After installing Mozilla with the xft patch as mentioned before this is what it looks like. I had to install the latest Galeon too, but I wanted to do that anyway.
Originally the default font Galeon used was “serif” but the serif fonts didn’t look very good, they’re a bit “busy” or “smudged”. The sans serif fonts though look better IMO. This is the font other apps on the RedHat 8.0 desktop use too. I’ll probably comment later after I’ve used the browser for a few hours, so look out for that!
