This extension lets you enter a JIRA issue key and opens a new tab to that issue
Tired of navigating to Jira issues by finding an old one in your browsing history and editing the number every time? Use this! Just set the root URL and project prefix, and then quickly open any issue by entering just the number. Issues will open in a new tab. Hurrah, microseconds saved!
