lovely extension. I am working a project and this has helped me a lot.

Even if it's not working on all sites, I still enjoy it. Hope it stays supported in the future. Great work and thank you for saved nerves and time. ✌

Works

Superb addon. Works as intended on most popular sites. Hopefully there range of supported websites will grow/we'll get some sort of template creation tool for sites that are currently not supported.

This add-on works perfectly on the majority of websites! I just wait 2 seconds when opening a site with cookie pop-ups and the add-on automatically fills my preferences and closes the pop-up. Very handy, definitely recommend!

Very good work ! I hope this addon will be available very soon on latest Android Mozilla version too ! This worked very good and i was very disappointed when i saw it wasn't on new version.

Virtually seamless and saves lots of time reading cryptic cookie consents.
