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)

It blocks Excel for Office365 workbooks from running in Chrome and there is no toggle to disable for specific sites, so guess I'll just delete the extension
