Part of the plans Mozilla mentions have already been achieved in Firefox 10 and 11. To resolve problems with old add-ons not working in (now very frequently released) new versions of the browser, they were made compatible by default. Also, from Firefox 11 you can now also sync add-ons across several computers.
However, the full Firefox roadmap reveals several other important updates planned for later in 2012.
One that caught our attention is silent updates, which will be downloaded and installed silently in the background, without the need for user intervention. This feature is planned for Firefox 13.
Another interesting feature coming later in 2012 is the ability to share links and updates to a variety of social networks directly from the browser. We've seen products such as (now discontinued) Flock try to integrate social networking directly into the browser, but none have been able to catch a significant market share.
Which of Mozilla's plans for Firefox do you like, and which seem like bad ideas to you? Are there any features you'd like to see in the next iterations of Firefox? Share your opinions in the comments.
