With Firefox sync you can easily pick up from where you left when using Firefox from any other device. To take advantage of Firefox Sync, you need a Firefox Account.

Firefox 16.0.1

Mozilla discovered a security vulnerability in Firefox 16 and temporarily removed it from current installer page a day of releasing it. It also advised Firefox 16 users to downgrade to the 15.0.1 until a patch is released. According to the Mozilla Security Blog, the security flaw responsible “could allow a malicious site to potentially find which websites users have visited and have access to the URL or URL parameters”. Now that Firefox is patched, users will be automatically updated to the patched 16.0.1 release.

Firefox 14.0.1

In Firefox 14.0.1, the default search engine of Firefox, Google Search, started using HTTPS connections when you search using it. OS X Lion users were able to enjoy web browsing in full screen. With 14.0.1, just like Google Chrome’s “Click to Play plugins” feature, Mozilla implemented “Click to Play” feature for Firefox. The new “Click-to-play” feature (disabled by default) will disable plugin (such as Adobe Flash) when you are loading a page. Later, if you want to load the contents of that plugin, you can activate them with a single click on the area. Mozilla has still kept “click to play” and “in-content preferences” features disabled by default. If you need these features, you will need to manually enable them via the about:config preferences.
