I want to disable manual installation of xpi files in Firefox. Installation from addons.mozilla.org should still be possible. In Firefox 17 ESR it was working fine with the following settings in mozilla.cfg: lockPref("xpinstall.enabled", false); lockPref("xpinstall.whitelist.required", true); lockPref("xpinstall.whitelist.add","update.mozilla.org,addons.mozilla.org");

In current versions of Firefox this isn't working anymore. As soon as I set "xpinstall.enabled" to false, the "Get Add-ons" menu under "Add-ons" disappears and I'm also not able to install from http://addons.mozilla.org

No, this doesn't work. The syntax should be ok. For me it looks like the logic in Firefox has changed in some way or maybe it's a bug and the whitelist isn't interpreted properly.

I can confirm that I also see that the Get Extensions tab is gone if you lock the xpinstall.enabled to false and that this isn't happening in the Firefox 17 ESR version.

  • lockPref("xpinstall.enabled", false);

But I can't install extensions from white listed websites or websites that have an allow exception in Firefox 17 ESR. Installing a Persona works in Firefox 17 and in the current Firefox 32 release with your lockPref() calls.

Note that Firefox 17 ESR is outdated and should at least be replaced by Firefox 24 ESR (24.8.1 is current)

I checked again. In Firefox 17 I'm able to install add-ons from "about:addons" (the "Get Add-ons" tab is visible), but I'm not able to do installations from "https://addons.mozilla.org". For me it looks like a bug in current Firefox versions, as "xpinstall.whitelist.add" isn't working...
