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

In like a lion, out like a Snow Leopard? Apple changed its spots on Sun's ZFS fairly quickly. This week the company shutterd the ZFS Project on Mac OS Forge, and there's no hide or hair of ZFS to be found in Snow Leopard. But as with all things open source, there's a light at the end of the tunnel.

Among Firefox 3 pending improvements it a cool tab preview feature that shows actual thumbnails of the currently opened tabs. The feature is currently available as an experimental extension developed by Dão Gottwald, but could make its way to Firefox 3 final code.

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.

Konqueror as a web browser still unfortunately lags quite a way behind Firefox in terms of compatibility. For that reason, many KDE users stick with Firefox, despite the poorer integration between the desktop environment and the browser. I have just come across a theme for Firefox 3.0 designed to make Firefox fit in better on a KDE 4.0 desktop

Brand new Firefox 4.0 is on its final descent. Be it the introduction of awesome TabCandy feature or the new super fast "JaegerMonkey" JavaScript engine, Firefox 4.0 is all over the news for all the right reasons. I think this is the best time to introduce some cool Firefox commercials/videos. Take a look.

From its humble beginning a decade ago, Mozilla Firefox is now a force to reckon with. Firefox 3.5 is now the most popular web browser in the world. Check out this nice collection of 15 awesome Firefox wallpapers.
