The Firebug add-on for Firefox can significantly degrade the performance of web pages. If JIRA is running too slowly (the JIRA dashboard, in particular), we recommend that you disable Firebug.
To disable Firebug for JIRA:
- Open the 'Firebug' pane in the Firefox tab that has JIRA running, by clicking the Firebug icon.
- Click the down arrow next to the 'Net' tab, and select 'Disable monitor' for the URL of your JIRA instance (e.g. jira.atlassian.com)
- Repeat Step 2 on the 'Console' and 'Script' tabs.
