I'm doing userchromecss customization of firefox 3.0.19 on slackware linux 12.2 and none of the css lines I've tried would ever change (in size and style) the font inside the hover box. I've tried same css lines on thunderbird and seamonkey and they work, but not on firefox. Here are the css lines I've tride:

    */ set text font of hover box */
    .tooltip:hover {
        font-size: 9pt !important;
        font-family: Tahoma !important;
    }

Result : no change in tooltip font

    */ set text font of hover box */
    .tooltip {
        font-size: 9pt !important;
        font-family: Tahoma !important;
    }

Result : no change in tooltip font

    */ set text font of hover box */
    tooltip {
        font-size: 9pt !important;
        font-family: Tahoma !important;
    }

Result : no change in tooltip font

...and more , but still no change in tool tip font.

This code work for me in 3.0.19 and 5.0 (haven't checked the others, but should work there as well)

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
tooltip:not([id="aHTMLTooltip"]) {font-size:18px!important}

Does other code in the file userChrome.css (name is case sensitive) work?

Thanks. I tried your code but it only affects the tooltip font of "Getting Started"-tab. The buttons along the navigation toolbar (i.e., back arrow, forward arrow, reload, stop, home including those on the url bar and the search bar have their tooltip font remaining unchanged. I've checked also with two other versions (firefox 3.0.4 and 3.6.19) where same tooltip fonts resist customization but your code have same effect as I have described. And yes I have come along many times to those 2 http pages you mentioned, though there are too many things I don't understand in there, and tried those related codes in http://www.mozilla.org/unix/customizing.html but no success yet. This could be a minor thing to others but I don't like to give up on this...or at least, not yet.

The code works for me on Linux for the toolbar buttons and for long lines on chrome pages like about:config
If it isn't working for you on the toolbars then your Linux distribution may be disabling it somehow.

It seems you're right. I was finally able to customize it (the fonts inside the yellow hoverbox when you hover the pointer above such buttons as "go forward", "go back", "Reload", and others along the navigation tool bar of firefox) by going to these directories : .kde share config ; then editing gtkrc-2.0 by adding the following:

                      style "user-font" {
                      font_name = "Verdana 9"
                      }
                      widget_class "*" style "user-font"
                      gtk-font-name="Verdana 9"

So its not in the userchrome.css file but in another config file in my distro. Again, thanks for your suggestion.
