Jira header drop downs (Projects,Issues, Agile) not working in Chrome/Firefox

[Courtney German]

Overnight it appears that the drop down menus for Projects, Issues, and Agile have stopped working on Chrome and Firefox for our server version of JIRA. They work fine in IE but our developers are heavy Chrome users. Confluence and Stash are working properly in Chrome and Firefox. Any advice for troubleshooting? i have googled the issue and not had alot of luck finding an answer.

What has changed? What is your JIRA version? What is your browser versions? 

[Courtney German]

To my knowledge nothing was changed overnight other than JIRA restarting per usual. We are running version 6.2 and have Chrome 49.0.2623.112 m

Odd. Anything unusual from the browser logs? No new add-ons installed? Can you try running in safe mode?

[Courtney German]

I tried safe mode and had no luck. No new add ons and nothing noteworthy in the log

[GabrielleJ]

Both the browser logs and application logs? Hmmm. There must be something that change. Any other system admin that might know?

[Tiffany Lancaster]

Both admins are equally stumped.  IE works fine.  Chrome and FireFox do not work.

• We have tried everything out of this: https://confluence.atlassian.com/kb/browser-troubleshooting-guide-330796533.html
• We have asked out security and networking teams here if anything was changed over night and it was not.  

We are now opening a case with Atlassian.

Ok. Sorry if I could not help. Usually when I troubleshoot this issue, it's usually:

• Some particular add-on
• The IT Infra team have pushed some mandatory changes to the Browsers (Like adding a proxy)
• Firewall and Security changes
• Browser version upgrade (automatically being upgraded)
