Second, I dono if somebody else has already reported this...
I tried installing Stumble on my yet unupdated Mozilla 220.127.116.11.2
It kept saying "Software installation is currently disabled. Click "edit options" on the right, enable it and then try again"
And it gave me a small edit options box...Clickin on it produced the "Contents" tab in Mozilla's preferences box. That didn't help too much. So googled it up and found the following :
Enabling software installs
Some users may have disabled the software installation option based on security issues which have since been resolved . To re-enable:
Firefox 1.5: If you previously disabled this option and then updated to Firefox 1.5, the disabled setting will be carried over. Since the option to enable software installation no longer exists in the interface, you will need to:
- Type about:config in the Location Bar and hit enter.
- Type xpi in the Filter box and find xpinstall.enabled in the list.
- Make sure its value is set to "true" (double-click will toggle)
You mite find some other raw config options in "about:config" ;)
