= Quick Summary =

The following document quickly illustrates how to remove the '''experiments.json''' file if there's issues installing the experiment. Regenerating a new '''experiments.json''' file should be the first troubleshooting step taken if there's any issues. Once Firefox is re-opened and reads the experiments manifest, a new '''experiments.json''' will be generated in the same location.

''' Note:''' The profile directory on your computer might differ depending on your username/environment but should be very similar to the following examples:

* '''Windows:''' C:\Users\<current user>\AppData\Roaming\Mozilla\Firefox\Profiles\nae12udp.default
* '''OSX:''' /Users/<current user>/Library/Application Support/Firefox/Profiles/y35f3ueg.default
* '''Ubuntu:''' /home/<current user>/.mozilla/firefox/ezbdnu88.default/

Once you've deleted the current '''experiments.json''' file, re-run the browser and disable/enable '''experiments.enable''' under '''about:config'''. 

You could also use the following commands inside the browser console to force a refresh:

* Import '''Experiments.jsm''' into the browser console:
** '''Cu.import("resource:///modules/experiments/Experiments.jsm");'''
* Force the refresh inside the browser console:
** '''Experiments.instance().updateManifest();'''

You should see some logs being dumped into the browser console and '''experiments.activeExperiment''' should appear as '''true''' if the experiment was installed.
