Firefox 3.5 claims to be 2 times faster than it's 3.x version which is a great news as now every browser is in the race to get fastest Javascript execution engine in it's core.
So I got my Firefox 3.x alert claiming that newer and better version 3.5 is available and it's a recommended upgrade. Just now before couple of hours I have updated to Firefox 3.5 using it's auto-updater feature and when it restored previously open tabs and I noticed first change in this blogs title fonts.
Here, in below image you can see blog post title which has taken "Lucida Grande" as Font to render and it was same for rest of the browsers as well. Because Internet Explorer, Safari and Chrome all display it in the same manner.

Another bug which I have just found during my first day experience with Firefox 3.5 is that it does not show up “title” tag descriptions properly. Instead of showing up light yellow colored tooltip with description it just creates/draws a small rectangle box of around 3×3 pixels without any information.
This has to be fixed during Beta or RC releases, as it is very annoying.
I am not sure if I am doing anything wrong or not sure if it is the side-effect of some other add-ons installed.
