The thing that has really been driving me nust lately is the font-sizes in Firefox on a Linux system. More specificly when I am running Knoppix or Kanotix I find that most apps look good when using KDE except for Firefox. The two problems are the font-size of the Firefox UI are too small and secondly the fonts of certian web sites like google.com were way to small.

But after doing some googling and hacking I have found a reason, a fix and a hack.

The reason the Web Page fonts (google.com) were so small was that I did not have the correct video drivers loaded on my laptop. After getting my head out of my .... I read the Knoppix Cheat codes and found that I needed to use the

boot option.
I applied this boot parameter and web pages in FireFox started rendering in a readable size font.

The other reason some apps do not render well are due to GNOME and KDE incomapabilities. For instance I have the same UI issues in the Bluefish HTML Editor when using it under KDE but Bluefish UI looks fine under GNOME. I have no fix for this.

Anyway after adding the boot parameter most web pages rendered ok but with some the font was too small. That's when I stumbled upon the Minimum Font Size Preference Item. Goto Edit-> Prefferences-> Content-> Then under Fonts & Colors click Advanced and the you'll see a SelectBox for a minum font-size. Change it to 16, OK out of the Preferences UI and then go check out some pages that were rendering poorly.

If these to fixes don't fix it for you I don't what will.

Moving on to the FireFox UI:
To Fix the FireFox UI I did some more googling and found a hack. This hack says to create a userChrome.css in the user home directory with some css that will aid in rendering the FireFox UI.

So the first thing to do is create a css style sheet here:

and then add this css:

Once you've done this restart FireFox and see how things look. If you don't like what you see then continue tewaking and restarting FireFox until your happy with the UI.
