My website works in Chrome, IE, and Safari, but when I load it in Firefox, Firefox complains saying "window.controllers is deprecated. Do not use it for UA detection." This code is in the OpenLayers API (OpenLayers 2, latest version), so I can't change it. Is there something I can put into my code so that it'll work in Firefox?

    According to [this forum post](https://pyd.io/f/topic/latest-firefox-33-0-2-update-not-working-with-my-pydio-5-2-5-server/) it was broken in FF 33.0 on Windows and Ubuntu, but fixed in 33.1. Have you updated to the latest version? – Rhumborl Dec 08 '14 at 23:05
  • I tried but it didn't help. – user3148225 Dec 09 '14 at 02:27
  • This issue still exists for FireFox 37.0.1. A console error "window.controllers is deprecated. Do not use it for UA detection." is thwon up even for a very simple js page – MarcoZen May 04 '15 at 11:12

That's because of your medieval firefox extension you have installed. LiveHTTPHeaders in my case.

    Just out of curiosity: do you still use LiveHTTPHeaders or have you found one that doesn’t throw this error? – Manngo Apr 25 '17 at 04:17

    I don't know if I'd call it "medieval". It's still a handy extension from time to time - especially whenever I need to follow the entire conversation through a zillion redirects, which is something the Firefox Network tab doesn't do without altering the browser's configuration. Google Chrome does temporary persistent network tracing better via a nice toggle button on its Network tab. The best solution in my case is to leave the extension installed and ignore this warning since it's not actually an error. – CubicleSoft Apr 28 '17 at 04:37

You may just need to visit about:config and set the loglevel to all

Please refer to all options available in config here
