It works occasionally, but never consistently. Sometimes it does not accrue tokens, other times it does not spend tokens, just ignores them. Most likely its getting interrupted by uBlock Origin or Privacy Badger. Doesn't appear to be much development going on with it. I hope future improvements focus on compatibility with the major add-ons. As of now it's not worth the extra resources.

Всё нормально работает за 1 проход на клаудфлаерее дадут аж 30 прохдов,, на хкапче за 1 проход дадут 5, те кто 1 звезду ставят и ноют рукожопы

It is easy but up to this stage, what am I doing?

Worked exactly one time. Really not worth the effort.

It isn't compatible with Firefox for android.

a few of time it works,but most of time i failed me

I hope you like the phrase "Please stand by, while we are checking your browser..." because you're going to be seeing a lot of it if you try to use this garbage, deceptive, broken system.

Good

Does not work. 5 tokens available but unable to access site.

This works well for me, even with a (mostly) private setup on a VPN and custom config. However, I use Firefox 75 ESR, so I cannot speak to interactions between newer versions of the browser and the extension.
