It is useful for developers, analysts or testers who often need to open JIRA issue using its key.

Getting started After extension is installed you need to define URL of your JIRA in the Options page. After URL is defined open extension, insert key of issue (case insensitive), click Enter and extension will open required issue in new tab. * Spaces at the end and beginning of the inserted key will be trimmed * Skype formatting ([DATE] NAME: issue-key) will be trimmed If you have only one project and want to insert only numbers without project prefix, then you can try to use other extension URL With Parameter Opener - https://addons.mozilla.org/firefox/addon/url-with-parameter-opener You can use URL like "https://jira.atlassian.com/PROJN-" there.
