How to uninstall included web developer app in FF 28.0?

more options

The included web developer program in FF 28.0 will turn itself on. This usually happens when I am on the phone and need to view the web page. I cannot close it's window so I would like to disable it permanently. How do I do that?

You expose your system to security vulnerabilities by running such an old version of Firefox.


The issue could be caused by one of your add-ons. Restart Firefox with Add-ons Disabled to check if that's the case.

If the problem goes away in Safe Mode, you can either try to determine which add-on is to blame, or you can Reset Firefox and get rid of them all.

If the problem persists in Safe Mode, please attach a screenshot of it.
