change ui fonts on toolbars without affecting web page text

I've pretty much exhausted my simple little mind about this problem. At some point around the beginning of the year, Firefox changed the fonts on all my toolbars to some ridiculously miniscule font. I've queried Google's AI several times, tried every solution I've received, all to no avail. Is there a way to do this? I just want to enlarge the font in all the toolbars, not the web site contents, and lock it in. Thanks to whoever can help me achieve this.

Maybe is there a solution possible with CSS code in userChrome.css.

Thank you cor-el. I got to the point of making the userChrome.css. and userContent.css files, but don't know a thing about adding code to them, or which to add it to if I did know. Again, thanks for your help. Think I'll go back to writing, and mailing letters as my communication method.

1. Create the file in the chrome folder, which you may have done.

2. The First/top line must be

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

3. Here is an example code for the nav bar, from my site. I only set the size, not the font


/* ------- NAV BAR ------- */

  1. nav-bar {

height:32px !important; font-size:1.32em; margin-top:-14px !important; padding:0 !important; background-image: linear-gradient(#660099, #9933ff, #450078) !important; position:relative !important; z-index:10 !important; }


I will leave you to play and add the font :)
