Good but... Rated 3 out of 5 stars

This is a really good add-on, no doubt about it, but....

There is one glitch that is REALLY annoying; on some web pages the whole tab bar becomes transparent so the top of the web page is at the top of the screen, and you can't click on the links at the top of the web page - seriously annoying!
Sometimes refreshing the page helps but not always. Fortunately, this doesn't' happen often enough for me to ditch the add-on altogether - but it still does my head in every time :(

PLEASE FIX...

Thanks

This review is for a previous version of the add-on (7.1-signed).
