FF Bookmarks Toolbar Size

Can someone tell me how to change the size of the font in Firefox's bookmark toolbar. I've been customizing a theme and can't see where to change this. It's too big atm.

Are you familiar with userchrome.css?

If so, place this line inside of it with the font size you want:

#PersonalToolbar .toolbarbutton-text {
font-size: 15px !important; }

Customizing Mozilla

I'm not familiar with that.
Is that really neccessary anyway? I must be able to change it the same way I changed the theme (can't think of the name of the software I used because I'm at work and don't have it here ) because it was after changing the theme that the toolbar got this big

Yeah, UserChrome.css is the best way to customize firefox. It's a lot more configurable than a program. It's kind of like comparing a WYSIWYG web editor vs a Plain Text Editor. Here's how to find and use UserChrome.css

%USERPROFILE%\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxx.default\chrome\

Open userchrome-example.css
Add the lines you want
Save as userchrome.css

Your theme software will can and will change most of the stuff you can change in UserChrome.css but there are times when the program itself doesn't have the option. UserChrome has every option except for the image theme stuff.

Didn't do anything. I created a file userChrome.css, put it in the Chrome folder but nothing.
#PersonalToolbar .toolbarbutton-text {
font-size: 12px !important; }

edit: Got it!!
