"Hide and Show" feature is advertised, and I selected and installed the Add-on exactly for this use case. Now I can't find the feature. Can you please point me to it ?
See 2 "discussion" on this page related to the feature. My Conclusion: Falls short of this advertised use-case. Rating down for the time being until the discussion brings a solution to the restrictions.

I love it! Only thing is: it does not seem to work if a webshop is using Adyen as a payment method. At least with the 'shop' from dpd.nl dpd.de which uses Adyen.

Great privacy protection in a world where you have to comprise and use Google services and SOME from time to time

My experience in this addon is pretty good, but occasionally, The addon kinda reset, so my custom preferences in the addon returns to default state. But my website which i login-ed didn't sign-out, which is a good thing.

I love this extension, but I would like to use my own icons for the containers instead of using the default ones.

This is an excellent concept. I'm not so bothered about separating sites by category but containerising individual known bad organisations so that they cannot access anyone else's cookies is fantastic. However, I've only awarded 4-stars due to 1. low number and range of container colours available, 2. No ability to pre-assign sites by direct url entry - for some reason you have to open them first and then assign them then assign them from the drop down, 3. No ability to assign sites by domain - you have to open each site then assign them individually which is both laborious and prone to error.

I would rate it higher if there was more advanced features to customize. It's too bare bones as is.
