I've downloaded some great themes for Firefox. Unfortunately not all of them works the way they should. The most common problem is disappearing menu text when mouse pointer hover above it.
You see not themes are made for specific edition and version of Firefox. Not all Firefox created equally I suppose. So here's 3 (for now) Firefox themes that I love to use (tested on Linux Firefox 3.0.6)

I love Firefox. Addons (extensions and themes) are the icing on the foxy cake. However, installation always requires a restart. Firefox needs to take a leaf out of Opera's book and install and run without a restart.

However, weep no more with envy at Opera. You can now add and run themes dynamically in Firefox with the Persona extensions. Once installed you can change themes on the fly. These themes are accessed online from Mozilla Labs. Easy and lots of fun. Follow the link above and try them out

Most of us already have Firefox 3 downloaded and installed. If you don’t, head over to Mozilla.com and download a copy. So here it is, a quick list of the top downloaded themes for Firefox 3.

This article explains how to move a full profile (addons, themes, cookies, browsing history, passwords and so on) from Firefox 3.0.x to Firefox 3.1.x beta or any other version, but it also works for synchronizing Firefox on 2 different computers or backing up a full profile of Firefox.

We are now in the process of landing a few refreshed icons for the Firefox 3.5 themes. Across all 4 platforms roughly 25 of the icons are either being tweaked or are entirely new (there were some last minute feature additions, like geolocation). Here are a few highlights.

My top 5 Firefox 3 themes:

1. Past Modern - my favourite.

When I first began using Linux back in 2001, the themes I saw were beautiful but they don't compare to some of the themes I'm seeing lately. I'd like to show you some themes which will, in my opinion, spark more interest in GNOME themes.

If you are reading this post odds are you are one of the 1.2 million people currently enjoying a beta or nightly build of Firefox 3. However are you a big enough Firefox fan that you like to run it simultaneously on 4 different platforms?
