SubscribeFirefox 1: ”Software installation is currently disabled”
Posted on Nov 18, 2007 under Firefox Tips |Software installation is currently disabled error, Click Edit Options… to enable it and try again. You click Edit Options and there is no option to enable software installation. Here’s how to fix it.
Since the option to enable software installation no longer exists in the UI, you will need to use about:config to reset the xpinstall.enabled preference to the default true value.
1. Type about:config in the Location Bar and hit enter.
2. Type xpi in the Filter box and find xpinstall.enabled in the list.
3. Make sure its value is set to “true” (double-click will toggle).
