Google made their toolbar for the majority of the Internet-users and they, if you like it or not, use Internet Explorer. But the Googlebar-project was started to create this ideal bar for Mozilla:
Googlebar-project
I you like other search-engines, you should also have a look at the
MyCroft-project. It creates Sherlock-plugins for use in Mozilla's sidebar. So you can search your favorite site from the sidebar.
About the icons: there are nice new :
icon-sets
Hey, I see that Deskmod also lists
Mozilla-splashscreens They even have quite unique ones. I know some more, but have not seen these ones yet.
About Mozilla 1.1 alpha: I currently use it because I am translating Mozilla to the Dutch language. But it has an ugly bug when one changes the language of the browser. So I suggest everyone waits for Mozilla 1.1 beta (which is close according to Mozillazine.org).
What is in Mozilla 1.1 alpha ? The things that did not make Mozilla 1.0 (mostly because of instability or because it was not completely ready). So with Mozilla 1.1 one can block images from certain servers (for example: the advertising-networks and such). There also is a download-manager included. And there are some more of these nice additional functions.
Greetings,
