The company Mozilla, which is the developer of the browser Firefox, in his blog said phaseout of support with sites using a secure protocol is not HTTP. In the first place not on a secure site will not work all the new functions of the browser, as well as those functions that browser developers deem dangerous.
Recall, earlier made a similar statement and the company Google, adding that the sites using HTTPS will be ranked higher in the SERPs is not secure sites.
This is due to the fact that the HTTP protocol is outdated in terms of security and the entire transmitted between the user and site information can easily be intercepted and read by third parties.
Thus the global giants have decided to gradually fully translate the entire Internet on a secure protocol HTTPS. Therefore, it is possible that in the near future by opening a website in your favorite browser you'll see a warning that your site is not secure .
