Reproducible: Always Steps to Reproduce: 1. Begin with two tabs open, A and B, and with the leftmost, A, tab active. Close A tab, leaving you with only B open and with the tab bar hidden. 2. Open a new tab, C, by cmd-clicking a link in B. If this link fails to load due to the connection to the web server times out, when you close B and view the striped empty C with the Mozilla-logo indicating that the browser tries to load the page you cannot open a new tab by using the keyboard shortcut for it (cmd-t). However, you can use the menu option to create a new tab. 3. Actual Results: The keyboard shortcut stopped working. Expected Results: Accepted keyboard shortcuts as usual. This frequently happens a versiontracker.com. I have privoxy installed and enabled most of the time, but disbling privoxy does not make any difference.

This could be a dupe of Bug 110718, which in the meanwhile has already been fixed. Reporter, can you still reproduce this using recent builds? Prog.
