Google was able to make for Chrome beautiful concise design. Moreover, they placed tabs at the very top of the window, while removing the header line occupying a lot of space. I was immediately amazed at the opportunity to pull tabs out of the window, and when Firefox 3.5 came out, I was extremely happy with a similar feature with him! And now I have a question, what if I set up Firefox so that it looks and behaves like Google Chrome!
I found several solutions, they are presented below:

According to the author,
Chromifox Basic is currently minimally configured for Firefox 3.5. Nevertheless, everything looks good and can be used as a permanent skin.

Chromifox Extreme is a more elaborate theme. In contrast,
Chromifox Basic places tabs above the address bar. Skin was inspired by the
Chromium project. The author advises to put
Chromifox Companion to complete the transformation of Firefox in Chrome.
Of the minuses: I personally did not like not getting into the color of the active tab in the color of the window ...
Chromin Frame puts tabs on top and replaces the frame window and title creating a complete copy of Chrome! However, add-
ons are skin independent and can be used with
Chromifox Basic , for example. Optionally, you can put all the same
Chromifox Companion .
But there is one big "BUT". Chromin Frame is not compatible with Firefox 3.5. But, as they say, if you really want something, you can: download and put the
xpi-file fixed by me :) Skin has some visual bugs, but the main functionality works.
Enjoy your web surfing!UPD : You can put the
DEV version of Tab Mix Plus , but at your own peril and risk. (Thanks,

UPD2 : You can consider
Total ReChrome and
ChromiGlass , but they are not yet compatible with FF 3.5 (Thanks,

UPD3 : Here's another interesting add-on for the fox called the
Chrome Package , but at the moment it is not compatible with FF 3.5.
