I strongly wanted to substitute Mozilla's default search engine with Altavista's. You can't do that with Mozilla alone, so I searched and found a site that allowed you to have additional search engines put into your browser. I kept searching for some, perhaps addicting, Mozilla extension and came to this site, which listed several such extensions, like a Statusbar Clock and the option to work with Amazon.com a little easier if you browse the site a lot. Then near the bottom of that site was a link to this one with extensions like another toolbar with the ability to fake what browser you're using (similarly done through the Debug menu in Safari, except with a Combo Box here), an option to auto-show/hide the sidebar, and a spell-checking and BBCode extension. I recommend installing everything in your user profile, so that if you upgrade Mozilla, you want have to reinstall all the extensions. To use BBCode, install it, highlight a bunch of text in a post/reply, and control-click, and there's this menu item for bbcode, which will put code tags of your pref. around the highlighted text. Boom, your highlighted text is coded automatically. Same goes for the spell-checker, control-click. Oh, and, "one more thing..." Adblock - basically the equivalent of PithHelmet for Safari, which blocks ads, except that AdBlock is free and can block flash ads that Mozilla's default banner ads blocker can't. So nevermind this thread.
