- Rated 3 out of 5by emotwink, 15 days agoThis particular extension draws too much power from my laptop. Otherwise it is working incredibly well.

- Rated 4 out of 5by snadge, a month agonot perfect, but it helps, especially if it is used with other addons, it still doesn't randomize your fingerprint like BRAVE does, only BRAVE gets 3 yes's on EFF's 'cover your tracks' (Ads, Trackers, Fingerprints), or, this addon, with Ublock Origin, Privacy Badger, Local CDN and NoScript (is what I use on Librewolf) gets you all 3 yes's on EFF (1 in 900, so 'common as muck' fingerprint, and unable to track & trace through fingerprinting)

- Rated 5 out of 5by Júlio C. Oliveira, 4 months agoOn coveryourtracks.eff.org shows "Your browser has a unique fingerprint" with a red line under it, And on the section of hash it shows "randomized by first party domain", So I guess it is working some way.

- Rated 1 out of 5by Nibinaear, 5 months agoCaused massive slow down when using ebay and other websites. Firefox identified it as causing slow down, task manager showed as 30% cpu usage for FF.

posted 5 months agoThere is little I can do about the problem with eBay. Whitelisting the DOMRect-API helps:

https://github.com/kkapsner/CanvasBlocker/issues/563
That's why it's whitelisted in the convenience preset. - Rated 5 out of 5by Anonymous, 5 months ago

- Rated 3 out of 5by Firefox user 15183223, 6 months agoThere 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

posted 5 months agoI'm aware of that problem. But since it changes stuff it can always be detected.
But we try to spoof the "other parameters" so the tracking gets confused. - Rated 5 out of 5by Aminul, 7 months ago
