Hello:
I need one chrome extension in CRX format for Windows 10 (Version 21H2).
My current chrome browser version is: Version 103.0.5060.114 (Official Build) (64-bit)
When I tried to load your extension, I got warning from Chrome developer tools, the version 2 is depreated, so I changed it to use version 3, like the following:
{
"name": "Ad Blocker",
"description": "Blocks ads on any website",
"manifest_version": 3,
"version": "1.01",
"background": {
"scripts": ["blockedsites.js", "script.js"]
},
"icons": {
"128" : "logo.PNG"
},
"permissions": ["webRequest", "webRequestBlocking", "http:///", "https:///"]
}

Then, this time, Chrome developer tools directly refused it with the reason:
The "background.scripts" key cannot be used with manifest_version 3. Use the "background.service_worker" key instead.
Could not load manifest.
I learned the extension for a few days last year, but I didn't encounter such issue, as last year version 2.0 was OK.
But for the time being, it seems version 2.0 is not OK any more.
Can you please modify your code to use "background.service_worker"?
Thanks,
