Oh, probably because I didn't sign it, try this manifest then
{
"manifest_version": 2,
"name": "Free SMS Texting",
"version": "2.0",
"default_icons": {
"18": "/images/icon19.png"
},
"set_action": {
"default_title": "Texting",
"default_popup": "index.html"
}
}
And that Also, If you don't use chrome or have problems I might have mentioned it already but
you can go to http://annoyingcalct1.site50.net/ for the same thing
