Mozilla has announced that they will dropping the support for regular HTTP protocol. They will only support secure HTTP (HTTPS). Altough this announcement is not followed by clear timetable, but it’s likely that will take a long time.
Richard Barnes, Firefox Security Leader said the move from HTTP to HTTPS will be done in two major steps. Firstly, a date will be set, after which all the new features will be made available only for websites that have adopted HTTPS. Secondly, some browser features will be phased out gradually for non-HTTPS websites.
The decision to move from HTTP to HTTPS should have been made a long time ago, but the inertia of the Internet is very huge and painful. Most websites is still using HTTP.
