Removed few false positives

Refined code to improve detection and reduce false positives

Refined detection mechanisms to improve results.

Added an option to alert the administrator about the suspicious websites being browsed based on website behaviour. The add-on continues to give alert message and thick red border to all such websites.

Dear Users,
A new feature has been added in this version.
A custom blocklist maintained by me will be fetched by the Add-on and all browsing requests to such websites will be blocked.
So as a package, the Add-on will continue provide warnings to the pages which seems suspicious based on behaviour and for confirmed threats, users will be blocked from accessing the same.
