@skichic95 let's see if we can figure this out. I have a working version of 3.5 and it looks like you are using WordPress 3.5 so we may be able to figure out what is different. I'm willing if you are.
When you get that kind of error in javascript it can mean:
- Another script is causing a conflict with it. This is the most common cause with core WP scripts in my experience.
- There is an error in the script itself.
To rule out number one, we can compare the javascript scripts that you are loading with what one of my installs that's working is loading. You could use a file-comparison program like Meld to do this quickly for the longer sections of code. To do this, go into the admin side and Posts -> Add New in Firefox. Then hit Ctrl + U to view the source code (or Tools -> Web Developer -> Page Source). Here's the javascript on my site.

If you're loading any other javascript than those, or the javascript you're loading corresponding to those differs other than in the UID or the domain name, then you may have found the source of a conflict. Let me know what you find.
If that doesn't find the culprit, the next thing to do would be to see if we can find an issue with the actual code. To troubleshoot that, rename your wp-includes/js/quicktags.min.js and save the following (the contents of my working file) as wp-includes/js/quicktags.min.js, then clear your browser cache and re-test:

If that doesn't work, the next thing is to see if we can get a better idea of what the actual error is, which a minified file makes very difficult. To force WP to load the non-minified versions of the javascript files it uses, go back to your wp-config and add:
define('SCRIPT_DEBUG', true);
Log out of WP. Clear your browser cache (Ctrl + F5 in Firefox) and log back into the admin side of WP. Repeat the steps you use to see the javascript error in Firebug. If we're really lucky, it won't happen in the non-minified version of the script, but if it does, we should get a more helpful error message.
Let us know what you find.
