It can not block every cookie which is a bit weird.
It does what it has to do that is perfect enough for me to a certain point.
It does slow down pages a bit not by much but neither i care for that.

All that matters is it works for what they wanted it to work and even tho it does not work on every page is a bit of a problem when you cant block certain pages to create those spyware cookies...

The sad part is is not getting new updates no more...

Makes page loadings hang with setting 'on leave' enabled.

Also no longer maintained as stated at github.

Works well. The only downside is that is requires "Container Tabs" which cannot be disabled if this extension is installed.

permertly delete exististing extension & API cookies

Configuration is a bit tricky. When it is configured correctly, it works perfectly.

This is an excellent add-on. It automatically deletes cookies that I don't mark for saving. Since using this software, I no longer get "personalized" ads and other BS indicating I am being tracked across sites. For those of you who claim it doesn't work, delete all your cookies, once, through the Firefox interface for managing data. From that time on, you'll see that your cookies for a site will stay active until you close the tab(s) for that site. After closing the tab(s), depending on how you set it up, Forget Me Not will delete the cookies for that site after a delay, or immediately. You will see that you cookie list consists only of those you allow.

классная штука

This is a test

happy

I was starting to feel intoxicated until the end of the week.

This is the one.

I think this is not nessecary on Desktop, the "Data protection-Cookies and Website data - Manage exceptions" should deal with that.

Essential on mobile, to delete all cookies apart from selected sites. I integrated it to my custom addon collection

https://addons.mozilla.org/de/firefox/collections/17446767/Fenix-Addons/

it works pretty great! The UI is usable although a little small, and Addons are able to modify cookies and site data on Firefox Mobile.

A mobile interface with bigger buttons would be great.

I will ask the developers to add the addon among others to the official list.
