I wanted to briefly mention a couple of nice features Seamonkey provides but doesn't advertise that much. It's not a secret that if you want to configure the heck out of your seamonkey, clicking through menues is just not enough. I personally use the Edit->Preferences menu as a start, configuring basics. All the real configuration starts in about:config. All the configuration is stored in $HOME/.mozilla/<profile_name>/<some_random_string>.slt/prefs.js. When new profile is created that file is empty. Anything you tweak in Seamonkey gets stored there in the form of:
user_pref("<some_varible>", "<value>");
The first thing I do is disable all the unneded buttons and menus. Out of the box Seamonkey is wasting a lot of useful screen space with garbage like "Personal Toolbar", big image+text navigations buttons, a totally unneeded "Search" button and print button. All this can and should be disabled to get the maximum space dedicated for the content browsing. So I start with disabling "Personal Toolbar", "Component Bar" in View->Show/Hide. Next thing to do is remove the navigation buttons. In Edit->Preferences->Navigator I uncheck all available buttons. What really sucks is that I only can remove Go, Search and Print via the menu. I'm still stuck with unneded "Back", "Forward", "Reload" and "Stop". There is a way to disable all 4 of them. Unfortunately even about:config is useless here. So what I do is edit prefs.js manually. To do that you need to close the browser, because it might overwrite your settings when it's closed.
To remove all this garbage I add the following lines to prefs.js:
user_pref("browser.toolbars.showbutton.back", false);
user_pref("browser.toolbars.showbutton.bookmarks", false);
user_pref("browser.toolbars.showbutton.forward", false);
user_pref("browser.toolbars.showbutton.home", false);
user_pref("browser.toolbars.showbutton.print", false);
user_pref("browser.toolbars.showbutton.reload", false);
user_pref("browser.toolbars.showbutton.search", false);
user_pref("browser.toolbars.showbutton.stop", false);
Next time I start my browser - it looks much cleaner. Next annoying thing to disable is the startup homepage. I always set it to be the blank page. IMO, having a site where you go right after you start your browser is just lame. Wastes traffic and time you wait untill this site opens up. That can be done via Edit->Preferences or by setting "browser.startup.page" to 0 in about:config.
Just by doing these simple steps I now have a nice looking browser, with a lot of useful space in the address bar, status bar and the content area itself.
