I was in the browser options in Firefox and I noticed a blue link across the top: Your browser is being managed by your organization. These messages usually mean some kind of restriction has been put in place. But by whom and why? It turns out it was Avast antivirus. If you have the same situation and are having trouble changing Firefox’s settings, here’s how to remove this.
Removing The Registry Key
You’ll need to delete a Registry Key. So open the Registry Editor. In the Start menu, type Regedit and open the Registry Editor. Allow any security prompts, then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla. The easiest way to get there is to copy and paste the following line in the Address Bar in the registry editor and press Enter. That will take you right to the key:
Right-click on the Mozilla key and delete it. If you want to back up this key, first click on Export, otherwise click on Yes when asked to confirm the deletion. Restart Firefox or do this with Firefox closed and then this message is gone. As I was writing this, my Avast application updated and replaced these restrictions again. This was an Application update and not a Definition update.
It’s your call how you want to go about this. If you have no problems changing options or don’t even bother with such things, it won’t hurt to leave it as long as you know where it comes from.
If you know exactly what is blocked by these restrictions, we would appreciate it if you shared your experience in the comments below.
