I wasted time on the phone with customer service – getting the normal CSR script about cleaning my cache, etc. However, when I tried to select certain options during the normal bill-pay process, my selections were not being seen and I kept getting kicked back to the “Please make a selection” menu over and over again. I liked the way it provided warnings about fingerprinting on certain websites I visit regularly.Ī few days after installing the add-on, I went to online to a commercial website to pay one of my regular monthly bills, and everything seemed fine – no warnings about canvas fingerprinting. Ī few weeks ago I installed an add-on called “Canvas Defender” to Firefox.API differences or about:config edits? Who knows.ĭ, One weird thing is using Canvas Defender in Chromium browsers I only had to whitelist 3 websites instead of the 8 that I had to whitelist in FF. Anyway, it seems like more than half of the websites that I saw a warning on had to be whitelisted because some type of functionality was broken on the site. ‘Blocking’ the data does break more websites, which I was able to see when I used a command line switch (–disable-reading-from-canvas) in Chrome. Canvas Defender doesn’t block the canvas image data it uses a random canvas noise hash instead. I’ve been using Canvas Defender for a few months now and it has a popup warning about possible fingerprinting on maybe 12 websites out of many dozens that I regularly visit, on most websites I don’t see a warning. Just saying, I haven’t completely made up my mind. In version 57 resource URI leaks were taken care of and now with Mozilla continuing the work on reducing fingerprinting it’s kind of getting to be a big deal in my opinion, the privacy improvements.Īctually, I’m not 100% convinced, based on the websites that I visit, that canvas image data is worth ‘me’ being concerned about. Glad to see that they are making some progress on canvas fingerprinting. Make sure it is square (using the viewBox attribute) and you're good to go.I’m not seeing the new prompt in Nightly yet, maybe when I get the next update. Just pop your own SVG (maybe cleaned with Jake Archibald's SVGOMG if you're using a tool) into the const at the top. Var dataUri = 'data:image/svg+xml charset=UTF-8,' + im() It doesn't work on Safari at all though :-( (even to about:blank), it updates the favicon for some reason Google Chrome HACK - whenever an IFrame changes location Basically Chrome allows dynamic favicons, but it only updates them when the page's location (or an iframe etc in it) changes as far as I can tell: var IE = ("MSIE")!=-1 I couldn't get IE or Safari working though.

Here's some code I use to add dynamic favicon support to Opera, Firefox and Chrome. You would then use it as follows: var btn = document.getElementsByTagName('button') OldLink = document.getElementById('dynamic-favicon')

* Dynamically changing favicons with JavaScript The following example might not work in Safari or Internet Explorer. Here is a different demo of code that works in IE11 too. Here’s some code that works in Firefox, Opera, and Chrome (unlike every other answer posted here).
