Huge problem Rated 1 out of 5 stars
In CSS panel, Ctrl-Z doesn't work anymore, if you :
Open the CSS editor.Make some change. At this stage, CTRL-Z is still working, till you don't click outside the panel.
Click anywhere on the page content.Click on the CSS editor tab, try a Undo, it doesn't work....
Neverending problems with that extension since the big 1.2.1 update.
