Ok, fair enough. Before I wrote my comment, I did perform a "view source" to search for "ad-free internet" and it wasn't found. However, if one uses F12 Developer Tools to inspect the DOM, it does have:
"<title>Ad-free Internet by Firefox</title>"
It's interesting that that phrase is not visibly used and the big bold text people actually see just says "Support the sites you love, avoid the ads you hate".
EDIT to the replies: Yep got it. I can't see the title text on any tabs because they're too narrow when I have 50 tabs open.
Yes but the HN guidelines also lets the submitter use some judgement if the title is misleading:
>Otherwise please use the original title, unless it is misleading or linkbait; don't editorialize.
But I'm not going to nitpick this thread's title. If "Ad-free internet" is the best representation for HN readers because Mozilla itself used it, that's fine too.
