Created a new Firefox profile not too long ago, and after copying over things like places.sqlite, etc, I noticed the following:
The default suggestions when you click the address bar are supposed to be frequently visited sites, and I’ve found it quite useful, but all but two suggestion spaces are occupied by openSUSE related links which I don’t frequent and can’t remove (from shift+del, to nonexistent x to the right of them, and nonexistent bookmarks).
When you have everything checked except shortcuts, you still have search suggestions…
To have search suggestion, you need to type at least one char into the adress bar…
The example I posted was me clicking the address bar, and nothing else. If I disable “Shortcuts” nothing will show up. This is why I’d like to remove those links which weren’t present in my previous profile.
I suspect that’s it. Inspected the package a bit and found among other things browser.newtabpage.pinned in about:config. After clearing that and restarting the browser, the behavior is as expected. Thanks!
