Thanks for the information, Achal Dave Rated 3 out of 5 stars

Your attitude is the smartest, Achal Dave, that is trying to find out the extension's purpose rather than nagging :)
This said, perhaps I'd tweak the code's content to make it replace "I love Chrome" by "I love Firefox"
That brings me a big laugh !)

This review is for a previous version of the add-on (Beta.1-signed.1-signed). 

No shared future ! Rated 1 out of 5 stars

In the future I won't be installing this add-on, unless :
1- It includes a description which would allow me to believe the author does not rely on twilight zone effect to look smart,
and, or
2- The add-on include coffee, toast and marmalade.
