I just installed Firefox 18 and I was horrified to see Gmail's font rendering (the problem occurs also in Iceweasel 18 from Debian). The problem does not occur in Chromium.
Now, I tried a couple of things:
- I removed Arial from my computer.
- I followed a hint in the SUSE forums (the last one customising the Chrome CSS files).
I still don't get it to work. Does someone know how to change it? What if I don't want to use Arial at all in Gmail? Can I do something about it?
Why does Firefox misbehave?
I found the solution to problem how to change the font in GMail, a Greasemonkey script for GMAIL. Unfortunatly, the font are still blury. It seems like a bug in FF for Linux.
