I upgraded from my former extensions to Data Bridge 1.1.3. I uninstalled all the other extensions first.
The only extensions currently installed and active are:
Data Bridge 1.1.3
Pro Maps for Google 1.0.7
WebAssist Free Tools 1.0.2
Installed but not active:
Social Media Tool Kit 2.0.0
SiteAssist Professional 1.0.9
They're using gmail professional or whatever it's called.
