Rated 3 out of 5 stars

This is a great theme: clean & crisp. Best I've seen. Unfortunately, it has one functional problem: it does not respect the config setting "browser.tabs.closeButtons". I often have dozens of tabs open, and it is very easy to close a tab by mistake when attempting to switch to it. That is why I have set "closeButtons" to zero, which means "show the close button only on the current tab". This theme ignores this setting, and includes a close button on every tab. If this one issue is fixed, this will be the ideal theme (for me, at least).

Chromifox Basic must have close buttons on every tab because it uses a stretched background image across the width of each tab, and Firefox has a visual glitch that will sometimes result in the background image not filling up all the way. There might be 1 pixel across where it appears blank and makes the tabs appear disconnected. So the tab close button must appear to "cover up" Firefox's visual glitch. Believe me, this is not an oversight on my part, I've put a lot of thought into it.

P.S. If you are thinking "other themes don't have this problem", well other themes probably don't use a stretched background image for the tabs. The "overlapping" tabs in Chromifox Basic (that Chrome-style effect) took a lot of CSS hackery that is simply not required with regular tabs that don't overlap.
