I noticed that when you install an extension that has no button, or a userscript, its pop up balloon that notifies it has been installed is cut off from the screen. Well it’s not a big deal but just sayin’. It would be nice if this gets fixed soon. I think its probably because the chrome wrench button is gone
I moved your post to the bug section as it seems a bug to me.
Could you edit your topic start to meet the requirements for a bug report? This way you will have more chance it will get fixed.
