Damages Linkedin, as other comments here and on github have noted. Enable 'Advanced' settings and add Linkedin.com to the whitelist and all is well again. Do NOT alter any other settings unless you want your browser vulnerable to the noted exploit mentioned in the FAQ.

Overall works well BUT, when protecting Navigator (choosing a different OS or browser, any of the 2) it is caught by https://iphey.com/

not 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)

Dear developer! Add-on has an issue. Faking=>Random number generator=> 'persistent' and 'constant' options don't work both! Please fix that or maybe I have to apply some browser settings?
Also preset parameters option doesn't appear.
I use Android versions of Firefox nightly or Fennec.


!!!UPD: Pls upload ver 1.10 here. Thanks in advance

As far as i know it worked fine for me so far, but i started using Google Sheets and it kill the performance. Very laggy and slow sheets.
When i disabled this extension it started to scroll smooth as a kitty.

Update: disabling the extension on the site fixed the issue.

I've been using this extension for quite a long while and it was working fine, but recently it has created trouble with ebay.co.uk on my laptop. I cannot navigate on eBay. I got the following error message: CanvasBlocker is slowing down Firefox. To speed up your browser stop that extension.

A good add-on with tons of settings, and information regarding them. Not a fan of the UI, though. The add-on window, only shows 5 options, and one search bar. I would like to see this expanded with more options relating to what's being blocked/altered (or is not), whitelisting, and so on. The main add-on Settings page also looks ugly, but at least it's functional.

Overall, I would suggest this add-on to others. I found it does a better job than competition, which considering how much there is, is pretty impressive.

Whitelisting works, and even has 2 different kinds of whitelisting. The global one, as well as the one by API breakdown. Both need to be updated in terms of UI response and have a better and faster way of adding a website. No easy way to set a safe setting that *just works*, something always breaks and there's no easy "whitelist this specific breakage" button available.

An sich funktioniert das AddOn sauber.
Ein Stern abzug gibt es für das etwas fummlige Menü und es bremmst den Browser merkbar aus.

Selbst beim Browser-Start braucht es ein paar Sekunden, bis es 100% läuft.

Great extension!
I would like to submit a suggestion, would it be possible to allow shortcut key to duplicate a tab in another profile?

I have a conflict between Privacy Badger and CanvasBlocker when starting FF or restarting with my restart_firefox.uc.js script, it stops at loading ex: google.com (home page), I press F5 then it loads.

Disabling Privacy Badger on google solves it... anyone else have this problem?
