Firefox has released the version 4 with several new features and the EasyBM plugin (add-on) has been updated too. You can download the latest EasyBM plugin for Firefox here.
Clicking on the link will let you download and install the add-on. In case, Firefox wants to save the file, let it save and then execute the file through Firefox. It will install the add-on and prompt you to restart Firefox. This plugin is very easy to install and lets you bookmark the page you are currently browsing. Just click on the bookmark icon in the right side of the status bar and a pop-up window will open up. Choose the group where you want to add this site and edit the title and description. A simple click on “Save Bookmark” will save it for you.
