Homepage override unexpected behavior

Got it. And upvoted.
And yes I was facing it in Firefox 62 as well.

Here’s the code I used as a workaround in my background.js:

function loadStart(){
    browser.tabs.update(
        {
            url: "index.html"
        }
    )
}

browser.runtime.onStartup.addListener(loadStart) // does not fire in private browsing, not recommended

function pushStart(data) {
    if (data == null) {
        loadStart()
    }
    else {
        // console.log("tab is well defined")
    }
}

var currentTab = browser.tabs.getCurrent()

currentTab.then((data)=>(pushStart(data)))
