We got a review from Firefox Addon team that when they build the source code they are getting a different file from the one that we generated useing the codespace in github. Looking the hash and filesize they are correct, there build is different.
Need to investigate why they are different and how we can avoid this so that our version in firefox is approved.
Build folder we uploaded:

build the firefox review team generated.

Need to understand what and why it is different.
Sidenote: Perhaps we will just upload the addon file they gave :-D
