RELEASES
Version 1.5 (2016-Mar-06) • Updated script-injection technique so that it works also on pages with strict CSP.
Version 1.4 (2016-Mar-05) • Extension was (unnecessarily) trying to patch functions in a cross-origin frame (like Hangouts frame in GMail, Disqus frame in several sites, etc.) from within the outer window. This was breaking the sites’ functionality; now this is avoided.
Version 1.3 (2016-Feb-28) • Blocked iframe[@sandbox] canvas reads are now shown properly inside popup • More detailed information per blocking
Version 1.2 (2016-Feb-27)
