Hi guys!
I’ve wrote this code, because I’d like to check if my user has specific extension installed.
let gettingInfo = browser.runtime.getBrowserInfo()
console.log(gettingInfo);
And this is my manifest.json (that is included in my html file)
{
“permissions”: [
“webRequest”
],
“background”: {
“scripts”: [
“browser-polyfill.js”
]
},
“content_scripts”: [{
// …
“js”: [
“browser-polyfill.js”
]
}]
}
My problem is that if I run the html file, I’ve got this error:
browser is not defined
How I can solve it?
Thaks
hello @TheItalianCoder
i did not used the browser extension api before but browser
is exist only on the add-ons extension so it get called by extension not by html or normal js code
check this one if you want to learn more about how to develop an extension
hope that help and have a nice day 
Hello and thanks for the reply.
So, there is no method to check if a user has installed a specific extension, right?
Hello @TheItalianCoder
you welcome
i meant that browser
is only available through the extension api
this what i found
hope that help and have a nice day
