User Agent: Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130215130331 Steps to reproduce: I install Avira with Web Protection. It's offer me Avira 4 SearchFree Toolbar which look like http://search.avira.com/AVR-4/launch.html?locale=en_PL . It caused that 'Undo closed tabs' were disabled - greyed out. Shortcut (Shift+Ctrl+T) doesn't work as well. I reinstalled operation system - Windows 7. It's impossible that reason of this bug was outside of Mozilla Firefox. I checked all browser options like - save browsing history. I was saving. After I removed Add-ons Avira Toolbar and I uninstall Avira. "Undo closed Tabs' start works again. Actual results: 'Undo closed tabs' were disabled - greyed out. Expected results: Feature was disabled. It should work. It should switch on last viewed pages.
Avira 4 Search Free Toolbar is a third-party application, and Mozilla can't fix it. If this application brokes some Firefox features, ask Avira's support to fix its product.
