If you want to get out close to the cutting edge in Mozilla browsing the run-up to the v1.2 release means that daily builds are being done on a branch that is very stable. Try out a build from here.

If you have ever wanted to put a different skin or appearance on a browser you might want to try the theme that I've just installed on the latest Mozilla nightly build: Orbit 3+1 1.2.0.0.6.5-dev. You can find it here. I used the second choice that is compatible with Mozilla v1.2 and v1.3 and also with Phoenix 0.3/0.4.

You can find more themes on Mozdev and on Deskmod.

Update: If you want the icons to be really small and to make as much room as possible for the viewed page then try the Little Phoenix theme. I have it installed right now on the Phoenix v0.4 and while the text on the menu bar and pop-down lists is small its readable. The Wood theme also makes the browser's menu bar text and tab text smaller. I think its grainy word background makes the text a bit harder to read though.

I like the way the MozDev site organizes themes. If you want to see all the themes that are compatible with a particular browser then note the little set of icons right above the Themes text in the right hand column. You can click to see only themes that are compatible with your particular Mozilla family browser. For instance, click here for the Phoenix browser themes.
