Yes that works.
I used the sample file in:
defaults/profile/chrome/userChrome-example.css
(subdir under mozilla install dir)
which I copied to the subdir of my home dir:
.mozilla/default/e5egmpss.slt/chrome/userChrome.css
I put in the following code:
* {
font-family: sans-serif !important
}
* {
font-size: 10pt !important
}
Now I have the exact fonts in Mozilla V1.4 (for everything) as what I had with v1.2 which is what came with the Redhat V9 distribution. Thanks for the help.
