Mozilla has had a change of heart regarding opportunistic encryption—for now. The company rolled out its open-source Firefox 37 Web browser on March 31, with one of the key new features being a capability known as opportunistic encryption. However, due to a security issue related to opportunistic encryption, Mozilla disabled the feature in the Firefox 37.0.1 update released April 3.
The security issue is located in Mozilla's HTTP Alternative Services (Alt-Svc) implementation, which is connected to the opportunistic encryption capability.
If you want to find out more about the security of a connection to a particular website or a request that a site made while it was loading, then it is quite difficult to do so right now in most browsers.
While you can look up protocol information if https is used with a click on the lock icon in the browser address bar, and go from there to retrieve additional information, it is taking quite some time to do so.
Since 2004, Google has been paying Mozilla a ton of money each year—estimated at around $100 million—for the privilege of being the default search engine used in the Firefox browser. This contribution represented the lion's share of Mozilla's income, something in the ballpark of 85 percent.
Mozilla today pulled out the PR stops to trumpet the 10th anniversary of Firefox, and in celebration released an interim build of Firefox 33 that includes a new privacy tool and access to the DuckDuckGo search engine.
Firefox 1.0 was released on Nov. 9, 2004, at a time when Microsoft's Internet Explorer (IE) had a stranglehold on the browser space, having driven Netscape -- Firefox's forerunner in many ways -- out of the market two years before. Mozilla has been widely credited with restarting browser development, which had been moribund under IE.
