Rated 5 out of 5 stars

I'm using Firefox 36.0, I remember from Firefox 35 or maybe early version, this add on does not works. It will disable all the flash window. Today, I found a solution from the focus-regainer-lite's review, and you need to add bindToUntrustedContent="true" in the focusregainer.xml file inside the XPI file. After change that, this add on works fine now. The detailed modify should be follow this link: https://addons.mozilla.org/En-us/firefox/addon/focus-regainer-lite/reviews/654988/

This review is for a previous version of the add-on (0.4.1-signed). 

fixed in version 0.8
