I have found that the extension for Chrome doesn't close after opening a new site from it. Instead, when I go back to the tab in which I accessed the extension window, it remains exactly how it was when I hit Return. I tried installing the Chrome Web Store version to see if that would make a difference, but it has the same issue.
Obviously this isn't a huge deal, it's just a nuisance that I'd rather not have to deal with. This issue does not exist in Firefox nor Safari.
I'm running OS X 10.6.8 and 10.7.4, and it occurs on both machines.
Thanks for your help.
