I'm trying to port a Chrome extension to Opera.
In my chrome manifest.json I have the following lines which tells the Chrome browser to use a specific html page when it launches and whenever it opens a new tab.
"chrome_url_overrides" : {
"newtab": "my-page.html"
},
How would one create this same action in Opera? I looked at the Browser and Page actions but they don't seem to do the trick.
