Chrome Package (for Chrome look and feel)
Speed Dial (Chrome like most visited site)
Distrust (Private browsing or Incognito)

To download Chrome Package, you will need to register and login. After downloading, installing the add-ons and restarting Firefox, you will be greeted by the Chromified Firefox. Note that, in the “Chromified Firefox” screenshot, I have hidden the Firefox toolbars (like Google, Bookmark and other toolbars) to make Firefox look alike as much as Chrome

Note that these add-ons make Firefox look similar and function partially like Chrome. Do not expect the same look and feel and exact functionality/features.

Chrome Package
This add-ons brings in the Chrome look and feel to Firefox. Note the tabs going above the location bar, change of icons and the + icon besides the latest tab to open a new tab.
Windows Vista users can try the Total ReChrome addon, instead of Chrome Package. This add-on requires another add-on called Chromifox to be pre-installed. I found it while searching for Chrome add-ons and I haven’t tried it myself. This add-on does not work in Linux.

Speed Dial
This add-on shows the most visited site when a new Firefox window or tab is opened. After a Firefox restart, Speed Dial’s configuration pops up. On this, I checked/selected the following options:

• Load in blank new windows
• Load in blank new tabs
• Set Speed Dial as home page

Note that unlike Google Chrome, Speed Dial does not automatically display the most visited site. You will need to bookmark your favourite sites via Bookmarks>Set as Speed Dial.

Distrust
This facilitates the private browsing or the Incognito mode in Chrome. You may like to read about its functionality here. It displays an “eye” like icon on the right side of the Firefox’s status bar. Clicking on the icon shows a green tick and starts the private browsing. From here on, any URL visits, form fillups, download history etc, are not stored. Note that, in Chrome the private browsing is started by launching a new window called the Incognito window. Hence Distrust gives similar features but not the same functionality.

I found the first two by searching for “chrome” on the Firefox add-on site. Found Distress by searching for “private browsing”. If you are able to find more, let me know
