"Disable reading from HTML5 canvas" breaks extension icons

Post by SuperValue » 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.

Acknowledged in a previous bug report link here
I'll move this Topic to Known Issues forum as it was acknowledged in September.

This setting locks the icons into whatever state they are in when it is set. Affected are icons to such extensions as Lastpass, ublock, gmail notifier, etc. This has been in effect over the last several SJ versions.

Actually this problem is supposed to have been fixed a while back. Are you using the latest version?
