No instructions on how to use it. Not intuitive to use. I have not a clue if it is doing anything because of this. I will leave it on incase it is working. It would be better as an app to work all the time my device is on rather than just inside my browser.

issues with captchas

I love this extension, but it is breaking Linkedin right now. There is an issue open on github already, are there plans to fix this issue in the upcoming weeks?

This particular extension draws too much power from my laptop. Otherwise it is working incredibly well.

There is a little problem with it... this extension is used by a relatively small community. When a site makes a fingerprint of your browser, the part of the fingerprint is the used extensions... If you can't hide your extension, then the existance of it with some other parameters are enough to track you. IMHO

I would like to give this Add-On more then 2 1/2 stars (which is what I selected but it's showing 3 starts). In general, it does seem to work with some flaws. For me, my biggest issue, or what annoys me about all add-ons, is that they will always slow down your browser and CanvasBlocker is no exception to this. It does slow down my browser quite a bit, but I suppose that can vary from user to user depending on what you've selected as its settings. So don't be surprised if it does slow down your browser.

If you are using the Privacy Badger Add-On, expect the Add-On's to conflict with each other a lot, or from time to time. Depending on the type of internet user you are (or Netizen); if you are normally intimidated by what seems to be a complicated Add-On with lots of options to select, or you don't know what DOMRect, webGL, or APIs means, don't let that discourage, or prevent you from using it. Take your time to read how to use this extension (Add-On) and you should be good.

Works, but slows some sites to a crawl (i.e., eBay). Settings are hard to understand. Unclear how to whitelist a site.

Плохо, что нельзя установить на Firefox для Android. А в остальном отличное дополнение!

This add-on needs instructions on how to use. If present already they need to be easier to find.

Nice addon, but why it needs reading and changing privacy settings? This is new after the last update. Why you need that now?

I can't find a way to exclude Google Maps (unless I exclude all of Google, which I don't wanna). And this makes Google Maps totally hang always.
So, basically either this add-on or Google Maps.
Would be 5 stars if it had a better way of excluding URL patters.

Settings are overly complicated.

Help me: I changed a parameter i do not know which one and i think that because of that i can not solve the captchas anymore! :(
