Mozilla has served its 2 billionth Firefox Add-on download. The download rate has been increasing each year, but Firefox also faces increasing competition in the open source browser market.

This week Google actually took efforts to make Chrome more accessible, and introduced a new category of featured extensions.

Mozilla’s milestone is certainly a significant one though, and there’s no question that Firefox has been revolutionary in the web browser space.

Digg has launched new extensions for the Mozilla Firefox and Google Chrome web browsers.

Video search engine VideoSurf launched a Firefox add-on today called "Videos at a Glance," which can show Twitter users the videos behind applicable links. For example, if someone in your Twitter stream posts a link to a video, the add-on will automatically display the video, as well as a visual video summary, right in the tweet, so you don’t have to click through.

Last month Google spoke about an initiative it was kicking off to call upon webmasters to help make the web faster. Larry Page once said he envisioned a web that could be surfed as easily as flipping through the pages of a magazine. This initiative is kind of an extension of that way of thinking.
