Now the only reliable way is through multiple keystrokes (ctrl+k tab). This is both non-obvious, and tedious. It would be good if we had a shorter keyboard shortcut sequence to focus the current tab, or some other method. Tab focus is required to use some of the tab related keyboard shortcuts http://support.mozilla.com/en-US/kb/Keyboard+shortcuts Reproducible: Always Steps to Reproduce: 1. Mouse click on a tab 2. ctrl+k tab Actual Results: After step 1, the tab did not gain focus After step 2, the tab did gain focus Expected Results: Previously, both steps would result in the tab being focused.
This seems basically Bug 491178.
(In reply to comment #1) > This seems basically Bug 491178. Same root cause, yes. This Bug however is more generic and to the point.
