Add my Blog to HSTS preload list

Now my Blog, David Yin Blog is https encrypted . And it is also HSTS enabled. And latest, it is HSTS preload enabled.

It has three layers meaning.

  1. https support.
  2. HSTS enabled.
  3. HSTS preload enabled.

Let me explain them one by one.

First, add https support. I did this step on Feb. 2016, when I announced that SSL added. I recorded how I get the SSL certificate and install it on Nginx web server.

After that, all content send back and force from my Blog to an audience is encrypted. Even ISP can not read the content from the data traffic.

Second, I add the HSTS into the Nginx configuration, to make it more secure.

It allows web servers to declare that web browsers (or other complying user agents) should only interact with it using secure HTTPS connections,[1] and never via the insecure HTTP protocol. HSTS is an IETF standards track protocol and is specified in RFC 6797

Firefox 9.01 release

Time goes so fast. And also version number of Firefox.
Today I saw Firefox 9.01 released. Actually it is released yesterday, Dec. 21, 2011.
Just one day after the Firefox 9.0, which is released on Dec. 20, 2011.
Firefox 8.0 released on Nov.8, 2011.
Is it a number game. To mimic Netscape Navigator.
I do hope Mozilla Firefox can improve the loading speed and fix the memory problem in the soonest future.
Google Chrome has better experience now. The only reason I still use Firefox is the plugins. Firefox has a lot of third party plugins.

Browsers battle in 2009

Now there five main browsers in the market.
Apple Safari, Google Chrome, Microsoft IE 8, Mozilla Firefox, Opera.
If we just think about Windows platform.
Firefox has best web application compatibility. For web standards, Google Chrome and Opera are better support standards. Everyone knows that Firefox has a lot of Addons. So for extensibility, Firefox wins.
There are also some very important for users.
Performance, Opera 10 and Google Chrome are loading faster than others.
Platform Support, Firefox and Opera support Windows, Mac and Linux systems.
I do have IE on my Windows. I have Opera and Firefox too.
Among these three, I use Firefox most often, because of addons I need only working on Firefox. Sometimes I use Opera. Opera Unite is very cool.
What happen in next year.
