firefox 88 will have http/3 enabled by default.
Yes, that’s what the article says in the very first paragraph.
I m using firefox 88 but site getting served on http/2 still.
For starters, most sites won’t support HTTP 3 yet. Plenty of them don’t even support HTTP 2 yet.
Also, from the way it is phrased it seems they will slowly roll it out as default with version 88, but it probably won’t be available everywhere before end of May.
