Chromifox, called “coat of Chrome for Firefox”, is a bright and soft blue theme for Firefox 3 on Windows, Linux, and Mac OS X, inspired by the appearance of the Google Chrome web browser. Chromifox gives Firefox the almost Chrome like appearance except the tab bar and title bar which is fused into one in Chrome. This is fixed by another addon called Total NoChrome.
Total NoChrome is a modification of the Total ReChrome addon which places the tab bar at the top and changes the appearance of the title bar bringing it closer to the Chrome look.
That will take care of the looks. Now for the functionality. To get Chrome’s features in Firefox, get the following extensions.
4. Locationbar2 to highlight domain in address bar.
5. New Tab Button on Tab Right to put newly opened tabs next to the parent tab.
