Interesting Firefox extension – Nightly Tester Tools

Most important factor I like about Firefox browser is its extensions.  I had installed over 40 extensions on with my browser.  But whenever I planned to move to new beta version, there is a pain in making most important extensions work on the new Firefox beta. 
This time, I came across a Firefox extension called “Nightly Tester Tools“, which helped me in getting most (99%) of my extensions to work with latest beta.  Its operation is simple and straightforward.
