However I did run into some "This connection is untrusted" issues with shoddy websites like Apple.com (If you try to download iTunes, it's in a iframe which cannot be added as an exception), this was easily fixed by getting the nssckbi.dll (391KB) from a normal Mozilla installation and putting it in the Light installation folder. I recommend this be done by default in the Light installer.
Another bizarre thing is Light doesn't support HTTPS:// links anymore, it keeps having sissy fits as if the computer date/time is incorrectly configured (and frankly, is my only issue with Light).
I also ran into a bizarre and rare issue with web apps (Shockwave Flash) on another shoddy website http://bingo.williamhill.com/ .
Everything is normal up until you start the game - it opens an unnavigable window with Adobe Flash plugin docked in, loads something then blurts this out:
An error has occurred.
You may need to refresh the application.
Please contact customer support if the problem persists.
Click here to close this message.
Your session has timed out.
After the current game has completed please log back into the application.
Which is very similar to the SSL/HTTPS crap Light has been causing.
Is there a fix for these that can be integrated in the actual installer? It would really make this unofficial build -the- best.
