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.

Blog Title in FireFox-3.x with Font-Family: "Union","Lucida Grande","Lucida Sans Unicode",Arial,Helvetica

Well now let’s see what Firefox 3.5 has to offer with similar Font-Family attribute?

See, above image shows the way presentation of fonts will be changed. So in short from the first and immediate observation it looks like “Union” fonts do have their existence and Firefox 3.5 has proved it. So people like me using such fonts on WordPress themes or similar CMS or publishing applications may need to change their stylesheets or at least confirm once by checking their website with Firefox 3.5 for consistence user experience. As of now I am not sure that whether it’s CSS3 impact or what? as FF3.5 has CSS3 support too. But whatever it is we need to be ready for the change..!

If you had any recent experience after upgrading to Firefox 3.5 please share on this post by replying as comments.
