NTB is not compatible with FireFox 41.0

Hi,

My questions are:

1- Norton Toolbar version number  under add-ons shows as 2014.7.12.35  in FireFox, however, in Google Chrome, shows as 2014.7.12.30 , and in MS IE, shows 2014. 7.12.28.  However, the version number of the Product (IDSS) shows as  2014.7.11.42. 

 NTB is not compatible with FireFox 41.0, however, it is compatible with Google Chrome and MS IE.

Whenever I run the LiveUpdate of IDSS many times, but neither the version number of product IDSS got updated, nor did the NTB version number  get changed/updated. I.e  the version number of product  IDSS remains 2014.7.11.42.  And the 

 

2- Why always does only the NTB version number get updated/changed, however, the version number of product IDS remain 2014.7.11.42. ?
