// updated Aug 2017 v1.3.6 Issue with iframe when injected code not called for it due to its late creation same origin.
// updated Jan 2017 v1.3.5 Compatibility working on msedge/safari/opera under tampermonkey. With ie11 (adGuard method) js engine is too old. Windows ok with Chrome either native or with tamper.

// updated Dec 2016 v1.3.0 Bug fixes, check for duplicate selectors, color & other ui issues. Removed zoomer (it used up a little cpu).
// updated Nov 2016. v1.2.3 Iframe handling for deep iframes.
// updated Oct 2016. v1.2.2 Fixed bug, GM menu on Chrome not closing.
// v1.2.1 Adapted for use also in Google Chrome/Chromium web browser.
