"Disable reading from HTML5 canvas" breaks extension icons
Posted: Tue Feb 16, 2016 2:53 pm
When "Disable reading from HTML5 canvas" is turned on, extension icons are frozen and can't be changed.
The best example I have is LastPass. Normally, the LastPass icon changes from Gray to Red after you log into it (change icons I believe). When the "Disable reading..." feature is turned on, the icon never changes no matter what. Whatever icon you see in the browser before you turn on "Disable reading.." is the one you are stuck with. I suspect there is some JS code they are using to change icons after you login and this breaks that. I also see it affecting uMatrix as well.
