When will my extensions become available on Firefox for Android?

[PurpleCookie]

@garrett explains how to achieve this via uBlock Origin:

Add-on support in new Firefox for Android

In the meantime, you can add the “I don’t care about cookies” blocklist to uBlock Origin in the Firefox. Go to uBlock Origin’s settings, tap on the dashboard, then visit the filter list tab, scroll to the bottom, and import a custom URL. The blocklist URL is https://www.i-dont-care-about-cookies.eu/abp/ It is quite a few more steps to set it up, but you’ll have a similar cookie reduced experience when done.
