Firefox userChrome.css Edits

So I've been playing around with a few of these css style changes, only small ones, like removing particular buttons when they are not in use.

My concern is a particular code which extends active tabs. This is fine, unless I open a pinned tab, one of the little small ones that only show the page icon.

/* Make the active tab wider */

tab[selected="true"] { min-width: 200px !important; }

Is there a way I could add in an extra line to except the pinned tabs?
Is there a particular name for them within the code?
Finally, what would introducing an UNLESS function look like.

>I have absolutely no fucking clue if I am even working this right....

Woah, calm down man. Perhaps I may have phrased my original question incorrectly or used a haphazardly worded subject.

If you knew what the code was supposed to be, it might have been easier to write that down and answer my question instead of going on a rant, wasting even more of your time.

I appreciate your sarcasm, but I did expect people on /prog/ to be a little more upstanding than the rest of the idiots I've seen around here.

I do reiterate, "I have no clue." and google is not being very helpful in coming up with results I need that would otherwise save me from posting here.
